露天矿山台阶爆破降震研究

Research on Vibration Reduction of Bench Blasting in Open-pit Mine

通过露天矿山台阶爆破震动测试研究,找出露天矿山不同地点不同矿岩中爆破规模、最大一段装药量及总药量与爆破震动效应强弱之间的一般关系,为确定露天矿山不同地点不同矿岩中合理的爆破规模、最大一段装药量及总药量,优化爆破技术参数提供参考依据。

Through test research on the blasting vibration of open-pit mine,the general relationship between the blasting scale,the maximum one-stage charge and total charge of different ore-bearing rocks at different location of open-pit mine and the intensity of blasting vibration effect is found out.It provides reference for determining the reasonable blasting scale,maximum one-stage charge and total charge of different ore-bearing rocks at different location of open-pit mine and for optimizing technical parameters of the blasting.
