本文通过分析冻土层爆破后形成结冻大块的诸多因素,提出冻土层爆破技术方案,并成功实施爆破,改善了铲装条件,杜绝了在结土层地带爆破后的铲装过程中发生大冻块砸铲事故,节约了剥采成本,提高了铲装效率。
In this paper, by analyzing many factors that lead to the formation of frozen chunks after permafrost blasting, a scheme of blasting technology in permafrost layers is put forward and blasting is successfully carried out to improve the shovel loading conditions and eliminate the need for blasting in the soil layer after blasting A large block of frozen shovel accident occurred, saving the stripping costs, improve shovel efficiency.
