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。
After the Xinqiao mine coal 2501 fully mechanized coal face of coal seam water injection test,studays the influence of the injection pressure and the concentration of wetting agent on 2501 fully mechanized face wetting radius. The conclusion shows that the coal seam water injection can effectively improve the coal water body rate, with the increase of injection pressure and concentration of wetting agent, wetting radius of working face coal seam is bigger; when the injection pressure is 6 MPa,concentration of wetting agent was 7 per thousand, wetting radius is 3.2 m, the best wetting effect.
