摘要
通过中深孔小补偿空间挤压爆破的研究,找出大红山铜矿一期大块产出的原因,改进爆破工艺,降低大块率,提高爆破质量。
Based on the research on colooision blasting of small compensation space, the cause of boulder t the first stage of the first stage of Dahongshan Copper Mine is found out, so as to take measures for improve the blast technique , cut down the boulder frequency and improve the quality of blasting.
