“三软”煤层长钻孔注水防尘技术试验研究

Study on Technology for Water Injection by Long Bore Hole in Three Soft Seam

以郑州矿区典型的“三软”煤层综放工作面为对象，试验研究了长钻孔注水防尘技术，取得了“三软”煤层长钻孔注水经验和参数，为郑州矿区类似条件的工作面推广该方法提供了参考。

In this paper, technology for water injection by long bore hole in fully mechanized mining face wasstudied, relevan experience and some parameter were acquired, which provide a reference for using this method insimilar faces.
