The invention provides a method for fully mechanized continuously-filling
coal mining of steeply pitching
coal seams, which comprises the following steps: a
stoping face is arranged as per the method of long-wall mining along the strike, and fully mechanized mining equipment for the steeply pitching
coal seam is adopted; an
air cushion and a working face filling pipeline are arranged on a base on the side of a mined out space of rear pillars of a fully mechanized mining support; whenever the working face advances for every 1.4 to 1.8 meters and after the support is moved, the working face filling pipeline is connected with an upper gateway filling main pipeline; the
air cushion is filled with air, and auxiliary separation is arranged; paste is conveyed to a filling
pipe branch sequentially from low to high so as to ensure filling and compacting, and finally the paste is conveyed to a supplementary filling
pipe of the upper gateway; after the paste is coagulated, a portion of air in the
air cushion is released, and the working face advances forward continuously; the steps are repeated until the stopping work for the whole working face and the filling work for the mined out space are finished. The method provided by the invention is convenient to operate and simple to carry out, can improve the
mechanization level for mining the steeply pitching coal seams under buildings, railways and water bodies, improves the output of the working face, efficiently reduces the roof
subsidence and the ground deformation, and realizes
coal mining without the pillars and achieves Y type ventilation.
