爆破是采矿生产的主要工序之一。爆堆的松散、堆积情况,特别是爆破岩块的组成直接影响着装载、运输和爆碎等后续工序的效率和采矿生产的总成本。而爆破块度组成又是由岩石物理力学性质、岩层构造、炸药和爆破参数等所决定的。在已定的矿岩性质条件下,寻求最合理(即最优)的炸药和爆破参数,以获得使采矿生产总成本最低的“最佳”块度组成一直是各国采矿科技工作者所致力研究的课题。多年来,在寻求爆破块度组成与炸药和爆破参数之间关 Blasting is one of the major processes in mining production. The loose, buildup of blasts, and in particular the composition of the blasting rock mass, have a direct impact on the efficiency of subsequent processes such as loading, shipping and blasting, and the overall costs of mining production. The composition of the blasting block is determined by the physical and mechanical properties of rock, rock structure, explosives and blasting parameters. Finding the most plausible (ie, optimal) explosives and blasting parameters to achieve the “best” lofty composition that minimizes the total cost of mining production has been the subject of research efforts by mining scientists across established countries The subject. Over the years, the search for the relationship between the block composition of explosives and explosives and blasting parameters
