The Most Common Accidents in the Mining Industry

The yearly average in coal mining decreased to 30 fatalities from 2001-2005 though 60 to 70 miners still die each year in the U S coal and non-coal mining industry The most common accidents occurring in the mining industry are the result of poisonous or explosive gases or mishaps relating to the use of explosives for blasting operations Get price


Hydraulic Stowing

Underground mining methods are used to extract coal from deep coal seams with an average recovery of about 50% of the mineable reserve in a property Thus approximately 50% of the mineable reserve is lost in the mining process In fact in farming areas some additional coal is left in the coal pillars to prevent subsidence of the surface Get price



larly the mining plan would avoid some of the most sensitive areas and linear facility corridors were selected giving consideration to avoiding environmentally sensitive areas Unavoidable impacts to wetlands would require compensatory mitigation Additional measures would be incorporated at subsequent stages of design and engi-neering Get price
