摘要
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。
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.
