摘　　要：针对某铅锌矿存在的问题,以预期达到的损失贫化指标为基础,反算出采矿场各部分的矿量。然后运用Barton的经验评价法评估出采场的无支护安全跨度,进而确定了采矿场参数。并用工程力学方法检验了优化后的采场参数,对不稳定顶板采用锚索加固以达到采场安全稳定要求。According to the problems existing in a lead-zinc ore mine, the masses of each part of the stope are calculated based on the expected loss ratio and dilution ratio. The span without support is evaluated by Barton＇s theory. Thereby the stope parameters are determined. The optimized parameters are analyzed by engineering mechanics. The rock roof should be strengthened with cables so as to meet the requirements of stope safety.
