| 摘 要： | 为获取驰宏下属某铅锌矿准确的爆破抵抗线参数,在该矿深部进行了45°和30°斜面台阶爆破漏斗实验,测量了爆破实验数据。根据实验数据和斜面台阶爆破漏斗轮廓线,分析得出炮孔最大抵抗线为0.66 m。实验结果将对优化该铅锌矿深部开采的爆破参数具有实际指导意义。

| Abstract: | In order to obtain the accurate blasting burden for the deep mining of a Chihong lead-zinc mine, two experiments of blasting crater with gradient bench 45° and 30° were carried out. According to the experimental data and the blasting crater curves, the max blasting burden is prescribed with 0.66 m. The experiments provide effective technical support for deep mining of the lead-zinc mine. |
