2.1 Identification of project and project proponent

Project: Mandakini – B Coal Mining Project (Capacity-20.0 MTPA)

The Mandakini–B coal mining project is located in Talcher Coalfields in Angul district of Odisha state. The block has been allocated to NTPC Ltd., for captive mining for supply of coal to their Telangana Super Thermal Power Stations by Ministry of Coal, Government of India vide F.No.103/33/2015NA dated 8th Aug 2016 for a total area of 20.73 sq. km.

Mining Plan for the block prepared by CMPDIL envisages a production capacity

of 20 MTPA. Project proponent

NTPC Limited (A Govt. of India Enterprise), is the largest power generating company in India. It was set up by Government of India (GoI) in November, 1975 with the objective of planning, promoting and organizing integrated development of thermal power in the country. NTPC was conferred “Maharatna” status by GoI in 2010. NTPC is now emerging as a well-diversified company on its way of becoming an Integrated Power Major, having entered into hydro power, coal mining, power trading, equipment manufacturing, power distribution business and renewable energy generation. Presently, NTPC generates power from Coal, Gas, Hydro and Renewable (i.e. Solar and Wind) projects. With an installed capacity of 52,946 MW (as on December, 2018), NTPC is the largest power generating major in the country. Additional capacity of about 21,000 MW is under construction at various locations in India. NTPC is also allotted 10 coal blocks, out of which 2 are in operation. About 6 MTPA coal is being produced from Pakri barwadih coal mine and about 0.5 MTPA from Dulanga coal mine.

2.2 Need for the project and its importance to the country and or region

Coal is the most important and abundant fossil fuel in India. It accounts for 55% of the country's energy need. The country's industrial heritage was built upon indigenous coal.




Commercial primary energy consumption in India has grown by about 700% in the last four decades. The current per capita commercial primary energy consumption in India is about 350 kg/year which is well below that of developed countries. Driven by the rising population, expanding economy and a quest for improved quality of life, energy usage in India is expected to rise. Considering the limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on hydel project and geo-political perception of nuclear power, coal will continue to occupy centre-stage of India's energy scenario. Indian coal offers a unique eco-friendly fuel source to domestic energy market for the next century and beyond.

Through sustained programme of investment and greater thrust on application of

modern technologies, it has been possible to raise the production of coal from a level of about 70 million tonnes at the time of nationalization of coal mines in early 1970's to 676.48 (Provisional) million tonnes (All India) in 2017-18 (Source: http://coal.nic.in/content/coal-indian-energy-choice assessed on 29.05.2018).

The importance of coal as a fuel for power generation cannot be overestimated.

The economic development of any country largely depends upon its industrial progress and the industrial development of a country largely depends upon its possessing a sufficiently large stock of this most valuable mineral product. Coal is regarded as the backbone of power generation in India. There is huge demand for power in India. Power is essential and most important factor for industrial and business set up. India’s coal position is quite encouraging and it offers good prospects for the development of this industry. During 2011, India was the third largest coal producing country in the world. Hence, coal is an important constituent of the present Indian economy. The total reserves of coal in India have been over 290 billion metric tons. The coalfields in India are located mostly in Odisha, Madhya Pradesh, Chhattisgarh, Uttar Pradesh, Meghalaya, Telangana, West Bengal, Sikkim, Arunachal Pradesh and Bihar. The power sector is the largest consumer of coal followed by the iron & steel and cement segments. India is the world’s fifth largest energy consumer, accounting for 4.1% of the global energy consumption. Of the total electricity consumed in the country, approximately 80% is produced from coal (Source: https://www.importantindia.com/21958/importance-of-coal-in-indian-economy assessed on 29.05.2018).

2.3 Demand-supply gap

The overall long-term demand of coal is closely linked to the performance of the end-use sectors. In India, the end-use sectors of coal mainly include electricity, iron and steel and cement. Demand from the unorganized small scale sector comprising primarily of the brick and ceramic industry is relatively large though infirm as users switch between coal, firewood and biomass depending on their relative prices. Other industries using coal have only a marginal impact on the long-term demand for coal.

