【摘要】：通過(guò)新橋煤礦2501綜采工作面煤層注水試驗(yàn),研究了注水壓力和濕潤(rùn)劑濃度對(duì)2501綜采工作面濕潤(rùn)半徑的影響規(guī)律。結(jié)論表明,通過(guò)煤層注水后可以有效提高工作面煤體中的含水率,隨著注水壓力和濕潤(rùn)劑濃度的增高,工作面煤層注水的濕潤(rùn)半徑也增大;當(dāng)注水壓力為6 MPa、濕潤(rùn)劑濃度為7‰時(shí),濕潤(rùn)半徑達(dá)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，
