摘要
采用现场试验和数值计算相结合的方法，研究表面活性剂溶液填塞炮孔降低露天矿爆破尘毒的效果．结果表明，药液爆破与常规爆破相比，爆破尘毒产生量减少50％以上．该技术对减少深凹露无矿内的环境污染具有重要意义．
The composite method of field experiment and numerical calculation is used to study the effect of filling the shot holes with surface-active detergent solution to reduce the explosive gas and dust in open-pit mine. The result shows that the volume of explosive gas and dust can be decreased 50% by using surface-active defergent solution instead of rock cuttings to fill the shot holes. This technique reduces environment pollution in deep open pit mine.
