中文摘要：

从突水水源和导水通道两方面分析了留庄煤矿12102工作面特大突水灾害的成因,结果表明：12102工作面直接充水水源为第三层灰岩含水层静储量水,补给水源是侏罗系红层水。导水通道为断层活化引起的冒裂带沿断层向上发育。断层活化作用与工作面内断层走向和工作面推进方向有关,12102工作面推进方向与断层走向近于垂直,与断层倾向相反,当顶板上方有含水层时容易发生断层活化充水。

英文摘要：

Causes of severe water inrush on Face 12102in Liuzhuang Mine are analyzed,which relate to the source and passage of the inrush.The analysis indicates that the static water in the third limestone aquifer of the Carboniferous system is the direct source of water in Face 12102,with additional water from the Jurassic red strata.Fault activation provides water passa-ges,where the fractured zone develops upwards along the fault.Fault activation is related to the strike of the fault in the face and the direction of face advance.The direction of Face 12102ad-vance is approximately perpendicular to the fault strike and opposite to the fault dip.When an aq-uifer exists above the roof,the fault is apt to being filled with water as a result of activation.
