摘 要:随着开采年限的不断增加,永平铜矿采区已进入了深凹陷露天开采,局部形成了高陡边坡,临近边坡爆破对边坡的安全稳定问题日益凸显,为了解决这一问题,通过分析边坡控制爆破原理和根据矿山现有钻孔设备,结合现场爆破实践,确定了大孔径垂直深孔在边坡控制爆破时的爆破参数,论证了大孔径垂直深孔在控制爆破中的可行性。Yongping copper mine has entered into deep open-pit mining phase after these years mining. High and steep slope has been formed. The influence of blasting near slope on the safety and stability of high and steep slope is increasingly obvious. Through analyzing the slope explosion principle, the blasting parameters of large diameter vertical hole was confirmed and the feasibility of large diameter vertical hole in slope controlled blasting was demonstrated On the basis of present drilling facilities and blasting practice.
