2.Coal Development and Infrastructure Survey. The assessment of a coal mine requires a wide range of surveys and analysis, including assessing the quantity of coal resource, mining method, mine design (including coal mining, coal preparation, and transportation), operations design, transportation infrastructure, coal sale planning, and environmental measures.
In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage. Longwall.

Safety and Hazards Dangers to miners. Coal mining is dangerous activity and the list of mining disasters is a long one. In the US alone, more than 100,000 coal miners were killed in accidents in the twentieth century, 90 percent of the fatalities occurring in the first half of the century. More than 3,200 died in 1907 alone. Open cut hazards are principally mine wall failures and vehicle ...

Why is Coal Preparation Need. Raw coal is mixed with various mineral impurities in the process of formation, and inevitably mixed with rocks and other impurities in the roof and floor in the process of mining and transportation. So the raw coal must be prepared, the main purpose of coal preparation can be summarized as follows:
starting with mining coal, washing the coal at a site near the mine, transporting the coal ... This project did not examine the carbon footprints for mining ore or flux; for preparation and transportation of ore and flux; or for any of the downstream operations involved in
surface mine, whereas a much longer time is consumed by transportation in an underground mine because of the typically long distance from the mine entry to the working stope and face. Thus, more net working hours are available at surface mines, which results in higher production rates per employee. Therefore, production rates per
CO 2 is also emitted through the combustion of the fuels that provide the energy for mining operations. 43.6 tons of CO 2 equivalents are emitted from rail transportation, 5.89 tons of CO 2 equivalents from H 2 O transportation, and 69 tons of CO 2 equivalents from truck transportation, for a million ton per miles of coal transported (Green ...
