大松动圈软岩巷道围岩碎胀变形明显,一般的刚性支护难以适应,根据围岩松动圈支护理论利用锚喷网组合拱支护机理解决此类巷道支护问题,曾在我国的淮南、淮北、徐州、开滦等矿区应用获得成功,取得了巨大的经济和社会效益。本文介绍了淮南潘集三号矿井软岩巷道锚喷网支护的参数确定、变形监测与支护效果。此外还简略介绍了淮北石台矿二水平井底车场;平顶山六矿二水平暗斜井;潞安矿务局常村矿过陷落柱等软岩支护成功的经验。
Large loose moving rock tunnel soft rock roadway deformation of the expansion of the obvious, the general rigid support is difficult to adapt, according to the theory of surrounding rock loose ring supporting the use of combined anchor and shotcreting arch support mechanism to solve such roadway support problems, once in our country Huainan, Huaibei, Xuzhou, Kailuan Mining applications such as success, has made tremendous economic and social benefits. This paper introduces the parameter determination, deformation monitoring and supporting effect of the anchor net support in the soft rock roadway of the Panji No.3 Mine in Huainan. In addition, it also briefly introduces the successful experiences of soft rock support such as the subsidence column of the second horizontal well in Shitai Mine of Huaibei;
