摘 要:四川省攀枝花市宝鼎矿区的煤层厚度、倾角变化较大,地质条件极复杂,经常遇到背斜、断层、变薄带、冲刷带等情形,开采难度极大。为此,花山煤矿6244工作面在回采巷道掘进过程中揭露部分断层,采取钻探、巷道揭露等方式对工作面断层地质变化情况进行分析判断,决定通过重新掘进工作面降低风道、工作面原址缩机减架等方式以完成改造工作面的方案,实现工作面快速通过走向断层群。经实践,6244大倾角综采工作面过走向断层群技术具有很好的推广应用价值。The coal seam thickness and dip angle of Baoding mine in Panzhihua City,Sichuan Prov⁃ince vary greatly,and the geological conditions are extremely complex,often bumping into back slope,fault,thinning zone,scouring zone and other situations,making mining extremely difficult.For this rea⁃son,the 6244 working face of Huashan coal mine reveals part of the fault in the process of back mining tun⁃neling,using drilling and tunneling to expose the geological changes of the fault in the working face to ana⁃lyze and judge,and decide to complete the program of transforming the working face by re-digging the working face to lower the air duct,and shrinking the machine and reducing the frame at the original site of the working face to realize the working face quickly crossing towards the fault group.After practice,the technology of 6244 large inclination comprehensive mining working face crossing the fault group has good promotion and application value.
