摘要
通过对马路坪矿深部软岩巷道围岩变形的力学分析,根据对巷道变形破坏范围的分析、计算,得到巷道破坏的相关力学参数,从而得到锚杆支护的长度及支护参数,为深部软岩巷道的支护提拱了依据。
The surrounding rocks occurred in expansive deformation and failure with the increase of excavation. The mechanical analysis of deformation of surrounding rocks in the soft rock roadways in Maluping Mine revealed that the width of the sur- rounding rock plastic zone, the width of the crush zone, displacement at the periphery. The factors for support bolt in roadway roof ware obtained, which provides a basis for supporting the deep soft rock roadways.
