摘要
基于巷道支护难题,探寻随着开采深度加大巷道矿压显现明显,支护难度较大,巷道支护效果差的原因,通过对不同岩层的岩石的物理力学特性测试、制定围岩破碎破碎程度的评价标准以及对围岩的原岩应力现场测试,研究产生这种现象的机理,基于研究所取得的成果,为以后研究深部开采巷道支护形式及参数奠定基础,提供科学的依据,进而为提出适合于深部开采巷道支护的形式和参数奠定基础。
Based on the difficult problem of roadway support,explores the reasons why the roadway pressure appears obviously,the support is difficult and the support effect is poor with the increase of mining depth. By testing the physical and mechanical properties of rocks in different strata,formulating the evaluation criteria for the degree of broken surrounding rocks and testing the original rock stress of surrounding rocks in situ,the mechanism of this phenomenon is studied. The results lay a foundation for further research on the supporting forms and parameters of deep mining roadways,and provide a scientific basis,and then put forward the supporting forms and parameters suitable for deep mining roadways.
