EXECUTIVE SUMMARY
1. PREAMBLE
Minerals are the chief source of present phase of industrialization, and play an
important role in the present phase of the national economy and overall
development of the nation.
India is endowed with significant mineral resources. India produces 89 minerals
out of which 4 are fuel minerals, 11 metallic, 52 non-metallic and 22 minor
minerals.
State is enriched with good deposit of manganese ore mainly spread over in the
Balaghat, Chhindwara and Jhabua districts. The total reserves of 23.64 million
tonnes of manganese ore are available in the State constituting 14.09% of total
national reserve. The "Bharveli manganese mine" in Balaghat district is largest
underground mine operating in Asian sub-continent. The manganese ore deposits
of the State are being exploited mainly by the Manganese Ore India Limited.
During the year 2001-02, manganese ore has contributed Rs. 1.51 crores as
royalty to the State Exchequer.
43.086ha Manganese ore Mining project is located at village – Ramrama, Tahsil
Waraseoni; Balaghat District (MP). Land use of the area is Govt. land and Own land.
43.086 Ha mining lease area is being operated by the lessee firm M/s A. P. Trivedi

4. REASON FOR ENVIRONMENTAL IMPACT ASSESSMENT (EIA)
The impact of mine on the environment depends to a large extent on its location
with respect to Human settlements, meteorological conditions, ambient air quality,
water bodies, agricultural and forest land etc.
Most of the adverse impacts of mines are amenable to technological control by
providing necessary preventive and control measures and finally through effective
environmental management of the operating mines. Keeping in view the likely
impacts of mines on environment, this Rapid environment impact assessment
report has been prepared for submission to State Pollution Control Board and
Ministry for Environment and Forests (MoEF) for clearance of the proposed mining
area.

Mining Method
(a) Present & proposed mining method:
Existing mining is being carried out by open cast manual method of mining using
hand tools such as spades, chisel, hammer etc. Lumps of Manganese Ore are being
transported from pit bottom to surface manually on head load using tasla where
ever required sorting of Manganese Ore is being done and the waste in the form of
country rock mica schist. Manganese Ore is being transported by truck/dumper to
user industries. Loading of mineral in to truck dumper is being done manually. The
underground development work is in progress. Earlier one vertical shaft has been
sunk up to 54m depth i.e. 280Mrl and from this place drives and cross cuts are have
been developed for another 50m lateral length. From quarry III one inclined is in
progress for 8-10m depth.
Reasons for choosing the work site are:
As the development already started with respect to manganese ore mineralization
trend and in ensuing years with proper bench development from east to west
within quarry
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 5 M/s Creative Enviro Services, Bhopal
Lay out of haulage road: Present haulage roads 2-3m wide will be maintained and at
required places it will be laid at maximum 1: 16 gradient from surface stack yard to
pit bottom at 308mrl with in bye roads to faces of individual benches.
Development cum production bench: Uniform eight benches of 3-5m height with
6m advance of each bench in semi mechanized mining will be developed (however
sub benching will be done to facilitate jackhammer drilling & blasting in while doing
the manual mining otherwise wagon drill will do hole at one stroke.). Width of
benches will be as per DGMS requirements and under OTFM –A category i.e.
minimum 6m will be maintained at every bench.
Adequate steps shall be taken to ensure that the benches are kept dressed at tall
times. Special care shall be taken when any slip or other planes of weakness or
other geological disturbances exist, so as to prevent danger to the work person. No
person shall be engaged on work or allowed to travel close to high sides/benches
from which he is likely to fall more than 1m vertically down, unless he is provided
with and use of safety belt or rope.

