摘要
针对河西金矿露天采矿场紧靠居民区、公路和高压线的复杂地理环境,通过一系列爆破试验,确定出合理的爆破参数及爆破方式,控制了飞石,缓冲了爆破冲击波,降低了采矿成本,经济效益及社会效益显著。
Because the open-pit of Hexi Gold Mine is near the village ,road, and high wire ,the environment is very complicated. By a series trials, the responsible conclusion of blasting parameters and blasting mode were determined. Thereby, the flying rock and the shock wave of explosion were controlled, and the explosion cost reduced. Economic and social benefits is very obvious.
