深井高应力回采巷道锚索加强支护优化研究

Research of Deep Roadway Cable Reinforced Supporting Parameters Optimization

以某矿北七采区回采巷道为工程背景,针对该回采巷道埋深较深,所受地应力较大等特点,原有的支护参数满足不了当前支护要求。运用理论分析、数值模拟、现场实测等多种方式,对原有的支护体系进行优化,确定出锚索加强支护的最佳参数,结果表明优化后的支护效果良好,有效地控制了回采巷道围岩的变形。

Take the seven mining area in north as the research object,the roadway depth is deep,crustal stress is big,the original support system already does not apply to the mining roadway.Based on the theoretical analysis,numerical simulation and field measurement,the optimum parameters of anchor support are determined by numerical simulation software to simulate the effect of anchor support,show that the optimized support effect is good,and the deformation of the surrounding rock is controlled effectively.
