摘要
煤层注水预湿是采煤工作面防尘的治本措施，添加湿润剂是改善煤层注水效果的重要途径。本文对煤层注水添加湿润剂的作用、效果、最佳浓度、对浮选的影响及湿润剂选择等问题进行了探讨，得出了相应的结论。
Prewetting of coal seams by water infusion is an essential measure for dust control at working faces.Adding of wetting agent is an important approach for improving water infusion.This paper discusses the function,effect,optimal concentration,its effect on floatation and selection of wetting agent for coal seam infusion.Some conclusions are obtained.
