深孔药壶爆破中药包最小安全间距的研究

Study on the Minimum Safety Distance among Adjacent Charges in Deep Hole Broach Blasting

在实验和实践的基础上 ,利用现代爆破理论 ,提出了深孔药壶爆破法药包最小安全间距的校核方法 ,指出了在深孔药壶爆破实践中应严格控制的几个钻孔参数及孔间距校验方法。它可杜绝相邻壶腔坍塌或贯通可能带来的事故隐患 。

Based on the study of modern blasting theory and experimental results, two checking methods for the minimum safety distance among adjacent charges in deep hole broach blasting are put forward. Some key drilling parameters and hole spacing correction formula are also presented. The application of the above methods can prevent the collapse or link up of adjacent cavities so as to enhance the safety in deep hole broach blasting.
