永平铜矿露天边坡的控制爆破技术

Controlled Blasting Techniques for Opencast Slope in Yongping Copper Mine

永平铜矿边坡爆破量大，由于受穿孔设备的限制，对边坡预裂爆破后，往往会留下未爆下的三角块，用人工清理这部分三角块费用高、效率低。近年来，在实践中采用了钻凿浅孔和减震孔的爆破法，取得了良好的效果。

here was a large amount of slope blasting in Yongping Copper Mine.Owing to the limitation of drilling equipment,after the slope was pre-splitting blasted,some unblasted triangle blocks were usually left on the slope,which had to be manually cleaned out,so as leading to high cost and low efficiency.In recent years,the blasting methods with shallow holes and damping holes was used in the practice and obtained good results.
