边排孔位置与爆破飞石距离控制的匹配
Matching the location of side hole and the contral of blasting slungshot distance
摘要
Abstract
In order to effectively control the blasting fly distance and improve the safety of open-pit mine blasting,this paper based on the view point of side deviation hole,analyzed the cause of side deviation hole,described the hole location through offset distance δ,and optimized the blasting effect through adjusting the charge of side hole a and the second side adjacent hole b and c.This study simulated the proposed charge scheme,compared the relative error of stress distribution curve on programs and design hole,and determined the optimal program.Least squares fitting method was used to determine the relationship between explosive charge and offset distance.The research determine the charge quantity of hole a,b and c when the side hole offset distance is δ.This program can effectively improve the safety of blasting.关键词
