摘要
近年来实践表明,应用宽孔距小抵抗爆破技术能改善岩石破碎质量,降低大块率,减少二次破碎成本。本文介绍了云浮硫铁矿在台阶应用宽孔距小抵抗线爆破技术改善爆破质量,从而降低爆破成本提高经济效益的情况。
Recently, the practice improved that using technique of wide-space small burden blasting can improve the rock crushing, low the big crushing rock rate, reduce the secondary crushing cost. This paper introduced the blasting quality was improved by using technique of wide-space small burden blasting in sidestep of Yunfu pyrite mine. Thereby the blasting cost was cut and economic efficiency was improved.
