【摘要】 针对大直径深孔采矿中采场出现的超爆、欠爆情况难以确定的问题。选择某矿山23#、25#采场作为试验场地,使用北京矿冶研究总院自主研发的矿用三维激光扫描仪对23#、25#采场进行现场扫描并进行后续数据分析。数据处理结果表明,矿用三维激光扫描仪非常适合采场爆破效果分析,可以定量给出采场超爆、欠爆尺寸,同时可以为后续二步骤回采爆破设计优化提供数据基础。更多还原

【Abstract】 During the large-diameter longhole mining,it is difficult to determine the overbreak and underbreak situations in the stope. Therefore,this paper chooses stope 23#and stope 25#of a mine as the test sites for scanning with the 3D laser scanner developed by Beijing General Research Institute of Mining & Metallurgy,and then conducts the subsequent data analysis. The result of data processing shows that the 3D laser scanner is suitable for analyzing the blasting effect of stopes,can quantitatively offer the overbreak and underbreak size,and provide data basis for blasting design in the following mining.更多还原
