深孔药壶爆破中的安全问题

Safety in Deep-Hole Chamber Springing Blasts

根据深孔药壶爆破中存在的主要安全问题 ,从设计和施工两方面分别提出了深孔药壶爆破法最小爆扩安全间距的校核方法和施工中应严格控制的几个钻孔参数 ,对减少了壶腔坍塌或贯通而可能带来的事故隐患、提高深孔药壶法爆破施工的安全性具有重要意义。

Based on the authors' study of modern blasting theory and experimental results,the paper puts forward respectirely methods to cheek the minimum safe distance of deep-hole chamber springing blasts from two aspects such as design and construction. It presents also some key drilling parameters. The application of the above methods can prevent the collapse of linking up of adjacent cavities so as to be able to heighten the safety of deep-hole springing blasts.
