摘要
为研究煤矿深部高应力软岩巷道的控制方法,分析了深部高应力软岩巷道的变形特征和控制机理。研究结果表明,根据不同的工程条件,对高应力软岩巷道实行"对症下药"的锚、网、索、喷联合支护方式是控制高应力软岩巷道的有效途径,并通过对吕家坨矿深部采区巷道的现场工程实践,验证了这种联合支护方案的可行性。
This paper offers an analysis of the deformation features and control mechanism in an effort to study the controlling methods of soft roadway in high stress in deep coal mine. Investigation results show that： depending on different project conditions, practice of subjecting soft roadway in high stress to the proper support, combined with bolt,steel mesh,anchor and shotcrete, proves to be effective, as in the case of the project practice in lv-jia-tuo coal mine.
