以淮南张集煤矿1722(1)运顺外段为背景,分析富水泥化巷道支护失效工程地质诱因,采用数值模拟方法对富水泥化巷道支护失效进行分析,得出原有常规锚网索支护存在垮冒隐患,需进行支护参数优化。继而提出2种优化补强加固支护方案。
Taking the outlying sections of 1722 (1) Yun-shun coal mine in Zhangji coal mine of Huainan as the background, the engineering geologic inducement of the roadway with rich cementing is analyzed and the numerical simulation is used to analyze the failure of cement-rich roadway. The results show that the original conventional anchor net Cable support there is a risk of collapse, the need for support parameters optimization. Then proposed two kinds of optimization reinforcement reinforcement support program.
