孔底起爆技术在胡家峪铜矿的工业试验研究
TESTS ON HOLE-BOTTOM PRIMING IN HUJIAYU COPPER MINE
【摘要】 对孔底起爆和孔口起爆的作用机理作了对比分析 ,并对孔底起爆技术进行了现场爆破试验。试验结果表明 :实施孔底起爆 ,爆破效果良好 ,降低了二次破碎成本 ,具有推广价值。
【Abstract】 The difference between action mechanism of hole-bottom priming and hole-mouth priming was stated.The field tests for hole-bottom priming were done.The results show that the blasting effect is excellent and the cost of secondary blasting is greatly reduced when using hole-bottom priming.
