摘要
作者仅以其近几年的工作经验 ,结合石灰石矿的特点 ,分析研究了影响龙门山矿中深孔爆破质量的各种因素。这些因素主要是矿山地质条件、穿爆参数 ;起爆药包位置、装药结构、起爆顺序、微差间隔时间、炸药性质等。在上述研究的基础上 。
On the base of their working experience over the years and in the light of the features of limestone mines,authors studies various factors of influencing the quality of blasting with medium length holes These factors are geological and mining conditions,drilling and blasting parameters,primer position,charging structure,blasting sequence,millisecond delay interval,explosive characteristics and others On the base of the above study,the technological measures for elimination or weakening of the unfavorable impact of these factors are put forward
