工业爆破的特点是频率高、持续时间短、随爆心距和时间衰减快、爆破地震的震源较浅。露天矿爆破就是应用炸药爆破时化学能的释放,在药包的周围产生高温和高压,使附近岩石压碎、破裂。对于矿山生产来说,希望炸药爆炸时,产生的能量大,威力高、爆下的矿岩越多越好。但是,在离开爆源一定距离后,一部分能量以弹性波的形式传播,其震动强度超过一定程度时会引起工程结构的损坏,给生产爆破带来不利的一面。对于露天矿边坡来讲,特别是固定边
Industrial blasting is characterized by high frequency, short duration, fast decay with the burst center distance and time, shallow source of blasting earthquakes. Opencast blasting is the release of chemical energy in the application of explosives blasting, resulting in high temperature and pressure around the kits, crushing and rupturing nearby rocks. For mine production, it is hoped that when the explosives explode, the energy generated is high and the power is high. The more rock ore blasting off, the better. However, after leaving a certain distance from the explosive source, a part of the energy spreads in the form of elastic waves. When the vibration intensity exceeds a certain level, the engineering structure will be damaged, which brings unfavorable side to the production blasting. For open pit slopes, especially fixed edges
