中文摘要	通过对干旱区露天煤矿非构造裂隙岩性特性、岩体破裂面、裂隙产状以及爆破过程中出现问题的分析,探讨了非构造裂隙岩体对爆破作用的影响。在此基础上,对起爆位置、装药结构、起爆顺序等关键爆破作业环节进行了分析,对爆破设计方案进行了优化,并对爆破效果进行了评价。结果表明,对于干旱区非构造裂隙岩体发育、爆破后会产生较大的岩石大块的矿区,根据岩体倾斜状况,推荐采用对称或不对称的"V"型逐孔毫秒微差起爆网路;对于受剪节理和张节理共同作用非构造裂隙岩体,推荐采用分区、分段多排孔排间毫秒微差起爆网路,不耦合柱状装药深孔爆破。
英文摘要	By analyzing the non-structural fractured lithologic characteristics, plane of fracture of rock mass, attitude of fracture and blasting process in a typical open pit coal mine, effects of non-structural jointed rock mass on the blasting are disscussed. Based on such results, the key blasting operations, such as detonating position, charge structure, initiation pattern etc. are analyzed. Then, the blasting design is optimized and blasting effect is evaluated. Results show that the large rock bulk could be generated after blasting for the mining area in the arid area with non-structural fractured rock mass development. The symmetric or asymmetric V-shaped oblique line of hole-by-hole millisecond explosion initiation network is recommended according to the inclination of the rock mass. As for the non-structural fractured rock mass affected by shear joints and tension joints, the adoption of zoning and subsection-based interline explosion millisecond initiation network among multiple lines as well as deep-hole blasting with non-coupling column charge is suggested to use.
