Key technologies and equipment for a fully mechanized coal mines, which accounts for 44 % of the total minable coal reserve. A fully mechanized topcoal caving mining method is a main underground coal extraction method for ultrathick coal seams. The coal extraction technologies for coal seams less than 14 m thick were extensively used in China.CHAPTER V MINING METHODS AND COAL PROCESSING Inclination of coal seam is the main parameter for determining the type of wall face of mining stopes. Therefore, for extraction of coal reverse benching method is employed for extraction of coal from seams having dip more than 40 degrees whereas longwall mining method is selected for seams with less than 40 degree dip.
Coal Mining Methods EMFIOther underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.Storage of Coal: Problems and Precautions EOLSSMethods of Coal Stacking 2.1 Windrow Method 2.2 Chevron Method 2.3 Cone Shell Type Method 3.
