前言在露天矿台阶上进行多排深孔毫秒爆破时,炮孔的合理起爆参数是由炮孔布置及起爆顺序决定的,合理的起爆参数将对于炮孔的负担面积赋于合理的形状。首先说明两个概念:其一,炮孔的布置参数是指炮孔相对于采掘线的位置而言,即爆破参数;其二。炮孔起爆参数取决于起爆瞬间炮孔间的相对 Preface In the open pit mine for many rows of deep hole millisecond blasting, the blasting of the reasonable initiation parameters are determined by the blasthole layout and initiation sequence, the reasonable initiation parameters will be boring for the burden area of ​​the hole to a reasonable shape. First of all, two concepts are explained: First, the arrangement parameters of the blasthole are the blasting parameters relative to the position of the blasting line, that is, blasting parameters; Blasting initiation parameters depend on the relative moment between shots
