铜坑矿井下大爆破地震和冲击灾害的预防与控制

Prevention and Control of Vibration and Shock Wave Damages Caused by Underground Large Blasting in Tongken Mine

简述了铜坑矿井下大爆破地震和冲击灾害预防与控制的实践经验,通过爆破震动试验,可实现对爆破地震和冲击有害效应较准确的预测,依此采取相应的预防与控制措施,达到了确保主要井巷、底部出矿结构及通风、供电等系统设施的完好,高效地回收矿产资源的目的。

The practical experiences of the prevention and control of vibration and shock wave damages caused by underground large blasting in Tongken Mine are briefly, recounted in this paper. Through the test of blasting vibration, the exact prediction of blasting vibration and shock wave damages were realized. Based on the predicted results, the corresponding preventing and controlling measures of blasting vibration and shock wave was adopted, the aims to ensure the system facilities intact （such as the main wells and drifts, bottom structure for ore drawing, ventilation and power supply facilities, etc. ） and high - effectually mining mineral resources were achieved.
