The prehensive mechanized coal mining is the pletion of coal, coal, coal and roof support and a series of mechanized. The research in the design of the coal seam mining height of m thick coal seam, is more mon, 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 coal mining machine, mining height, the cutting depth, productivity, traction speed, traction, the cutting speed, the installed power. This design uses the MG160\/375W coal mining machine, the shearer is more mon in china. In transportation design selected matching with MG160\/375W SGB764\/320 type conveyor, conveyor and transport capacity and strength of the scraper chain is checked. In the roof support accordi