Remarks: In all quarries the manganese ore band of 5-6m thick is running NWW-
SEE direction with two dipping direction (dip is 520 one is towards the north
(quarry no. III-II) and another one is in south direction in quarry no. I, this may be
due to folding and tectonic disturbance.
(b) Proposed Method:
Opencast & Underground method of mining will be done. All operations of mining
will be done by deployment of heavy earth moving machineries for excavation,
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 6 M/s Creative Enviro Services, Bhopal
loading & transport. Deep hole drilling will be done for blasting purpose. Blasting
will be on regular basis. Random holes of 2.8m depth/deep hole drilling will be
done. Various mining activities such as drilling, blasting, loading and transportation
will be so conducted as to ensure maximum mineral conservation and minimum
environmental degradation. While planning, quality parameter of the deposit has
been taken care of so as to have maximum blending ratio. As in the lease area the
mineralization has the waste in the form micaceous schist therefore the proposal of
excavation is given in cubic meter. Excavation of manganese ore and waste will be
done by loader –cum- excavator. Drilling in hard strata will be done by Jackhammer
of hole dia. 32mm. or deep bore hole 85mm dia will be by wagon drill. Blasting will
be carried out for heaving effect and fragmentation to the deposit. Blasted Ore will
be loaded in to the dumpers by loaders and will be transported to the stacking yard
then after getting the sorting of manganese ore of different grade will be dispatched
to prior destination like – Ferroalloy plants. Secondary blasting will not be required.
The waste will be in the form of country rock which will be handled by machines
and loaded to dumpers and unloaded to proposed backfilling/ dumping yard. The
underground development work is in proposed. Earlier one vertical shaft has been
sunk up to 54m depth i.e. 280Mrl and from this place drives and cross cuts are have
been developed for another 50-60m length. During the period one auxiliary ore
body has been encountered are 282-280mrl. From quarry III one inclined is in
progress for 8-10m depth.
Year wise Development/production plan: -
For opencast mining method
Opencast method of mining (A category other than fully mechanized mines) has
been proposed. All operations of mining will be been done by deployment of heavy
earth moving machineries for excavation, loading & transport. Regular drilling will
be done for heaving purpose in the lease area. Blasting will be done on regular
basis. Random holes of 2.8m depth/deep hole drilling will be done. Haul road has
been extended to every working bench and to the floor of the quarry. As per earlier
approved SOM first five year of SOM period has already been ended by 31-3-2010
the proposal of the present SOM is given for its period i.e. 2010-11 to 2014-15 with
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 7 M/s Creative Enviro Services, Bhopal
average production average 14272 tonnes from open cast mining and rest average
4500t will be from underground mining development proposal thus in a year total
average production will be about 18000t (average) under the category of mining
activity A category (OTFM). The mining operations are proposed within the quarry-
I which will be developed with eight development cum production benches of 3-
5m in country rock with 6m bench width thus during the year the RL will reach
from 324 m to 297m. The recovery of manganese ore will be 100% by volume and
finally the production will be loaded to the trucks and dumpers mechanically and
manually. Proposed mining is suggested lateral and depth wise, in keeping view of
systematic development of benches and providing the proper shape.
For underground mining work
i) Mode of entry
One vertical shaft sunk up to 54m in depth. The shaft top RL is 334m and shaft
bottom RL is 280m. At 280 RL lessee has developed drives, cross cuts and a
raise to locate the ore body. During raising, located at distance of 34Mtrs
(lateral) from shaft bottom one auxiliary ore body has been encountered (280m
to 282m in the eastern direction).
As proposed A Main Incline Shaft is being developed at the pit bottom of Quarry
No– III along the footwall of the main body. The Main Incline Shaft’s current
length as on 20-6-2010 is 9 Mtr. The approx inclination is 300-350degrees. The
Main Incline Shaft Bottom RL 311m.

