前言我矿营盘山采区在露天采场中,高出其他采区近200米,虽然有其独自的开拓运输系统,但爆破对山下采场有直接影响。因此,在考虑爆破方案时,根据生产要求,一不堵塞山下采场排洪系统工程的泄水井,二在爆破后,不再进行溜井上口或台阶间联络道的穿孔爆破。要求一次放炮,避免多次放炮影响生产时间。因而在地形条件复杂、爆区200多个炮孔,40多吨炸药、爆破岩量达37万吨的情况下,我们采取的措施有:①后
Preface I mine camp Panshan mining area in the open pit, higher than other mining areas nearly 200 meters, although its own open up transportation system, but the blasting on the mountain stope have a direct impact. Therefore, when considering the blasting plan, according to the production requirements, one will not block the drainage wells of the underground stope drainage system project, and after the blasting, the piercing blasting at the catchy upper level or between the steps will not be carried out. Requires a blast, to avoid multiple blasting affect production time. Therefore, in the complex terrain conditions, the blast area of more than 200 blast holes, more than 40 tons of explosives, rock burst volume of 370,000 tons of cases, we take measures: ① after
