摘要
依据爆炸力学、弹性力学及岩石力学的一般理论及成果 ,结合金堆城露天矿大孔距预裂爆破的实践 ,建立了相应的力学模型 ,并根据该模型认真分析和确定了露天矿大孔径预裂爆破工艺中孔网参数、不偶合系数、装药及起爆方式的合理性。同时为了适应矿山机械化装药的要求 ,建议进行车制乳化炸药预裂爆破的技术研究。
According to the general theory and achievements of explosion mechanics,elasticity mechanics and rock mechanics,corresponding mechanics model was established by combining the practice of large pore size presplit blasting in Jinduicheng open pit mine.And the resonableness of the technology of large pore size presplit blasting was analysed and determined.Besides,in order to meet the need of mechanized regent feeding in mines,the technical research on presplit blasting of emulsified explosives was suggested.
