王庄煤矿采区煤柱工作面回采技术研究

Wangzhuang a Mining Area Coal Pillar Mining Face Technology Research

王庄煤矿面临着生产系统庞大而可采储量少的困境,针对这一问题,通过对该矿煤柱工作面回采技术研究,进行煤柱工作面的回采与布置,提高了该矿井的资源采出率,延长了服务年限,实现了旧采区的收尾封区和简化矿井生产系统。

Wangzhuang coal mine was facing huge production system and the plight of the less recoverable reserves, in order to solve this problem, based on the mine working face coal pillar mining technology research, the working face in coal pillar stoping and layout was carried out to improve the mine resource extraction rate, prolong the service life, realize the end seal area of old mining area and simplify the mine production system.
