爆生气体可经过裂缝传播到水平自由面、并产生漏斗效应及随之而来的飞石。飞石表现的这种机理与冲击波的气体释放脉冲密切有关
blast gases can propagate through cracks to the horizontal free surface and cause cratering and associated flyrock. This mechanism of flyrock manifestation is closely related to the gas release pulse
GRP
for airblast
由于对高压气体的过早喷泄进行控制所起的限制作用、飞石飞行距离随炮泥长度的增加而递减的这种趋势是显而易见的
The decreasing trend of flyrock distance with increasing stemming length is obvious from the role of confinement in controlling premature venting of high pressure gases
虽说采矿现场爆炸的实际气体释放量要小一些、但由于气体释放量随着爆炸条件的变化而变化、所以依然是个问题、而且难以准确予以量化
Though of a lesser magnitude, the actual mine site emissions from detonation may be problematic as they could vary according to detonation conditions and are difficult to quantify precisely
