Coal Mining Industry
• Main features of U.S. mines
– No or very few non‐production personnel at mine level (e.g., about 300 employees at Cumberland Mine producing 6.5 million tons clean coal/year)
– Mine life varies from several years to 30 years depending on the reserves and market forces
– Mine size varies from several thousand tons to 111 million tpy
– Common design tasks handled at corporate level
– Contractors are heavily used for special or difficult tasks
10National Energy Technology Laboratory
Coal Mining Industry
• Main challenges of the U.S. Coal Industry– Mine Safety is first priority
– Ground control problems
• Roof falls, cutter roof, floor heaving
• Entry stability in deep mines (>500 m)
• Surface subsidence, especially in the east, mid west
• Longwall tail entry support
– Environment limitations
• Air and water pollution
• Permitting issues
• Environment groups
– Depletion of good coal and good geologic conditions
– Competition from gas industry
– Longwall mine production limited by ventilation capability

Underground Coal Mining Methods
• Room and pillar method
– Very flexible, good for mining small and irregular reserves
– Development mining only
• Low recovery ratio, normally < 50 %
• Not intend to cause surface subsidence
– Development with pillar retrieving
• Pillars are partially recovered
• Higher recovery ratio
• Normally cause immediate surface subsidence
– Traditional (Drill, blast, load and haul operations) almost none now
– Continuous miner (Miner = cut and load, hauling remains to be only non‐continuous operation)

Longwall Panel Development
• Primary support are roof bolts which are installed on cycle during development

24National Energy Technology Laboratory
Longwall Panel Development
• Roof bolting key to the success of high productive longwall mining
• About 100 million pieces of roof bolts consumed per year in U.S.– Mechanical bolts 40%
– Resin bolts 40%
– Specialty bolts. 20%
• Bolt length– Bolt length: 4 ft (1.2 m) ~ 16 ft (4.9 m)
– Max. bolt length < Mining height.
– If bolt length is longer than mining height, bolt notch or sectioned bolts (normally 4 ft 1) are used.
– Majority are 1.5–2.5 m long.

Underground Coal Mining Methods
• Longwall Mining Method– All equipment becomes larger and more automated
• 40 inches (1.07 m) cutting web
• 1,000‐ton shields
• Wider shield (5.5 ft or 1.68 m)
• 2‐leg shields
• 72 inches (1.83 m) belt conveyors, 6,000 tons/hour capacity
• Batch shield moving system (8–10 shield per one operation)
• Fewer workers in one crew (5–6 persons per shift)– 2 shearer operators– 1 shield operator– 1 headgate operator– 1 mechanic – 1 helper (optional)

Longwall Mines
• Daily advance rate– Range: 15–35 m/day
– Average: 23 m/day
• Daily production: 18,000 tons (4 million tons/year)
• Main reasons– Favorite conditions for longwall mining: inclination <5o, height most
between 1.4 ~ 2.1 m
– Relatively shallow overburden: average about 240 m
– Low gassy mines
– Normally single seam mining
– Equipment automation
– Mixing of room & pillar and longwall mining methods: Longwall in good areas and R & P in left‐over areas.

Mountain Top Mining
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining that involves the mining of the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams.

Coal Preparation
Modern coal processing plants incorporate a complex array of solid‐solid and solid liquid separation processes.
• The processes remove unwanted impurities such as ash, sulfur, and moisture from run‐of‐mine (that is, unprocessed coal) feedstocks to improve coal utilization properties.
• Separation technologies used by the coal industry include screening, classification, dense medium separation, gravity concentration, froth flotation, centrifugation, filtration, and thickening.

Central Appalachia Coal Exports
• Global markets have weakened
– Lower‐than‐expected Chinese coal imports
• Supply has increased
– Expanded production in Australia and Indonesia
• As the “swing supplier” in international coal markets, Central Appalachia exports have fallen dramatically

Tightening Environmental and Safety Regulations
• Environmental regulations have tightened on both producers and consumers of coal
– Power plant emissions
– MSHA safety regulations following 2010 UBB disaster
– Valley fill permitting
– Water treatment costs
• Prospects for additional tightening discourage investments

Summary
• Central Appalachia production has been declining for a long time– This is not a short‐term phenomenon
• The decline in Central Appalachia will continue– Competition from other regions for limited markets will be intense
• Natural gas is taking market share– Short‐term declines have been dramatic
• Environmental regulations are taking away domestic markets– Closing power plants
– Forcing scrubbing that reduces demand for lower sulfur coal
• Mining regulations are increasing production costs• Export markets are declining
