以科技创新提高衰老矿井经济效益

摘要

In order to improve the economics contribute rate of aging mine ,vibrating screen was installed at the main transfer point underground to primary sorting raw coal .Lump coal rate was increased by reducing lump coal transfer links ,at the same time coal refuse shunt technology was used in repeated mining face to realize the transportation of coal refuse ,which lowered raw coal ash and achieved the aging mine's economic upgrade again .%提出了在井下主要转载点安装震动筛，对原煤进行初次分拣，通过减少块煤转载环节提高块煤率，同时在复采工作面利用煤矸分流技术，实现煤矸的分运，降低原煤灰分，通过上述措施的实施，实现了衰老矿井经济的再次提升。
