小煤柱沿空巷道上覆岩层结构及稳定性分析
|
摘要
针对目前关于综采小煤柱沿空巷道上覆岩层结构及稳定性控制方面存在的问题,在理论分析此类巷道上覆岩层结构模型及特征的基础上,进一步分析了小煤柱沿空巷道上覆岩层结构的稳定性,并结合工程背景进行了实例计算,研究结果对完善沿空巷道煤柱留设具有一定的理论意义。
Aiming at the problems existing in the structure and stability control of overlying strata along the alleyway of fully mechanized small coal pillars, based on the theoretical analysis of the overlying strata structure model and characteristics of such tunnels, the small coal pillars along the empty roadway are further analyzed. The stability of the overlying strata structure is combined with the engineering background. The research results have certain theoretical significance for improving the coal pillar retaining along the goaf.
