Sampling and analysis method for measuring airborne coal

Sampling and analysis method for measuring airborne coal

Mixtures of known coal and limestone dust masses were prepared in the laboratory, loaded into the stainless steel cassettes, and analyzed to assess the accuracy of this method. Coal dust mass measurements differed from predicted values by an average of 0.5%, 0.2%, and 0.1% for samples containing 20%, 91%, and 95% limestone dust, respectively.

Longwall mining introduces methane into the mine through collapse of the roof and floor or where conduits within the subsurface provide a transport path way for methane into the mine. To differentiate from CMM, gas in non-coal mines is sometimes referred to as waste mine methane.

Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100 C in the absence of oxygen for 12-36 hours.
