季节冻层穿孔爆破参数的确定及效果分析

Determination of Boring Parameters in Season Freezed Layer and Analysis on Its Blasting Effects

根据寒冷地区露天矿开采对季节冻层穿孔爆破特点,结合伊敏露天矿冬季开采,对季节冻层爆破效果进行了较为全面的分析和采取了相应措施,提出季节冻层爆破时采用的穿爆参数。

According to the characters of boring hole in season freezed layer of the opencut exploiting in chilly regions, combined with the exploitation in winter of Yimin mine,the blasting effects of the season freezing layer blasting are analyzed and the corresponding measures are taken, also parameters of the season freezing layer blasting are put forward, it may have directive significance in practice.
