摘要
预裂爆破是金属矿山靠界常用的技术,能够有效减弱围岩的破裂,减弱爆破振动对露天矿山边坡的破坏作用,维护边坡的稳定性。为解决巴润铁矿含水区域预裂爆破效果差这一难题,以现场地质调查和理论分析为基础,开展了巴润铁矿含水区域预裂爆破参数优化研究,得到了较为理想的孔网参数,爆破效果十分理想,保证了边坡的稳定性,为矿山含水区域靠界预裂爆破提供了强有力的支撑。
Pre-splitting blasting is a commonly used technology in metal mine,which can weaken the rupture of surrounding rock,weaken the destructive effect of blasting vibration on the slope of open-pit mine,and maintain the stability of slope.In order to solve the problem of poor effect of pre-splitting blasting in water bearing area of Barun Iron Mine,based on the field geological survey and theoretical analysis,the optimization study of pre-splitting blasting parameters in water bearing area of Barun iron mine is carried out,and the ideal hole network parameters are obtained.The blasting effect is very ideal,which ensures the stability of the slope,and provides strong support for the pre-splitting blasting in the water bearing area of the mine.
