从许厂煤矿复杂的地质构造入手,分析了复杂地质构造所引起的高应力特征,并结合围岩物理力学特性对巷道围岩变形破坏特点及破坏机理进行了分析,提出了复杂地质构造及高应力条件下软岩巷道的安全支护技术措施.该结果对同类型工程的设计与施工具有重要的参考价值.
Starting from the complicated geological structure of Xuchang Coal Mine, the characteristics of high stress caused by complex geological structure are analyzed. The characteristics of deformation and failure of surrounding rock are analyzed in combination with the physical and mechanical characteristics of surrounding rock. The complicated geological structure and high Technical Measures for Safe Support of Soft Rock Roadway Under Stress Conditions This result has important reference value for the design and construction of similar projects.
