摘　　要：新驿煤矿副立井2003年建成,该井在建井过程中进行预注水泥浆封水堵漏井筒涌水,成井后也进行水泥、水玻璃浆液井壁注浆防止渗水和漏水。时至2009年6月,井筒出水量达8m3/h左右,于是采用改性脲醛树脂化学浆材再次进行破壁注浆,将整个井筒涌水量降至0.5m3/h以下,取得了满意的注浆效果。The vice well of XinYi coal mine was established in 2003,which had been grouted with cement paste before established in order to prevent leakage of water form the coal well.Established,water-glass also had been used,but result was not bad.When to June,2009,the total floating water add up to 8m^3/h.Then taking the injection of urea-formaldehyde has made the satisfactory progress,with the amount of mine inflow declined to the 0.5m^3/h below.
