近距离煤层下煤层回采巷道位置优化

Optimization on Mining Roadways Layout in Lower Coal Seam of Close-distance Seams

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。

Taking the minging roadways in lO＂ coal seam 10 - 105 working face in Mttgua Mine as the research baekgrolmd, th~~ optimi- zation of roadway layout in h^wer coal seam was established and the best position of roadway layout was determined by analyzing the characteristics of stress, displacement and plastic zones.
