严寒气候对露天矿山安全爆破影响的分析

ANALYSIS ON INFLUENCE OF COLD CLIMATE ON BLASTING SAFETY OF SURFACE MINE

我国现有露天煤矿很大一部分位于内蒙古中北严寒干燥地区,受寒冷气候影响,露天矿山爆破作业遇到诸多困难。针对实际爆破中遇到的一些常见问题,诸如炸药性能、水结冰、冻土、爆破振动等进行理论分析,并结合矿山实际工作者的经验,提出了相应的解决措施,最大限度地改善严寒气候对露天矿爆破造成的负面影响。

A large part of the existing where is very cold and dry. Affected b mine. Common problems were analyzed surface mines are in the northern y cold climate, many difficulties th soil, blasting vibration and so on during th titioners, some appropriate solutions were mate on blasting of surface mine. Region of Inner Mongolia China, appeared to blasting of surface eoretieally such as explosive performance, frozen water, frozen e blasting practice. Combined with the experience of many pracproposed to improve furthest the negative impact of the cold climate on blasting of surface mine.
