Mechanized coal mining is completed off the coal, and installed a series of mechanized general term of the coal, coal and roof support. Mining height of 2.9 m thick coal seam, the coal seams studied in this design is more common, so the selection is relatively easy, Shearer choice of models mainly based on coal seam hardness, thickness, angle select, selection also calculate the main parameters of the shearer cutting height, cutting depth, productivity, drawing speed, traction and cutting speed, the installed power. This design selected the MG650/1600WD Shearer, the shearer is more common in China. In transport design selected matching with MG650/1600WD SGZ900/1050 type conveyor and conveyor transmission capacity and the strength of the scraper chain checking. Selected in the roof support according to the stability of the roof support shield support, the frame type according to the mining height, resistance, etc. to determine this design in the selection of ZY8600/24/50 type, but also use a more common frame type, but also on the supporting strength checking, determine the total number of face bracket required. Emulsion pump station, this
