【摘要】 矿柱的安全回采及采空区处理直接关系到矿山的可持续发展与人员的安全。以内蒙古某矿区铁锌多金属矿山工程地质为依据,采用超声波测试技术,探测多次爆破下回采巷道围岩损伤累计增长规律,通过尾砂胶结物充填技术,以FLAC3D模拟巷道围岩在外界荷载作用下的受力情况,主要是应力、应变及变形位移量的分析,对矿山安全回采方面具有较为重要的理论意义和工程应用价值。更多还原

【Abstract】 The pillar safety mining and goaf processing directly related to the sustainable development of mining and the safety of the staff.Based on the engineering geology of multi-metal mine of a mining area,the ultrasonic testing technology,exploration of many times under the surrounding rock blasting mining damage cumulative growth rule,the mechanical deformation of the surrounding rock under external loading condition is simulated by FLAC3D,mainly is the stress,strain and deformation of the displacement analysis of mine safety mining.The results have an important theoretical significance and application value.更多还原
