掘进工作面支护优化探讨

Discussion on optimization of support in driving face

主要结合工程实际分析了煤巷存在的主要问题,并开展实验室试验活动,确定岩石强度准则,明确其重要力学参数,模拟不同的支护方案,以现场实测数据为基础,提出最优的现场支护方案,以期提高掘进效率,优化煤矿的采掘衔接。

This paper mainly analyzes the main problems existing in the coal roadway in combination with the engineering practice,carries out laboratory test activities,determines the rock strength criterion,defines its important mechanical parameters,simulates different support schemes,and puts forward the optimal site support scheme based on the field measured data,in order to improve the driving efficiency and optimize the mining connection of the coal mine.
