露天松动爆破技术在河西金矿的试验与应用

The Explosion Trial in Open-Air Gold Mine of Hexi Gold

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,确定出合理的孔距、排距、最小抵抗线等爆破参数及爆破方式,从根本上控制了飞石,缓冲了爆破地震波,从而降你了采矿成本,对今后露天生产工作有很好的指导意义,其经济效益及社会效益显著。

because the open-air gold mine of the Hexi near the village,road, and high wire , so we take the trial in it , by trying , we draw the responsible conclusion to parameter o explosion , and draw the responsible conclusion to how. Thereby ,we low the shock of explosion, and low the cost of the explosion, the meleage is very obvious in economy and social.
