摘要
通过对四台矿12号煤层回采工作面沿空巷道上覆围岩结构稳定性分析研究,为改善沿空巷道的维护、设计及选用合理的支护方式提供了理论方向和实践依据,对进一步提高煤层回采率具有重要的指导意义。
based on the 12th in Sitai mine coal seam working face along the empty overlying structure stability analysis of surrounding rock of roadway,to improve along goaf roadway maintenance,design and choose rational support method provides theoretical direction and practical basis,to further improve the recovery rate of coal seam has important guiding significance.
