根据泉店煤矿深部开采的地质条件,针对位于断层构造带的高应力软岩巷道的变形破坏特征,并采用实验室理论分析方法深入研究了在断层构造影响下高应力软岩巷道支护承载结构失稳破坏原因,研究提出新型高强稳定型支护技术。此技术采用带梁锚索对高强锚网支护承载结构进行结构补偿,以提高承载结构的承载能力和结构稳定性。该技术在现场进行了工业性试验,成功应用于泉店煤矿巷道支护实践。
According to the geological conditions of deep mining in Quandian Coal Mine, aiming at the deformation and failure characteristics of high stress and soft rock roadway located in fault structure zone, and using the laboratory theoretical analysis method, the bearing and supporting structure of high stress and soft rock roadway under the influence of fault structure Instability damage, research proposed a new high-strength and stable support technology. In this technology, the structure of the high-strength anchor net support and bearing structure is compensated by using the cable anchor in order to improve the bearing capacity and structural stability of the bearing structure. The technology in the field conducted an industrial test, successfully applied in quarry coal mine roadway support practice.
