| 摘 要： | 刘桥二矿在开采4煤过程中，七含突水次数达38次之多，严重影响煤矿安全生产。文章在系统地分析刘桥二矿七含涌突水概况的基础上，提出了该矿七含涌突水的主要机理为断裂构造的控制作用和矿山压力的促进作用；指出了砂岩含水层的裂隙发育程度和富水性强弱、煤层的厚度、断层的作用以及4煤与含水层之间隔水层厚度的大小等，是影响工作面涌水的主要因素。研究结果对煤矿砂岩水害的有效防治具有重要的指导意义。 |

| Abstract: | In mining the 4th coal seam in Liuqiao No. 2 Coal Mine, the numbers of water inrushes from Qihan up to 38 times, which affected the coal mining safety seriously. Based on systematical analysis of water inrush from Qihan of Liuqiao No. 2 Coal Mine, the mechanism of water inrush of Qihan is proposed in this paper. That is the control function of fault structure and promoting function of mine pressure. It is pointed out that main factors of water inrush of face are fracture developing degree and watery of sandstone aquifer, thickness of coal seam, fault and aquifuge thickness between the 4th coal seam and aquifer etc.. The conclusion is of great significance for water disaster valid control of sandstone water in coal mine. |
| Keywords: | sandstone aquifer the 7th water bearing bed (Qihan) water inrush mechanism Liuqiao No 2 Coal Mine Huaibei |
