摘　　要：针对桃林铅锌矿大爆破中的事故隐患问题,开展了挤压爆破研究,确定了适应该矿矿岩条件的挤压爆破参数,并将其应用于工业试验。试验表明,该爆破方法具有工艺简单、作业安全、操作方便,大块率低等优点。试验取得了良好的效果。As potential accidents hazards exist with massive blasting in Taolin lead-zinc mine, experimental study on tight blasting was conducted. Tight blasting parameters suitable for the ore and surrounding rock conditions were determined and put to use in industial tests. The results indicated that tight blasting method has following advantages; simple technique, safe wosking, convenient operation, low oversize piece rate. The experimental study achieved good results.
