dec 22, 2012 coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.it is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the united states.the means of gaining access to the coal seam from the surface is a matter to be decided early in the planning process and which can greatly affect the future operations for the whole life of the mine. decisions need to be made regarding the: type and function number; size

the US coal mine health and safety act became a law in 1969, establishing an enforceable federal limit on the exposure of underground miners to respirable coal mine dust. the goal of the act was to prevent the severe and lethal forms of pneumoconiosis that were prevalent at that time among coal miners in the united states. It was acknowledged that the exposure limit would not fully protect thick underground coal great deal of the nations coal resources are located in the west and are characterized by thick seams under deep cover. although significant tonnages of this coal may not be needed for years, important long-term research concerns underground mining of this coal.
underground coal gasification takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. the main difference is that in ucg the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface.1 obviously gases reaching the earths surface from the underground coal fire at centralia, pa, usa, which has been burning since 1962. As miners removed coal from deep mines, pillars of the coal were left to hold up the rocks above. the fire has burned these pillars away, allowing collapses that have broken up the earths surface, as shown here.

when the 1969 coal mine health and safety act was enacted, u.s. coal production was about 600 million tons with about percent underground mining and percent surface mining. longwall mining accounted for less than percent of the underground production; room-and-pillar continuous mining accounted for about percent of the underground In this study, accident records of underground coal mines of cherat coal field were collected and analysis was carried out to understand the consequences, time of occurrence and causes of accidents.
