Thin seam coal mine blast mining of coal block specific products, block board is to block coal, when coal blasting off toward the direction of coal gob device, which is installed in the conveyor chute near the gob side of the retaining tube rack, when the burst toward the coal drop at the time of the coal mined areas within the block away in the scraper conveyor, automatic loading of area after the coal, coal block off plate for coal mine blast mining. Board's role is to block coal block blasting coal gob when the direction toward the coal, coal block to withstand the blast plate moment a large impact, so the board asked both coal block coal block, and can not produce plastic deformation; while must have easy to operate, easy to replace. Reduce labor intensity and improve coal recovery. 
 Significantly improved recovery of floating coal face, floating coal recovery rate from 91% to 97%, reducing the resources lost, so much less investment and output, reduce labor intensity of workers, economic efficiency has improved significantly.
