摘要
陕西彬长矿区亭南煤矿207工作面为二盘区第五个回采工作面,采用综采放顶煤回采工艺。回采前工作面采用采前预疏放、回采过程中采用向相邻采空区打煤泥水,低位泄水和面后排清水以及仰采范围内采用阶梯式放水等综合措施,彻底解决工作面回采期间的水害问题。通过对亭南煤矿207工作面综合防治水技术应用研究,积累了复杂条件下工作面防治水技术经验。
Working face 207 in Tingnan coal mine 2 is the fifth working face in the second panel,adopts fully mechanized caving technology.Comprehensive measures such as pre-dredging before mining,pumping slime water to adjacent goaf in the process of stoping,low drainage and clear water at the back of the face,and ladder-type water discharging in the range of upward mining are adopted on the working face to completely solve the prevention and control of water damage during stoping.
