摘要
以双鸭山矿业集团东保卫煤矿为例,以火成岩侵入区地质条件下的力学分析为主,对东保卫煤矿火成岩侵入区巷道进行地质力学评估,以获得火成岩侵入区围岩物理力学特性及锚固特性,对矿井原有支护进行优化设计,在保障巷道围岩稳定性的同时,降低巷道支护维护成本。
The Dongbaowei coal mine of Shuangyashan mining group is taken as an example to analyze the mechanics of the igneous intrusion zone. The geomechanical evaluation of the igneous intrusion zone in Dongbaowei coal mine is carried out. The optimize support scheme, while ensuring the stability of the surrounding rock, reducing the maintenance costs of roadway support.
