摘要(Abstract)：

针对会泽铅锌矿因浅部资源日益枯竭,逐步向深部开采需要获得准确爆破参数的情况,根据利文斯顿爆破漏斗理论,在会泽铅锌矿深部巷道进行了一系列单孔爆破漏斗实验,得到了爆破漏斗临界埋深为1.21m,最佳埋深为0.6m,最佳爆破漏斗体积为0.153m³,最佳埋深比为0.495 9,应变能系数为1.807 5m/kg3,最佳埋深比为0.495 9,应变能系数为1.807 5m/kg^(1/3)等技术参数。爆破漏斗实验是爆破设计和施工的重要技术手段,是获取岩体爆破准确参数的有效途径,其实验结果为会泽铅锌矿深部开采提供了有效的技术支撑。
Since the mineral resources in shallow of Hui-ze lead-zinc mine are exhausted for the time being,it turns to deep mining gradually.In order to obtain the accurate blasting parameters for the deep mining of Hui-ze lead-zinc mine,a series of single-hole blasting crater experiments were carried out with Livingston's blasting crater theory.The experimental results showed that the critical depth was 1.21 m,the optimum depth was 0.6m,the optimum volume was 0.153m(1/3)等技术参数。爆破漏斗实验是爆破设计和施工的重要技术手段,是获取岩体爆破准确参数的有效途径,其实验结果为会泽铅锌矿深部开采提供了有效的技术支撑。
