控制爆破技术在露天矿山高陡边坡的应用OA

To prevent the hazards posed by flying and rolling rocks generated during blasting operations on high and steep slopes in open-pit mines to surrounding buildings,and to improve the efficiency of slope treatment in the Oushan open-pit limestone mine,this article proposes a technical method combining control blasting with conventional blasting.By optimizing the decoupling charge structure,the blasting area is divided into three zones,and the blasting network parameters are determined based on engineering experience.Field blasting tests are conducted.The results show that this control blasting technology effectively eliminates secondary disaster such as flying and rolling rocks during the treatment of high and steep slopes.While ensuring construction safety,it also resolves the contradiction between mining progress and safety protection.
