摘要
带压开采矿井导水断层突水是矿井采掘中最常见的突水灾害事故之一,一般都会造成较大的危害,经常造成掘进头或工作面停产,甚者可导致矿井被淹。通过注浆封堵技术,对充水通道进行加固与封堵,截断其补给水源,可以有效解放带压区因充水通道而不能开采的煤炭资源,提高矿井回采率。
In mine with pressure mining, water inrush by water guide fault is one of the most common accidents in mine, which usually causes great harm,often causes the working face to stop production,and can he flooded to the mine. Through grouting sealing technology, the water filling channel can he strengthened and plugged,which can effectively liberate the coal resources in the pressure zone and improve the recovery rate of the mine.
