摘　　要：分析了倾斜薄矿脉矿山房柱法开采时的人工矿柱承载机理,并推导了人工矿柱相关参数的计算公式。以南方某铀矿采场为例,对其人工矿柱的规格、数量、混凝土消耗量等参数进行了计算、分析,优化选取了人工矿柱参数。并以此对采场回采工作进行了数值模拟研究,验证其开采的安全性,并提出矿柱参数进一步优化的方向。The bearing mechanism of the pillars in the inclined thin vein by adopting room-and-pillars mining method was analyzed,and the computational formulas for pillars relevant parameters was deduced.Taking a stope in southern province for example,the pillars’size,quantity,concrete consumption etc.parameters were calculated and analyzed.Optimizing choice of artificial pillar parameter was made.Furthermore,numerical modeling study for the stope backstopping process was carried on the parameters,which verified the security during mining.And artificial pillar parameter further optimizing direction was proposed.
