摘要
山西沁水煤田整体地质构造复杂,褶曲、陷落柱及断层极为发育,给矿井的安全生产带来较大的威胁。为了提高巷道掘进效率,该矿采用复合型顶板支护方式,改善巷道顶板支护的可靠性,减少巷道后期修复成本,优化矿井经济效益。
The overall geological structure of Qinshui coalfield in Shanxi Province is complex,with the development of folds,collapse columns and faults,which poses a great threat to the safety production of the mine.In order to improve the efficiency of roadway excavation,the mine adopts composite roof support mode to improve the reliability of roadway roof support,reduce the cost of roadway repair in the later stage,and optimize the economic benefits of the mine.
