摘要
以朱集西矿-960 m水平西翼软岩巷道群为工程背景,基于理论分析与数值计算,揭示了不同侧压力系数条件下煤矸石运输大巷与回风大巷开挖对既有邻近轨道运输大巷围岩塑性区、变形场和应力场的扰动影响规律。
Taking soft rock roadways in west side of -960 m level of Zhujixi mine as the engineering background, based on theoretical analysis and numerical calculation, the influence law of plastic zone, deformation field and stress field of rail transport alleys disturbed by excavating nearby coal gangue transport alleys and return air alleys with different lateral pressure coefficient is revealed.
