Terms for subject Explosives and Explosive Ordnance Disposal containing 飞过

Chinese	English
在炸药爆炸过程中、合成能量转化为破岩和位移这些有益的实用能量。振动、冲击波和飞石这些不利的负面效应也是由合成能量产生的	In the detonation of explosives, the resultant energy is converted into beneficial applications such as fragmentation and displacement. It is also responsible for adverse side effects such as vibration, airblast and flyrock
在过去的几十年里、人们对飞石现象进行了大量的实验研究和理论研究	Much experimental and theoretical work about flyrock phenomena has been performed in the past decades
意外飞石的产生、是由于爆破过程或岩体中出现异常、致使破碎岩石出乎意料地飞越爆破禁区之外	Wild flyrock occurs due to the unexpected propulsion of rock fragments,when there is some abnormality in a blast or a rock mass, that travels beyond the blast clearance exclusion zone
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
经过多次实地测试、他们的结论是、如果药量的增加、破碎量和飞石的速度也随之剧增	After repeated field experiments, they drew a conclusion that as the charge increases, the fragmentation and the velocity of the broken material increases as well
飞石产生的主要原因包括抵抗线不足、炮泥长度不够、钻孔不精确、单位炸药消耗量过多、地质条件不利露天节理、矿层不稳固和空穴、延时定时和序列不当、延时不精确、发生反向爆破、以及台阶上部岩石松散等	The major causes of flyrock are inadequate burden, inadequate stemming length, drilling inaccuracy, excessive powder factor,unfavorable geological conditions open joints, weak seams and cavities, inappropriate delay timing and sequence, inaccuracy of delays, back break and loose rock on top of the bench
飞石是由过多的气体能产生的	Flyrock is produced by excess gas energy
