煤矿深井巷道锚网支护体系研究与应用

Research and Application of Bolt-net Support System for Deep Mine Roadway in Coal Mine

在我国煤矿生产建设过程中,软岩巷道围岩控制技术成了影响且制约着煤矿的生产建设的重大性技术问题之一。城郊煤矿产量高,现阶段采掘接替比较紧张,为合理解决深部因为地质构造、埋深等的影响造成应力增大及因为采矿扰动而给软岩巷道的稳定性造成影响的问题,因此研究了深部高应力软岩巷道的变形破坏具有的特征,寻求合理的支护方式,进而保证城郊煤矿的安全生产。以城郊煤矿为例,对深井强矿压弱结构围岩巷道锚网支护体系的机理与应用进行了分析。

In the process of coal mine production and construction in China,the surrounding rock control technology of soft rock roadway has become one of the major technical issues affecting and restricting the production and construction of coal mines. The suburban coal mine has a high output,and the mining replacement is relatively tense at this stage. In order to reasonably solve the problem of deepening the stress caused by the geological structure and the buried depth in the deep,and the impact of the mining disturbance on the stability of the soft rock roadway,the research to understand the characteristics of deformation and failure of deep high-stress soft rock roadways,a reasonable support method is sought to ensure the safe production of suburban coal mines. In this paper,taking the suburban coal mine as an example,the mechanism and application of the anchor-net support system of the surrounding rock roadway in a deep mine with strong mine pressure structure are analyzed.
