煤矿综采工作面防治水技术研究

煤矿综采工作面的顶层透水是困扰煤矿的直接水灾害。随着开采方法的现代化和开采的增加，综采工作面的顶层透水对煤矿的威胁也在增加，对煤层顶板岩体的破坏越来越大。以某大型矿井为研究对象，论述综采工作面顶板防治水勘探的主要内容和方法，论证了遥感水文地质调查、物探、水文化学、环境同位素等先进方法在煤矿水文地质勘探和水灾害处理“三位数预测方法”中的应用。同时，用 FLAC^3D软件对综采工作面的结构进行了数值模拟分析，结果表明低角度断层和采矿引起的裂缝为工作面突水提供了通道。研究成果为综采工作面防治水研究提供了依据。

Study on water control technology in fully-mechanized working face

The permeation of the top layer of the fully-mechanized coal mining face is a direct water disaster that plagues the coal mine.With the modernization of mining methods and the increase of mining，the threat of permeable top layer of fully-mechanized mining face to the coal mine is also increasing，and the damage to the roof rock mass of the coal seam is increasing.Taking a large mine as the research object，discussing the main content and methods of water exploration for the roof of a fully-mechanized mining face，it also demonstrated the application of advanced methods such as remote sensing hydrogeological survey，geophysical prospecting，hydroculture，environmental isotope in coal mine hydrogeological exploration and water disaster treatment "three-digit prediction method".At the same time，FLAC^3D software was used to carry out a numerical simulation analysis on the structure of a fully-mechanized mining face.The results showed that low-angle faults and cracks caused by mining provide a channel for water inrush from the face.The research results provided a basis for the research on water prevention and control in fully-mechanized mining face.
