摘　　要：为确定红岭铅锌矿分段凿岩阶段空场嗣后充填采矿法的合理采场结构参数,采用数值模拟的方式对顶板厚度分别为3 m、5 m、7 m和10 m,采场长度分别为20 m、30 m、40 m和60 m的16种工况进行了研究,对比了顶板厚度为3 m情况下各工况的应力、位移和塑性区分布。结果表明:红岭铅锌矿分段凿岩阶段空场嗣后充填采矿法采场顶板厚度3 m,采场长度35 m时,采场稳定性较好。To determine the reasonable stope structural parameters for the sublevel drilling stage open stope and subsequent filling mining method in Hongling Lead-Zinc Mine,numerical simulation was employed to study 16 different scenarios with roof thicknesses of 3 m,5 m,7 m,and 10 m,and stope lengths of 20 m,30 m,40 m,and 60 m,respectively.The stress,displacement,and plastic zone distribution of each scenario with a roof thickness of 3 m were compared.The results indicate that the stability of the stope in Hongling Lead-Zinc Mine is fairly good when the roof thickness is 3 m and the stope length is 35 m for the sublevel drilling stage open stope and subsequent filling mining method.
