在多煤层区采煤，上部煤层开采后采空区形成一定的积水，形成了上覆采空区积水，对下部煤层的安全开采会形成威胁，本文分析了神府矿区南梁煤矿2-2煤层开采前后水文地质条件变化，调查计算了采空区积水量，编绘了3-1煤层与2-2煤层之间隔水岩组厚度等值线，预计3-1煤导水裂隙带发育高度25．80～70．17m ，而3-1煤与2-2煤间隔24．14～40．37m ，3-1煤开采发育的导水裂隙带将到达2-2煤采空区，采空区积水将成为3-1煤开采的直接突水水源。

The water collected from upper coal mined area will pose a threat to lower coal mining in the multiple seams area .The paper analyzes the changes of hydrological conditions after the coal seam 2-2 is mined in Nanliang coal mine and calculates the goaf water quantity .We find aquiclude between coal seam 2-2 and 3-1 is changed from 24 .14m to 40 .37m ,it is less than the water suture zone’s height of coal seam 3-1 (25 .80~70 .17m) ,therefore ,goaf water of coal seam 2-2 is the direct source of water inrush for coal seam 3-1 .
