摘　　要：简述了大直径深孔爆破技术在云锡卡房Ⅰ-26-1#矿体坚硬矿岩条件下的应用。针对试采过程中大块率高的问题,通过现场调查和分析找出了大块产生的根本原因;总结和提出了控制大块率的有效措施,解决了制约卡房钨多金属生产基地达产达标的瓶颈问题。The application of large-diameter longhole blasting technology for hard rock at oreⅠ-26-1^#in Kafang mine was briefly described.Aiming at high boulder yield during production test,primary causes were disclosed by fieldwork and analysis.Furthermore,effective measures for reducing boulder yield were proposed,which solved the bottleneck problems of restricting the mining production up to the standard in Kafang mine.
