摘要
在高应力不良岩层中巷道有效支护类型选择是一个重要课题。论文对大量的现场实测数据进行了归纳分析,提出了合理选择断面形状、适时封底以及运用网构钢拱架等技术措施,使巷道达到安全、经济。
On the basis of experimcnts and comparisons,this.paper determines the rea-sonable suopporting technology in the poor strata of high stress area, anaiyses and concludes numerous prctical data,then puts forward the measurements of ehoosing reasonable see-tional shape and using net-steel asrched-support, so as to make the roadway more sa ery and more economic.
