| 摘 要： | 煤层注水是治理煤矿井下灾害的一种有效方法,但由于煤自身的构成组分、变质程度、裂隙发育等因素的不同,导致注水后其润湿效果差异较大。解决这一问题,可通过在水中添加表面活性剂的方法来实现。结合余吾煤业屯留煤矿3#煤层的实际情况,选择合适的活性剂,经过现场试验取得了较好的成果。

| Abstract: | At present coal seam water infusion is an effective method to control the mine disasters.But,the different factors such as the composition of coal itself,crack growth lead to the wetting effect is quite different.After water infusjon,by adding surfactants in water can solve this problem.Combining the actual situation in 3# coal seam of Tunliu Coal Mine,Yuwu Coal Industury Co ltd choose a suitable active agent.The field tests have achieved good results. |
