摘要
Abstract
The common phenomenon of ectopic holes blasting in the process of blasting work in the open pit,leads to the undesirable subsequent blasting working effect,such as higher rate of blocky ore,high explosives consumption,and abundant residuals.To solve these problems,this paper,taking FuShun east open pit mine as an example,based on the practical blasting parameters,simulated it with the finite element software of ANSYS/LS-DYNA,fitted the numerical simulation result with the least square method,the matching formula of each hole is obtained,and then the best matching relation between the hole diameter and the hole charge is found.This study provides theoretical guidance to cost control of drilling and blasting production and engineering blasting.关键词
