摘要
矿床充水是指煤矿床开采过程中,各种来源的水通过不同的方式和途径进入矿坑的过程,其特征由充水水源、充水方式和通道以及影响充水性质和强度的其它因素所决定。本区处于干旱沙漠地带,地面水稀少,地下水补给来源贫乏,仅为大气降水,井田构造以单斜构造为主,断裂发育较少,因而导致本区岩层含水性差。根据井田水文地质条件,结合邻近生产矿井的水文地质条件特征和充水因素进行分析评述。
Full water of mineral deposit refers to all kinds of origin water came to pit through different ways during the coal mine exploitation,which characters were depended by source of water,mode,channels and other factors to effect full water quality and intensity.The coal mine located in arid desert,few water on face ground,indigence origin supplement for the groundwater,only atmospheric water,monoclinal structure as the main conformation,seldom crack growth,to form the bad ability to contain water.According to hydrogeology condition,combined with the hydrogeology condition character of the near mine,the full water factors were analysed in this article.
