摘要
针对断层构造处围岩难以控制问题,采用数值模拟、理论分析及现场实测等方法,分析了断层构造处矿压显现规律及围岩控制措施。现场实测表明,总体上巷道变形在允许范围以内,不影响安全和生产,超前支护取得了良好的支护效果。
Aiming at the problem that surrounding rock is difficult to control at the fault structure, numerical simulation, theoretical analysis and in-situ monitoring were carried out for analyzing the mine pressure behave law at the fault structure and the control measures of surrounding rock. In-situ monitoring shows that the overall deformation of roadway is within the scope of the permit, which ensures the safety production, advanced support has obtained the good effect.
