露天矿硬岩开采中凿岩爆破法占主导地位,然而,爆破时由于产生震动、噪音及飞石对环境带来危害。通过采取炮孔中分散装药、选择合理起爆间隔时间、孔底起爆、降低台阶高度、减小炮孔直径,不超钻炮孔及采用隔离爆破等措施可减轻环境危害,但这些措施相互影响,且往往增加开采费用。因此,随着高效率挖掘设备的发展,人民愈来 Opencast mining is dominated by the rock-blasting method in hard rock mining. However, noise and fly-rock are harmful to the environment due to vibration and vibration during blasting. These measures can reduce the environmental damage by adopting the method of dispersing the charge in the blasthole, choosing reasonable detonation interval time, detonating the bottom of the blasthole, reducing the height of the blasthole, reducing the diameter of the blasthole, not super-drilling the blasthole and adopting the method of isolation blasting , And often increase mining costs. Therefore, with the development of high-efficiency mining equipment, the people are getting more and more people
