摘　　要：为保障安家岭露天矿东帮到界过程中的生产安全,对比微差控制爆破和二氧化碳静力爆破2种技术优缺点,在计算炸药爆破时振动距离和飞石安全距离基础上,提出到界边坡区域的爆破控制方案,确定2种爆破方案的应用范围及爆破参数。结果表明:东帮开采地表界以西50 m范围内应采用二氧化碳静力爆破;东帮开采地表界以西50~80 m应采用外包作业微差控制爆破,自营应采取微差控制爆破。order to ensure the production safety in the process of reaching the boundary of east slope in Anjialing Open-pit Mine,the article compares the advantages and disadvantages of millisecond controlled blasting and carbon dioxide static blasting.Based on the calculation of vibration distance and flying stone safety distance during explosive blasting,the article proposes blasting control scheme to the boundary slope area,and determines the application scope and blasting parameters of two blasting schemes.The results show that we adopt carbon dioxide static blasting within 50 m to the west of the east slope mining surface boundary,adopt outsourcing millisecond controlled blasting within 50 m to 80 m to the west of the east slope mining surface boundary,and adopt millisecond controlled blasting for self support.

关 键 词：二氧化碳静力爆破 微差控制爆破 爆破参数 到界边坡 安全距离
