影响空气冲击波释放的可控因素是装药重量、炮孔直径、抵抗线、堵塞高度和爆炸定向 | controllable factors that affect airblast emission include charge weight, hole diameter, burden, stemming height and blast orientation |
炮孔底部线装药密度炮孔底部单位长度装药量,单位为kg/m | linear charge concentration at the bottom of the blasthole |
炮孔药柱线装药密度炮孔中装药部分的单位长度的药量,单位为 kg/m | linear charge concentration in the column of the blasthole |
由于造价降低幅度大、用震动管代替装有雷管的导火线点火索则名正言顺 | Costs fell to a level which made it justifiable to replace capped fuse-igniter cords with shock tubes |
线型装药在控制边界爆破或拆除爆破中采用的装药形式,指炸药按线延伸状进行装载,参见 string loading | linear shaped charge |
线形药卷装药 | string load stick powder |
线形装药在控制边界爆破或拆除爆破中采用的装药形式,系指炸药按线延伸状进行装载。这种情况下,药包直径要比炮孔直径小,而又不填炮泥。参见 linear shaped charge | string loading |
线性集中装药 | linear concentration of charge |
线装药密度炮孔单位长度方向上的装药量,其单位为 kg/m | linear charge concentration |
装药线密度每米钻孔的装药量,单位为 kg/m | charge concentration linear |
调查结果表明、飞石事故是由以下一个以上的因素促成的: 地质及岩石结构的非连续性、炮孔布置和装药量不适当、抵抗线不足、炸药能量高度集中、填塞不足 | Investigations of flyrock accidents have revealed one or more of the following contributing factors: I discontinuity in the geology and rock structure,II improper blast hole layout and loading, III insufficient burden, IV very high explosive concentration, and V inadequate stemming |
