Abstract：Aiming at frozen soil layer blasting in Yimin Open-pit Mine,the article researches the optimization of blasting parameters combining theoretical analysis, program comparison and field practice. The results show that the average consumption is 0.17 ~ 0.18 kg/m3 in December and January,the average consumption is above 0.21 kg/m3 in February and March,the average consumption is 0.15 kg/m3 in April and May. At the same time,the author appropriately adjusts parameters according to bare time of stepped slope and lithology.
