摘要
中国岩金地下开采矿山逐孔起爆技术应用不多。详述了逐孔起爆微差时间间隔和起爆网络的选择及设计,介绍了那林金矿逐孔微差爆破工程试验与实践。试验研究结果表明,中深孔逐孔爆破技术能够有效地降低爆破震动,改善爆破效果和提高爆破的安全性。
The application of hole-by-hole blasting technique is not common in underground gold mining in China.The paper explains the choice and design of time interval and detonating network of hole-by-hole blasting. The industrial experiment and practice of hole-by-hole millisecond blasting in Nalin gold mine is introduced.It is found that the long and medium hole drilling hole-by-hole blasting can reduce the blasting concussion,enhance the blasting effects and safety.