and ATP-2 and duct pipe in the main vertical shaft) as shown in the five year
plan. The proposed development in ensuing two/three years to connect the
main inclined opening to the veridical shaft opening thus cross ventilation will
be available with this proposal.
iii) Underground layout
The present exploratory bore holes towards the quarry III proved quarry –III
manganese ore body depth wise extension up to 240mrl, presently vertical shaft
has already been sunk upto a depth of about 54m i.e. RL of 280m and cross cuts
have driven to locate the ore body.
Further one incline shaft is in progress at the bottom of quarry III and present
size of incline is 3x2M and the RL has been reached to 317M along the footwall
of main ore body.
The proposed under working as under:
1. Further sinking of vertical shaft
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 10 M/s Creative Enviro Services, Bhopal
• The present position of sunken vertical shaft is not meeting to the gradient
from bottom RL to inclined RL i.e. quarry IIII MRL is of 320m and vertical
shaft MRL is 280m keeping proved geological reserves status depth wise and
proposed layout from 240mRL to 340mRL hence it has been advised to sunk
the vertical shaft for another 40m to meet the proper gradient at 25m
interval.
• The main inclined G1 will be further developed with winzes and during two
years inclined out let will be connecting to vertical shaft level thus two outlet
to the working established. The proposed underground development will be
completed in following way
• By the end of 2012-13/2013-14, there is a proposal of additional one G2
incline to developed at the east of main incline G1 and the level of this G2
incline will 320M and this incline will further develop with drives, winzes
and so on
a) Further deepening of vertical shaft for another 40m i.e. 280 mRL will go
down to 240mRL
Proposal period: 2010-2011
Standard time required for sinking of vertical shaft
Dia of shaft is 4.6m and radius will be 2.3m
Proposed sinking is 40m
Volume=
3.14X2.3X2.3X40=664M3
Total working days 250 days
Total no. of labor =10
Per day per labor out =664/250x10=0.265m3
Thus 40m shaft sinking will be done in 250days or one year
b) Subsequent development of drives, winzes and raises
The underground working layout has been proposed in the form drives,
crosscuts winzes from inclined and raises from the vertical shaft drive.
The standard calculation
Face: 2.4x2.1m
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 11 M/s Creative Enviro Services, Bhopal
Length=25m
Average volume=25X2.4X2.1=126M3
In general 6 people can progress 10m lateral progress in a month i.e.
25days
Proposed shift: 2
Hence the labor =6x2=12
One drive/winze/raise =25m
Hence the total volume will be =126m3 in a 2.5months or in a
monthe126/2.5=50.4m3
Thus with 6labour in two shift will be 12
Per day excavation: 50.4m3/no. of labor x working days
=50.4/12x250=0.168m3
Per year average development through drives/winze/cross-cuts/raise
will be average 238m
Hence the total quantum of will be =238mx2.4mx2.1m=1200m3
Per day quantum=1200m3/250=4.8m3
Per man out put =0.168m3
Hence required labor =4.8/0.168=29
During the ensuing the five year period working following development will also be
perform simultaneously which are as follows:
i) Development of road: During the ensuing the five year about 500m (length) and
1-4m (width) road will be developed at a gradient of 1:16 out which 250-300m will
be in the working pit and rest road will be developed to connect the main kuchha
road.
ii) Retaining Wall: During the ensuing five year working waste will be keep in the
western barrier zone and its stability will maintain by constructing the retaining
wall as per the configuration made in the waste management.
iii) Garland: As the five year proposal are given at gentle slope, in the rainy season,
water will accumulate in the working pit hence therefore proposal of about 300m
garland around the working pit or according to their gradient which will protect the
pit and the garland drain will be drained according to the respective gradient

