【摘要】：通过新桥煤矿2501综采工作面煤层注水试验,研究了注水压力和湿润剂浓度对2501综采工作面湿润半径的影响规律。结论表明,通过煤层注水后可以有效提高工作面煤体中的含水率,随着注水压力和湿润剂浓度的增高,工作面煤层注水的湿润半径也增大;当注水压力为6 MPa、湿润剂浓度为7‰时,湿润半径达3.2 m。
[Abstract]:The influence of water injection pressure and wetting agent concentration on the wetting radius of 2501 fully mechanized coal face in Xinqiao Coal Mine is studied. The water cut in coal body can be increased effectively by injecting water into coal seam. With the increase of water injection pressure and wetting agent concentration, the wetting radius of coal seam water injection can also be increased, when the water injection pressure is 6 MPA and the wetting agent concentration is 7 鈥，
