摘要
以攀钢兰尖铁矿废石平硐系统为对象 ,采用不同的分析计算方法 ,导出了生产临界爆破药量和距离的关系。
With the waste rock adit system of Lanjian Iron Mine of Panzhihua Steel Co.as the object,various analytic calculation methods were used to work out the relation between the critical explosive dosage and the distance in production.The results of the suggested calculation of the critical speed method have been used in the open pit production of Lanjian Iron Mine.
