罗克休与马丽散在斜井过含水流沙层冒顶处理中的应用

黄陵矿业有限公司一号煤矿四号风井瓦斯斜井井筒在掘进至含水流沙层时发生冒顶事故,无法正常掘进,采用马丽散N型密闭空气、阻隔导水通道、粘结松散围岩,罗克休泡沫充填冒落区的方法,达到加固顶板、充填空洞的目的,显著提高了四号风井瓦斯斜井含水流沙层段围岩稳定性,且加快了瓦斯斜井过含水流沙层的速度,创造了良好的效益。

Application of Roesil Foam and Marithan in the Puking Treatment when Inclined Well Crossing Water-bearing Quicksand Layer

The No.4 air shaft gas inclined shaft of Huangling Mining （Group） Co., Ltd. No.1 Coal Mine met puking in advancing into water bearing quicksand layer, and failed to advance normally. Marithan N type sealed air, blocking water channel, cementing loosesurrounding rock, rocsil foam filling method are used to strengthen the roof and filling the empty, ,which significantly improved the surrounding rock stability of No.4 wind wells gas inclined water-bearing quicksand layer, and accelerated the pace of gas slope throughaqueous quicksand layer, creating a good benefit.
