岩石松动爆破炮孔密集系数研究

摘要

As the technology of small burden and large spacing loose blasting is used, the area of spacing pattern can be increased, the consumption of hole and explosive can be decreased, the fragmental effect of rock can be improved.The results of theoretical analysis and engineering practice show that more reasonable coefficient of hole spacing is m=1.5～2.5.%宽孔距岩石松动爆破技术具有增加孔网参数、降低炮孔和炸药消耗、改善破碎效果等优点。理论分析、试验研究和工程实践结果表明：岩石松动爆破较为合理的炮孔密集系数取值为1.5～2.0。
