大兴公司开采的2煤、3煤具有强粘结性,主井卸载煤仓漏斗极易发生堵仓现象,频繁的堵仓问题既影响原煤的提升,又影响采煤工作面的正常正常生产等。通过在卸载仓安装"空气炮",解决了皮带运输系统的瓶颈问题,取得了良好的效果。
NO.2, NO.3 coal seam in DaXing coal company has the strong adhesion, unloading bunker of the main shaft is prone to blocking, which not only affects the coal lifting, aslo affect the normal production , Through the installation of "air cannon" in the unloading bunker, the bottleneck problem of the belt conveyor system is solved, and obtained good results.
