摘要
从复杂应力极软岩巷道支护机理与支护体系入手,着力于改善围岩结构及其物理力学性质,适时、随机加固围岩,达到不断提高围岩本身的承载能力;构建均质的支护"圈体"技术,解决深井矿井受复杂应力软岩巷道支护的技术难题。在工程实践中,有效地控制了深井软岩巷道,改善了矿井安全状况,建立安全高效的生产环境。
In order to solve the difficult problem of supporting soft-rock roadway with complex stress in deep mine,following methods were put forward including improving structure of surrounding rock and its physical and mechanical property,reinforcing surrounding rock to improve its loaded ability and constructing homogeneous supporting circle.Practice showed that these methods controlled effectively soft-rock roadway in deep mine and improved safety environment.
