摘要
为解决王庄煤矿3~#煤开采采掘衔接紧张的问题,提高煤层的资源回收率,降低煤炭生产成本,提高矿井综合效益,提出了沿空留墙无煤柱开采的技术原理.通过对该技术的理论分析,结合3503工作面的开采条件,制定了具体的支护设计方案,并在现场进行了工程应用,取得了令人满意的技术经济效果.该技术为有效解决矿井采掘衔接紧张,避免资源浪费,提供了科学依据,具有良好的推广应用前景.
In order to solve the excavation and mining link tension of 3# coal mining in Wangzhuang Mine, improve the recovery rate of coal mining, reduce production costs, and improve the mine comprehensive benefits, this paper proposes the technology principle of gob-side bricklaying wall mining without pillar. Based on the principle of the theoretical analysis, it formulates the supporting design scheme of concrete by taking the mining condition of 3503 work face into consideration. Finally, the engineering application in the field has achieved the satisfactorily technical and economical effect. The technology has provided a scientific basis for effective solution to the excavation and mining link tension, which can avoid waste of resource and have a good prospect of popularization and application.