complete development of the Mining.
Haulage drives
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 13 M/s Creative Enviro Services, Bhopal
Shaft, ’X’ cuts from shaft, corresponding ore drives shall be used as haulage dries for
transport of ore, other material and services. The size of all above drives shall be
2.4m (W) X2.1 (HT). Proposed incline shaft and ore drives from main incline used
for haulage of or ore other materials and services. From main incline necessary
protection will be given for inflow of water into the incline by providing 10m or so
high wall or garland to obstruct the inflow of water.
Stopping permission
As per proposed planning from main inclined and vertical shaft the stoppes will be
ready by the end of second or third year and consecutive development it is expected
that one to two stoppes will be ready for further permission every year.
Ventilation
Presently ventilation is providing by the compressed air/exhaust fan operated by
125KVA DG set near the vertical shaft. The compressed air provided by the air
conduits at the APT BH-1, APT BH-2 and duct through the main vertical shaft and its
circulation come through the vertical shaft. Now by the end of the 2011-2012
proposals are given to connect the main inclined to vertical shaft with
drives/winzes/raises and cross ventilation will be established by the end of 2011-
2012. During the exploration development for main incline to vertical shaft
ventilation no. of working faces shall be effected by electrically driven auxiliary
forcing fans.
Transportation of ore and waste:
As the lease area is having the mineralization Ferro alloy grade manganese ore rib
which has the interburden of country rock as waste which re-handling will be
required, the different grade of manganese ore will be sorted will be kept near the
stacking yard while the waste will be used for backfilling the excavation made in the
northeast part of the lease area zone.
Mine Drainage
Maximum water flow in the open pits shall be during the monsoon season .To
reduce the inflow of rain water in the existing pits it is proposed to have garland
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 14 M/s Creative Enviro Services, Bhopal
drain taking the rainwater out of the lease area. To protect the main inclined from
quarry -III water, one 10m or so height RCC wall is proposed around the main
inclined. Pumps of adequate capacity shall be in installed in pit no. I & III and
necessary efforts will be done to keep the water level one meter below the entry of
G incline to prevent flooding of workings of main incline. However there would still
be ground water seepage in the underground working and same shall be dealt with
combination of pneumatic and electric pump at faces and underground pump
stations. The present intake and out take of water from main vertical shaft is about
15lps and the lessee has the capacity of pumps up to 25lps. This would enable to
keep the working area dry and to execute uninterrupted development work. It has
been discharged with suitable capacities of electric pumps are installed at main
sump at the bottom of each main incline. Suitable capacities of sump, suitable size of
de-watering pipes are laid for de-watering to surface. The pumped out water will be
used for agricultural purpose for the surrounding agricultural land. The discharge
water will first pass through the settling tanks where suspended particles will
settled before its discharge for agricultural use, as surrounding area is agricultural
land.
Solid Waste Management
In proposed underground mining operations, the mine waste consists of pegmatite
veins in ore body, clay pockets and silicious Manganese ore and Gondite and
mineralized rejects, fines etc. The lessee has decided to develop the opencast &
underground opening in the ore body itself following the ore body in dip and strike
direction. As such no waste is expected to be generated. In general existing present
quality of OB is in form of weathered siliceous lateritic loamy soil mixed with
intercalated waste as mica schist. The waste will be generated from development
benches as of mica schist along interstitial quartzite. No top soil will be generated
during the proposal period. During the first five year 78638M3 wastes will be as of
mica schist along interstitial quartzite and this waste will be utilized for the
backfilling the excavation made in the NE part of the area and rest will be dumped
in SW part of the lease area. During the 6th to lease period about 750000m3 wastes
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine
Ex. Summary 15 M/s Creative Enviro Services, Bhopal
will be generated which will be dumped by making of dump of 300x16xx16-17m in
the southeast part of the lease area.
Resource Requirement
The present proposal is of ongoing mining activity at mining lease area of 43.086ha
at village Ramrama tehsil- Waraseoni & Dist. Balaghat, MP. For efficient operation of
the Mines all necessary utilities will be made available, a brief description of the
same is given below.
a) Storage facility

The Surface water bodies in the study area mainly Katngajhari Canal-2.5km-SE,
Chapa Tank-0.75-SW, Katangjhari Tank-1.25km-ESE, Kas Nalla- 1.5km-W, Dhokriya
Nalla- 3.0km-SW, Tondiya Nalla-7.25km-ESE, Sarathi Nadi-N-8.5km, Sarathi Tank-
NE-8.5km respectably from mine. The water from Katangjhari tank, chapa tank and
sarathi tank is used for irrigation purpose. In addition, most of the water bodies are
dry during the summer months excluding those water bodies (worked out
quarries), which are situated in the study area. These water bodies are filled with
rainwater and seepage/discharge water from abandoned mine works.
The data conform to the water quality standards for most of the parameters. The
dissolved oxygen levels range between 5.4 to 5.8mg/l, Total Hardness ranges from
186 to 226 mg/l. The heavy metal content has been observed within the limit. The
physico-chemical and biological analysis revealed that all the parameters are well
within the prescribed limits of IS: 2296.
Ground Water
The study region receives about 1600 mm of rainfall and which plays an important
role in recharging of ground water. High lands ensure quick surface runoff and the
precipitation received in low–lying area contribute to a great extent in building of
ground water reserve of the area.
Water supply in the most of the villages depends on ground water resources. Well
water is used for domestic as well as irrigation purposes. Ground Water quality
analysis was carried out at 4 locations and the frequency of sampling was once
/month/station. Ground water samples were examined for physico-chemical,
heavy metals and bacteriological parameters in order to assess the effect of
industrial and other activities on ground water. The samples were collected and
analysed as per the procedures specified in “standard Methods for the examination
of water & Wastewater” published by American Public Health association (APHA).
pH in ground water sample was observed to be in the range 7.3 to 7.41. The value of Iron
and hardness were observed in the range of 0.03 to 0.06mg/l and 124 to 168 mg/l
respectively. Whereas heavy metal was found to be within the limit.

