Application of block coal anti-breaking spiral conveyor technology in Xintian Coal Mine
This paper elaborates on the high coal loss rate in Xintian Coal Mine,mainly due to the large original coal drop in the bottom of the mine,which easily leads to the breakage of block coal.In view of the coal quality characteristics and structural features of the bottom coal bin in Xintian Coal Mine,a solution to install anti-breaking spiral conveyors in the bottom coal bin is proposed.The paper introduces the principle of spiral conveyor anti-breaking,and the application effect and technical and economic benefits in Qianjin Coal Mine are described.
