Hard Rock Underground Mining

Hard Rock Underground Mining

Hard Rock at a Glance

• Focused on the extraction

of hard rock minerals such

as Gold, Nickel, Copper, Tin,

etc.

• Typically very hot due to

geothermal heat in addition

to heat generated by

vehicles

• Operating costs can be very

high, so productivity is key,

especially $/ton

• Ventilation is a key enabler

by dissipating heat &

gasses allows people to

work in the mine.

Extraction

Typically

Supported by

3 pieces of

production

equipment

Drilling Jumbo’s – Drill

into Ore for body for

explosive placement

Load Haul Dump (LHD)

– Load and Haul the

fragmented ore to a

haul truck or ore pass

Haul Truck– Transports

Ore out of the mine or to a

hoist/ore pass system

Block Caving: A Key UG HR Mining Method

http://www.aulados.net/Geologia_yacimientos/Geologia_Minas/Block_caving_1.jpg

• Series of undercut tunnels developed below column of ore

• Sequence of drilling/blasting occurs to fracture ore and channel into drawbells of ore

• Ore is extracted at bottom of drawbell(called drawpoints)

• Ore is typically deposited at orepasses(usually located at end of drift) sized/crushed and transported to surface (via trucks/belts)

Problem Statement

16

Location: Pocono’s,Pennsylvania:• A major Rare Earth Element (REE) ore

deposit was discovered deep within the Pocono Mount Region of Pennsylvania.

• Mine development infrastructure has been installed over the last 5 years to permit ore extraction and the mine operator wants to start making money. The ore body lies approximately 3000 m below the earth’s surface.

• Due to the mine depth, traditional diesel equipment will be difficult to utilize as higher temperatures, humidity, and gas emissions will be encountered requiring significant ventilation & cooling infrastructure. This will result in high operating costs and make it prohibitive to start mine production.

• Additionally the environmental conditions for the mine workers needs to be a top priority.

17

Problem Statement:• The mine owner is soliciting an

engineering design team to develop a strategy to extract the ore in a cost efficient & environmentally friendly manner.

• The strategy should include but not be limited to alternative types of mobile equipment for production, alternative energy sources for mobile equipment or other methods that could exploit the current mine setup.

• Strategy Considerations:i. Mitigation of Airborne Contamination

ii. Lifecycle Management of the Ore

iii. Environmental Management

iv. Worker Occupational Health & Safety

v. Operating Costs & Productivity

vi. Local Community Engagement

vii. Waste Management/Disposal

viii. Mine Closure/Rehab Plan

18

Deliverables:• Each team should research, develop, and

submit an extraction strategy in line with the mine owners expectations.

• Your submission should include:i. Rationale for the recommendationsii. Description of alternative concepts

and their evaluationiii. Systems diagram(s)iv. Concept of Operationsv. Environmental analysisvi. Assessment of important aspects of

your system for feasibility and adoption, including public opinion

vii. Economic viability of the systemviii. CAD drawingsix. A Model or prototype of a

component of the overall system

Pocono Mountain REE Mine

21

a. The mine has been setup as a Block Cave operation with a ramp from the surface to the

production level. This ramp was intended to be the main transport for ore to exit the mine

(Note: there is no hoist system that you might see in your research of block cave mines)

b. The Rare-Earth Element Concentration is uniform throughout the ore deposit

c. The Rare-Earth Ore is worth $10,000 per ton extracted

d. The Haul Truck Ramp from the extraction level to the surface processing plant is 15.3 km

long at a constant 20% Grade

e. Assume that each draw point provides a continuous flow of ore and that there are no

hang-ups, downtime, or large boulders to break up during the extraction process.

f. There are 100 Draw Points in the Mine

g. The Average Distance between a Draw Point and Haul Truck pickup locations is 300 meters

h. The REE ore deposit host rock is fine to medium grained sandstone, siltstone and

conglomerate and is considered reasonably stable and self-supporting over approximately

90% on the mine, structural roof/rock support systems will be needed in the remaining

portion of the mine.

i. Estimated average groundwater inflow (drainage) into the REE mine is 10 gallons per

minute
