摘要
根据平朔东露天矿高温爆破孔内部特点,首次将爆破孔分为正常孔、虚量孔和空洞孔。在分析高温孔产生原因的基础上,针对不同钻孔类型提出最适宜的降温技术措施,保证了正常的爆破作业,同时也分析了降温技术的时间效应,对国内露天煤矿处理高温钻孔具有普遍的参考价值和借鉴意义。
According to internal characteristics of blast hole in high temperature in the Pingshuo east open pit mine, blast holes are classified into normal holes, virtual volume holes and void holes for the first time. Based on the analysis of the cause of high temperature holes, the most appropriate cooling technical measures for different types of holes are proposed, ensuring the normal operation of blast. Meanwhile, time effect of cooling technology is analyzed. It has universal referential value and meaning for handling high temperature drilling among domestic open pit mine.
