覆盖层的抛掷爆破是用爆炸力量将爆破岩石定向抛到预定废石堆而不需再行整理废石堆的新技术,其优点是可节省重整理和搬运废石的时间与费用,抛掷之后即可马上开始下一循环的作业。任何开采作业中抛掷爆破的成功取决于若干相互作用的因素,如凿岩爆破方案、爆破岩层的外形、废石堆位置、空气阻力及经 Blasting blasting of overburden is a new technique that uses blast force to target blasting rock to a predetermined waste rock pile without the need to re-arrange the waste rock pile. The advantage of this method is that it saves the time and expense of re-arranging and transporting the rock waste, You can start the next cycle of operations immediately. The success of throwing a blast in any mining operation depends on several interacting factors such as the rock blasting scheme, the shape of the blasting rock formation, the location of the waste rock pile, the air resistance,
