摘要
为了研究不耦合装药结构与不同介质耦合装药结构的定向断裂光面爆破效果,得到最佳装药结构,从而解决工程爆破中存在的技术问题.以华泰煤矿为工程背景,采用4种装药结构,分别通过实验室实验和现场工业实验对水-空气耦合、水耦合、空气耦合和水不耦合进行巷道围岩的爆破效果进行分析对比,实验结果证明,在华泰煤矿采用水耦合爆破,可使围岩或预留岩面的完整性、稳定性较好.
In order to study the effect of smooth blasting directional fracture under decoupled and coupling of different media charge structure,get the best charge structure and then solve the technical problems existing in the engineering blasting,four kinds of charge structure were used water -air coupling,water coupling,air coupling and water decoupled）as the engineering background of Huatai coal mine in the laboratory and in the field,the blasting effect was analyzed and contrasted,the experimental results show that it make the surrounding rock or reserved rock face have a good completeness and stability to in Huatai coal mine with water coupling blasting.
