摘要
在露天台阶爆破过程中,在台阶前预留一定厚度渣堆的压渣爆破得到广泛的运用。分析了炮孔爆破的破岩机理,在此基础上阐述了压渣爆破的破岩机理。通过合理确定渣堆厚度以及爆破参数,将压渣爆破运用于建龙矿业马剑子沟采区,爆破后取得了良好的爆破效果。
In the process of open-pit bench blasting, the extrusion blasting of rock slag pile before the benches is widely used. The article analyzes the rock breaking mechanism of the blasting hole, expounds the rock breaking mechanism of the extrusion blasting.Through reasonably determining the thickness of rock slag pile and blasting parameters, the company applies the extrusion blasting to Majianzigou mining area, which achieves good blasting effect.
