摘　　要：针对金厂河铅锌矿体产状稳定、矿体厚大、倾角缓、品位高、南北倾向短的特点,选择了高阶段大直径深孔侧向崩矿嗣后充填采矿法,同时阐述了该采矿方法的开采工艺。为确保生产过程中该采矿方法安全使用的可靠性及合理性,采用岩土FLAC^(3D)软件对15m宽的条带两步骤回采(一步骤回采矿柱;二步骤回采矿房)进行稳定性分析论证。模拟结果表明:采用隔一采一的方式,每步骤15m宽的条带开挖后,采空区周边围岩出现塑性扰动区较小,整体处于稳定状态,验证了该采矿工艺安全、高效、成本低,具有一定的可行性和合理性,为矿山的安全高效生产提供了理论依据支撑。According to the characteristics of stable occurrence,thick ore body,gentle dip angle,high-garde and short north-south trend of ore body in Jinchanghe Lead-Zinc,the high stage large diameter deep hole side caving and subsequent filling mining method is selected,at the same time,the mining technology of the mining method is described.In order to ensure the reliability and rationality of safe use of the mining method in the production process,the stability analysis and demonstration of 15 m wide strip two-step stoping(one-step stoping pillar,two-step stoping room)is simulated by FLAC^(3D) software.Simulation results show that using the method of mining every other,the plastic disturbance area of surrounding rock around the goaf is small,and the whole area is stable after each 15 m wide-strip has mined,which proves that the mining method has the advantages of safety,high efficiency and low cost,and has certain feasibility and rationality.The research results provide a theoretical basis for the safe and efficient production of the mine.
