白云石矿小台阶爆破参数的研究

Research on Small Bench Blasting Parameters in Dolomite Mine

爆破漏斗试验作为合理选择爆破参数、优选炸药品种、提高爆破效率等的基础,在爆破技术的发展中起了重要作用,本次试验表明,合理的爆破参数,可以使爆下矿石粒度分布较均匀,无突变现象,爆堆集中,达到安全生产需要目的,中孔小台阶爆破,穿孔机动灵活,爆破工艺简单,易于控制,适合小型露天非金属矿使用。

Blasting funnel test as a reasonable selection of blasting parameters, optimization of explosives, foundation to improve the blasting efficiency, has played an important role in the development of blasting technology, the test, the reasona- ble blasting parameters, can make the explosives ore size distribution is uniform, no sudden phenomenon, concentrate the blasting pile, to achieve safe production . In the small hole bench blasting, Perforation is flexible, blasting process is sim- ple, easy to control, suitable for small open non-metallic mineral use.
