露天煤矿采场的掏槽爆破是较为复杂的控制爆破技术。针对黑岱沟露天煤矿转向时延深工程遇到的爆破规模大、施工复杂、施工工期相对紧张等问题,研究结合采矿要求和爆破条件选定了斜坡道半断面和平段整体一次成型掏槽爆破方案,对起爆网路、爆破参数以及工程管理组织进行了设计与优化,解决了上述难题,加快了转向扩帮进度,为类似条件下的工程项目提供了参考与借鉴。 Open pit blasthole blasting is a more complex control of blasting technology. Aiming at the problems such as large scale of blasting, complex construction and relatively tight construction period encountered in steering transformation of open seam mine in Heidaigou, this paper studies the combination of mining requirements and blasting conditions, Program, the initiation network, blasting parameters and project management organization has been designed and optimized to solve the above problems, speed up the progress of expansion to provide similar projects for reference and reference.
