Field Experiment of Reducing Explosive Gas and in Deep Open Pit Mine
-
摘要: 采用現場試驗和數值計算相結合的方法,研究表面活性劑溶液填塞炮孔降低露天礦爆破塵毒的效果.結果表明,藥液爆破與常規爆破相比,爆破塵毒產生量減少50%以上.該技術對減少深凹露無礦內的環境污染具有重要意義.Abstract: The composite method of field experiment and numerical calculation is used to study the effect of filling the shot holes with surface-active detergent solution to reduce the explosive gas and dust in open-pit mine. The result shows that the volume of explosive gas and dust can be decreased 50% by using surface-active defergent solution instead of rock cuttings to fill the shot holes. This technique reduces environment pollution in deep open pit mine.
