为了竞争和生存,采矿作业必须保持高水平的开采效率。为此目的,已经对钻孔和爆破工序给予了很大注意;改善这一工序,既可以节省直接成本,也可以通过改善破碎块度来降低后续工序的成本。在炸药产品中添加铝粉可在降低钻孔和爆破成本方面起重 In order to compete and survive, mining operations must maintain a high level of productivity. To this end, much attention has been given to drilling and blasting processes; improving this process can either reduce direct costs or reduce the cost of subsequent processes by improving the degree of fragmentation. The addition of aluminum powder to explosives products can help reduce drilling and blasting costs