7. IMPACT ASSESSMENT
Mining activities is bound to have an adverse impact on existent environment. An
understanding of the nature and extent of various impacts is essential in devising
the methods and advance planning to mitigate the impacts and ultimately restore
the land to useful conditions.
8. IMPACT EVALUATION
An attempt has been made to evaluate the impact of project in terms of both quality
and quantity by using modified matrix method for crucial environmental
parameters. The environmental impact evaluation of possible effects as a result of
proposed mining area is primarily based on study of objectives, process,
surrounding environment etc. The aspects such as water, air, land and related
issues have been assessed on the basis of mining operations for similar activity. The
environmental impacts identify the possible relationship of proposed mining
operations with respect to environmental parameters. Their relationship can be
beneficial or adverse and can be further classified as short term, long term,
reversible, irreversible, local or regional.
9. ENVIRONMENT MANAGEMENT PLAN
9.1 Reclamation of Land
Reclamation and rehabilitation is will be proposed during proposed five year
working, entire mine waste will be used for backfilling purposed. Waste generated
during the proposal period will be partly used for the backfilling. Systematic
reclamation and afforestation of mined out areas will be carried out in lease area so
as to cover the entire worked out area before expiry of mining lease. Since further
exploration is proposed to completely delineate ore bearing areas within the
leasehold, complete reclamation programme cannot be given at this juncture but
waste will be spread in worked out areas to the maximum extent possible.
9.2 Green Belt Development
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine

9.3 Measures to Improve Socio-Economic Conditions
The impacts of the project would be felt in an integrated manner on the socio-
economic environment in the study area. There is no village in core zone and
further no displacement is required for the proposed project and therefore impact
will be positive side rather negative. The impacts on the different components viz
employment, housing, educational, and medical and transport facilities, fuel
availability, economics, status, health agriculture is not significant because size of
project is very small. However, it would definitely increase the employment
M/s A. P. Trivedi Sons, Balaghat Executive Summary
REIA for 43.086ha Ramrama Manganese ore Mine

opportunity (primary as well as secondary) in the project area. Some of these
impacts would be beneficial.
• The project will have a strong positive employment and income effect, both
direct as well as indirect.
• Migrant-Non migrant ratio shall shift towards migrant side. This will happen
because of (i) better employment opportunities due to this project and (ii)
relatively low agricultural yield through traditional agricultural practice
with monocrops.
• The project shall speed up the growing view on importance of education
among people in study area.
• The project is going to bring about changes in the pattern of demand from
food to non-food items if sufficient income is generated.
• The project is not going to influence the existing traditional agricultural
situation significantly. It may help to improve agricultural production by way
of providing additional income to the farms from supplementary sources.
• People perceive that the project will bring handful gains by way of creating
significant job opportunities along with development of social infrastructure.
9.4 Air Pollution Control Measures
Following measures shall be taken to mitigate the effect of mining operation over
ambient air environment:
1. Regular spraying of water by water sprinkling system over haulage roads.
2. To reduce dust generation during loading operation water shall be sprayed
over the muck pile to the loaded;
3. To reduce dust generation during plying of dumpers on the haul road. Water
sprinkling is done at frequent intervals. Water sprinklers shall be installed
at the mine haulage road;
4. To reduce spread of dust, plantation along the mining lease boundary and
plantation shall be also done along haul roads.
5. Periodic maintenance of haulage roads.