As per the Report of the Working Group for coal & lignite in the terminal year of

XII Plan (2016-17), the total demand of coal in different projections was at 980.50




million tonnes. Of these, the demand for non-coking is assessed at 913.30 million tonnes and coking coal at 67.20 million tonnes. As against these demands the production of non-coking coal is projected at 683.30 million tonnes and coking coal at 31.70 million tonnes in the terminal year of XIIth Plan. The total supply projection of coal through various sources i.e. CIL in 556.40 million tonnes (coking coal are in 15.74 million tonnes and non-coking in 540.66 million tonnes); SCCL in 57 million tonnes under non-coking coal and others are in 101.60 million tonnes (15.96 million tonnes are in coking coal and 85.64 million tonnes in non-coking coal). This leaves a gap of 265.50 million tonnes between demand and indigenous availability comprising of 35.50 million tonnes of coking coal and 230.00 million tonnes of non-coking coal is to be met through imports. (Source: Indian Minerals Year Book 2017, IBM, March 2018).

Some of this shortfall will be met by supplies from captive coal blocks and rest

through imports. Also, the choice between the supplies from domestic and imported coal is mainly driven by timely availability of coal from domestic sources, quality requirements and the economics of landed cost of coal at the end-use plant. Captive coal mining in India was, gradually, being permitted by amending the Coal Mines Nationalization Act, primarily in iron and steel making, power generation and cement production. Hence, it became important for India to secure coal through imports from international market to meet their significantly rising coal demand. However, import is mainly dependent on availability of coal in global market, increasing competitive scenario and affordability

The Mandakini–B Coal Block has been planned for a targeted capacity of 20 MTPA. The production will be used in Telangana Super Thermal Power Project of NTPC. Beside this, coal, if required will be supplied to other power plants of NTPC as per applicable rules.

2.4 Imports vs. indigenous production

The proposed mine lies within India, hence import not applicable. 2.5 Export possibility

There will not be any export of coal from the coal mine. Coal shall be used in Telangana Super Thermal Power Project of NTPC Ltd. Coal from the block shall be transported to railway siding located beyond the Northern Boundary of the Mine through 60 T dumpers and Conveyor System from the surface of the mine. The coal has to be transported from Mandakini-B to Telengana STPP which is at distance of approximate 950 km.

2.6 Domestic/ export markets

Entire coal produced from the mine shall be used in Telangana Super Thermal Power Project of NTPC Ltd. Beside this, balance coal, if required will be supplied to other power plants of NTPC as per applicable rules.

2.7 Employment generation (direct and indirect)

Total manpower required for the mine will approximately be 1700 persons and the project is likely to generate indirect employment opportunities. The




employment opportunities will include almost all categories, viz. management, supervisory, highly skilled, skilled, semi-skilled, and unskilled workmen etc.

3.0 PROJECT DESCRIPTION

The ML area of Mandakini–B Block is 2078 Ha. The peak rated capacity of mine shall be 20 MTPA.

3.5 Project description with process details

Open-cast mining method is selected in view of workable thickness of coal seams and favourable overburden to coal ratio (2.25 m3/t). Average Seam gradient is from 4-7 degrees. Shovel & Dumper combination and Surface miner is recommended in view of multiple seams and equal nos. of inter burden layers to be tackled, an equipment system which is capable of dealing many layers at a time (flexibility) of operations with the help of smaller units has been recommended as shovel dumper combination. For tackling 20 MTPA and 34 - 50 Mm3 OB from several locations in the mine, comparatively medium and higher size shovels of up to 10 to 12 m3 bucket capacity have been envisaged along with 100 T matching capacity of rear dumpers for OB and 100 – 110 T surface miner along with 5-7 cum Front End Loaders in combination with 60 T Dumpers (Coal Body) for coal have been envisaged. Single pit has been planned for mining. The block has an East-West strike and dipping on the Northern side. It is proposed to open the mine from the Southern side and access the Seam I E which would form the pit floor. The minimum depth of Seam I E is around 90 m. As the working front advances Northwards, upper seams would be encountered. During later years the mine shall be advance towards South in the dip side. Coal production shall start in P–1 i.e., 1st production year (initial 2 years has been considered for construction phase mentioned as C1 and C2). From P – 8 (i.e., 8th production year of mining operations) the mine will achieve the peak rated capacity of 20 MTPA. The mining operations proceed towards North and in-pit dumping of overburden starts P – 6 year. To cater the production of 20 MTPA mine-end conveyor system is proposed. Refer the surface plan, geological plan and geological section is given in Annexure II, Annexure III and Annexure IV respectively The total life of mine is 39 years (2 years of construction + 37 years of production) and given in Table 3.
