Commonly used mining techniques to extract coal ICSC

2018-1-25  Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction. However, many coals extracted by using these two methods need washing in a coal preparation plant.

A fuzzy method for selecting underground coal mining

2012-11-30  One of the crucial decisions affecting productivity of the mine is the mining method selection. Longwall mining is quite common in underground coal mining, and it allows the use of mechanization. As application of mechanization increases, production also increases and the number of workers decreases. Thus, the organization of work is easier, and the number of accidents decreases in the mine.
