摘要
新田煤矿为基建矿井,采用斜井开拓,井筒施工进入至玉龙山灰岩含水层时,发生了出水,造成了三条井筒局部被淹。井筒出水之后,采取了在井筒超前预注浆封堵、加固含水层的方法,安全顺利地通过了该含水层。
Xintian Colliery is a capital construction mine opened up by inclined shaft,in which water bursting occurred in shaft constructing into Yulongshan limestone aquifer,resulting in partial flood in 3 shafts.Methods such as leading pregrouting plugging in shaft and reinforcing aquifer were adopted after water bursting in shaft,which enabled construction to pass the aquifer safely and smoothly.
