综放工作面综合防治水技术研究与应用

Research and Application of Comprehensive Water Control Technology in Fully Mechanized Caving Face

综采放顶煤开采技术作为一种高产高效采煤技术,因开采煤层厚度大、开采面积大、放顶工艺等因素,与其他开采工艺相比,其采动影响范围大幅增大,采场围岩导水裂隙带发育高度增加,工作面涌水、突水概率也相应增大,加大了水害治理的难度。为有效控制综放工作面水害的发生,从综放工作面涌水机理、出水特征与规律、水害预防与治理影响因素着手,采用多种治水技术,提高水害治理效果,确保矿井的安全高效生产。

To effectively control the occurrence of water hazards in the fully mechanized caving face,the author starts with the mechanism of water inflow,the characteristics and laws of water outflow,and the influencing factors of water hazard prevention and control,proposes multiple water control technologies to improve the effectiveness of water hazard control,which ensures the safe and efficient production of the mine.
