摘要
以校企合作项目"采矿工艺优化试验研究"为依托,通过现场测试,收集大量测试数据和波形信号,并对测试数据运用最小二乘法进行回归分析,得出武山铜矿中深孔爆破振动速度的衰减规律,为该矿山今后确定最大一段起爆药量提供了有力的依据和保障,同时也可为类似地下矿山的设计和施工提供参考。
Based on the support of a program jointly carried out by our university and an enterprise,"Experiment and Research on Optimization of Mining Technology",a lot of measured data and vibration wave signals from field blasting tests are collected and regression on the measured data is carried out by using the least square method.The attenuation law of vibration velocities from blasting with medium-length holes is gotten in Wushan Copper Mine.This will provide powerful basis and safeguard for determining the maximum charge weight per delay interval in this mine.Also,this can provide a reference for the design and implementation of blasting in similar underground mines.
