摘要
对煤层注水的水分蒸发现象进行了研究 ;提出了注入水分蒸发的力学平衡公式 ;研究了影响水分蒸发的各项因素。在此基础上 ,提出了在注水钻孔中添加粘尘棒 ,阻止注入水分过早蒸发的新方法 ,并进行了纯水和粘尘棒溶液在煤体中蒸发的试验。
The phenomenon of water vaporization during infusing water into coal seam was studied. The dynamic equilibrium formula of the vaporization of infusing water was presented. The factors affecting the water vaporization were investigated. A new method by adding a dust adhering bar to the drilling hole for water infusion to prevent too rapid vaporization of the infused water was presented. The vaporization processes of pure water and solution of dust adhering bar in coal body were tested and compared.
