大梁铅锌矿Ⅰ＃矿体中深孔爆破参数优化研究

摘要

针对矿山现有爆破效果大块率高等现象，通过分析其产生的原因，采取了大孔距小抵抗线等改进措施，适时地改变了爆破参数，改进了爆破工艺及爆破条件，获得了良好的爆破效果，为矿山创造了良好的经济效益和社会效益。%Aiming at the phenomenon of the blasting effect of the higher block rate,by means of analysis of its causes,it takes the improvement measures of the big hole pitch and small resistance,timely changes the blasting parameters,and improves blasting technology and blasting conditions,which has obtained the good blasting effect and created a good economic benefit and social benefit for the mine.
