摘要: 以木瓜煤矿10#煤层10-105工作面回采巷道为背景,建立了下煤层中回采巷道位置优化的数值计算模型,对比不同布置方案下巷道围岩应力、位移及塑性区,确定了下煤层中回采巷道布置的最佳位置。Abstract: Taking the minging roadways in 10# coal seam 10-105 working face in Mugua Mine as the research background, the optimization of roadway layout in lower coal seam was established and the best position of roadway layout was determined by analyzing the characteristics of stress, displacement and plastic zones.
