摘要
胜利东二号露天煤矿地质资料复杂,硬岩分布不均对生产造成极大影响,本文通过节理裂隙、炸药、雷管、孔网参数、台阶装药技术对爆破效果的分析,对该矿硬岩的处理提出建议。
Opencut coal mine No.2,east of Shengli is geologically complicated,the unexen distribution of the hard rock is of great adverse effect on coal production.The text is trying to make some suggesttions on the treatment of the hard rock through the analysis of joint fissure,dynamite,detonator,parameters of hole distribution,terrace installation of dynamite and their explosive effects.
