| 摘 要： | 通过对赵家坝煤矿急倾斜煤层群开采方案的比较,选定了联合开采的巷道布置方案;通过理论分析、现场实测和模拟计算,确定了联合开采顺序、采煤方法以及不同煤层与不同区段间的合理错距。生产实践证明联合开采有利于安全和提高经济效益,该结论对类似条件下巷道布置设计、采煤方法选择有参考意义。

| Abstract: | Zhaojiaba coal mine is located in Wangchang county,Sichuan province. It is a small-size coal mine with production capacity of 300 kt/a. After comparing mining options in steep inclined thin seam group at Zhaojiaba coal mine,the roadway layout of combined mining is selected. The mining procedure,mining methods,and reasonable malposition under different seams and different mining sections are studied by theoretical analysis, in-situ measurement and numerical calculation. The practices show that the roadway layout of combined mining is safe and economical benefit can be improved. The results of the practice are referable to the design of roadway layout and mining method with similar conditions. |
