摘要
金厂峪金矿采矿方法以浅孔留矿法为主,为了解决上向眼落矿的安全问题,进行了平立交替爆破和平立交替控制爆破落矿的试验与实践,取得了很好的效果.
Short-hole shrinkage is the main mining method of Jin-Chang-yu Gold Mine. In order to deal with the safety problems during blasting in vertical drill holes, horizontal-and-vertical alternative blasting and horizontal-and-vertical alternative controlled blasting were tested and practised, and good results achieved.
