In multi-seam coal mining, the water accumulation in goaf of upper seam will seriously threaten safety lower coal-seam recovery. How to accurately determine charging source and predict amount after a certain time interval has become major challenge that urgently needs be solved production. this study, we consider water-discharging Tangjiahui Coal Mine as object research investigate problem during fully mechanized caving mining extra-thick seams top coal. We used geochemical methods, water-accumulation space large-well methods analyze hydraulic connections between other aquifers, goaf, explore characteristics level changes over time. then results discuss relationship elevation accumulated taken for it fill goaf. The showed there is connection airspace (GW), roof (RW), floor (FW) Ordovician limestone (OW); volume working face was 2,106,838.496 m3. average rate 65.407 m3/h, expected have been filled 32,211.208 h. derived H0=−10−12t3+10−7t2−0.0042t+814.61 (R2=0.9837). This study great significance sustainable development evaluation blocking pillars at mine boundary.
