摘　　要：为了提高煤层注水的效果,采用理论分析的方法,研究了磁化水的理化特性和进行煤层注水时的增注机制.结果表明,磁化水的水分子链(团)中的氢键会发生弯曲和局部断裂,水分子间的引力常数变小,水分子得到活化,导致水的表面张力降低,加大了煤体对水分子的吸附能力,提高了煤体的润湿效果;水的粘度系数的降低,加快了水在煤体中的渗流速度,提高了水在煤体中的渗透率.分析表明,磁化水在煤层注水方面的应用具有良好的应用前景。Physicochemical properties of magnetized water are analyzed and the mechanism of coal seam injection of magnetized water is studied by theoretical analysis in order to increase effect of coal seam water injection in this paper. The results show that the hydrogen bond of molecular chain （group） of magnetized water bends or locally breaks. The gravitation constant among water molecules becomes smaller and water molecules are activated, which lowers water surface tension, enhances coal＇s ability to absorb water molecule and improves the wetting effect of coal body. The seepage velocity of water in coal body is speeded up and the seepage rate of water is improved due to the decrease of the viscosity coefficient of water. It is shown by this analysis that the application of magnetized water in coal seam injection is of good prospect.
