摘要:

以山西西河煤矿为背景,运用岩土工程力学分析计算软件FLAC3D,对小窑破坏区围岩的应力场及上覆岩层的冒落情况进行了分析,并在此基础上确定了底板巷道开掘的最优位置,有针对性地提出了巷道的支护方案及特殊条件下的支护措施,为煤层破坏区残采巷道的布置及支护提供了指导,具有重要的理论及现实意义。

Abstract:

Based on the background of Xihe Mine in Shanxi Province, using geotechnical engineering mechanical analysis calculation software FLAC3D, the surrounding rock stress field and the falling condition of the overlying strata in small coal mining broken area were analyzed, and on this basis, the optimum placement for the floor roadway excavation was determined, the roadway support scheme and the roadway support measure in special condition were put forward, successfully guided the floor roadway layout and supporting in coal seam broken area and has important theoretical and practical significance.

Key words: residual mining, floor roadway, roadway layout, roadway support
