【摘要】 立足于解决梅山铁矿实际存在的生产技术问题,将孔底起爆落矿新工艺较成功地应用于不同炸药种类、不同分段高度、不同炮孔直径、不同爆破类型等,均取得了显著的爆破效果,并开展了爆破孔网参数优化试验研究。这一新工艺的成功实践,无疑将对国内地下矿山更大范围推广产生深远的影响。更多还原

【Abstract】 This paper is based on solving the practically existing technical problems during the production process in Meishan iron mining. Remarkable blasting effects has been reached by successfully using the new technique of mine-fall with ignition beneath holes to different types of explosives, different heights of segments, different diameters of blasting holes, different bypes of blasting, and so on. Testing study on optimizing parameters of blasting holes network is also carried out. It is no doubt that the successful practice of this new technique will bring far-reaching influence on generalization of domestic underground mining.更多还原
