软岩巷道采用树锚网喷与圆拱碹联合支护的可行性分析

Feasibility Analysis of Combined Support with Resin-grouted Roof Bolt and Circular Arch Lining for Soft Rock Roadway

分析了老屋基矿软岩巷道失修的原因,根据软岩岩层的特殊性,对软岩巷道采用一般支护比较困难的情况下,进行树锚网喷与圆拱碹联合支护的可行性分析,从而找到适于软岩巷道支护的方式,解决了软岩巷道支护困难的难题,给矿带来了较好的经济效益。

Analy sis is made in this paper on the cause of disrepair of soft rock road ways in Laowuji Coal Mine,on the basis of the fea-tures of soft rock strata,feasible analysis is also made on the com-bined support of soft rock roadway with resin-grouted roof bolts and cir cular arch lining when the roadway is difficult to be sup-ported by ordinary support pattern,and a support pattern suitable for soft rock road way is found,which thus solve the difficult prob-lems of such road way support and bring better economic benefit for the mine.
