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。
The effect of water injection pressure and concentration of wetting agent on the wet radius of 2501 fully mechanized coal mining face was studied through coal seam water injection test at 2501 fully mechanized coal mining face in Xinqiao Coal Mine. The conclusion shows that the water content in coal face can be effectively improved by injecting water into coal seam. With the increase of injection pressure and concentration of wetting agent, the wetting radius of water injection in working face coal seam also increases. When the water injection pressure is 6 MPa, The concentration of 7 ‰, the wet radius of 3.2 m.
