110工法巷帮支护及矿压显现规律研究

Study on the Law of Support and Strata Behavior of 110 Methods

本文以店坪煤矿110工法沿空留巷工作面为工程背景,对留巷期间巷帮挡矸措施,支护体受力状态以及侧向挡矸压力进行了研究,工程实践表明,采用U型钢可缩支架与单体间隔布置的方式,可以有效阻止矸石进入巷道,保证留巷效果。

In this paper, the working face of the roadway along the roadway in the Shangping Coal Mine is studied. The engineering practice shows that the method of retaining the gangue, the supporting force and the lateral gangue pressure during the stay of the roadway are studied. U-shaped steel retractable bracket and the arrangement of the single way, can effectively prevent the gangue into the roadway, to ensure the effect of retaining the road.
