摘 要:针对巷道顶板隔水层缺失或采掘扰动作用下导通上覆含水层贯通巷道突水问题,采用现场水文地质调研、理论分析、数值计算,并基于"三图-双预测法"对巷道突水机理进行研究。结果表明:矿区导水带发育裂隙未贯通含水层,巷道顶板冒裂安全区域划分为冒裂危险强、中、弱及安全四大区,当工作面开采至600 m处时,顶板产生塑性破坏(冒裂带)高度达174 m,裂采比13.5∶1。In order to solve the problem of water inrush through roadway under the action of lack of water-proof layer of roadway roof or mining disturbance,the field hydrogeological survey,theoretical analysis and numerical calculation were adopted,and the mechanism of water inrush through roadway was studied based on the"three-graph and double-prediction method".The results show that the development of fissures in the water guide zone of the mining area does not penetrate the aquifer,and the safe area for roof burst is divided into four areas with strong,medium,weak and safe risks of roof burst.When the working face is mined to 600 m,the height of roof plastic failure(roof burst zone)is174 m,and the ratio of roof burst to mining is 13.5∶1.
