磁化水在煤层注水中的应用

为了防止煤与瓦斯突出、冲击矿压等灾害，预防自然发火等，探讨了磁化水的性质、磁场作用机理及磁技术在煤层注水方面的应用前景。研究结果表明，必须在合适的磁场作用下水的表面张力才能降低到最小；磁处理后，可以明显减少水中某些元素，这对于减少矿井水对管道的腐蚀具有重要意义：磁化水能够增加煤岩体的饱和吸水量，增加水在煤岩介质中的渗透性。磁场作用机理主要表现在可以使水分子缔合体分解成为单分子水或较小的缔合水分子，使水分子键长、键角加大，使水的活性增加、黏性降低。磁化水在煤层注水方面具有良好的应用前景。

Application of magnetized water in coal seam water infusion

To preventing coal and gas outburst,rockburst and spontaneous combustion.In this paper characteristics of magnetized water,action mechanism of magnetic field and application foreground are discussed.The researches drew the following conclusions: surface tension of water can reduce to the minimum in the appropriate intensity of magnetic field;some elements of water can be lessened clearly after water is magnetized;magnetized water can increase saturated infusion quantity and permeation of coal or rock.The action mechanism of magnetic field is mainly as follows: it can break the large associated water molecules down into single molecules and small associated molecules,increase bond length and bond angle,enhance water activity and decrease viscidity of water.The studies also show that magnetized water has a good application prospect in coal seam infusion.
