随着生产的发展,矿石产量不断增加,开采速度大幅度提高,爆破规模越来越大。我国露天矿山一次爆破炸药量高达几千吨,甚至到万吨以上。炸药量的增加,爆破次数频繁,爆破所产生的地震波对建筑物和构筑物的破坏作用,越来越显得重要和突出。爆震的破坏作用阻碍了生产的发展,日益引起人们的重视。有的矿山正常生产爆炸工作威胁着周围民房的安全,甚至引起民房的损坏;有的矿山爆破作业使工业厂房产生裂缝,或变电站高压开关跳闸;有的矿山爆破作业促使边坡滑动,不得不修改边坡角,增大边坡处理量,降低采矿经济
With the development of production, the output of ore is continuously increasing, the rate of exploitation is greatly increased, and the scale of blasting is getting larger and larger. China’s open-pit mines blast explosives up to several thousand tons, even to more than 10,000 tons. Increasing the amount of explosives, frequent blasting, seismic waves generated by blasting the destruction of buildings and structures, more and more important and prominent. The damaging effect of detonation hinders the development of production and draws more and more attention. Some mines normal production of explosions threaten the safety of surrounding houses, and even caused the destruction of houses; some mine blasting operations to produce cracks in industrial plants, or substations high-voltage switch tripping; some mine blasting operation to promote the slope slide, had to modify Slope angle, increase the amount of slope processing, reduce mining economy
