  • The relationship between aquifers is close in coal mine with complex hydrogeology conditions. It's hard to rapidly discriminate water source of mine inflow by single method. This paper set the working face 2-112 of Ganhe coal mine in Huozhou Coal Electricity Group as an example, a new forcasting method of trend curves is proposed on the basis of analysis of existing methods. The method based on the hydrogeological exploration data constructs intuitive chart-type database, and fully considers hydrological regime change before and after water blow-up. By creating "key irons" and "independent identification zone", the water source was accurately predicted. This method has a notable information rectification ability with low technical requirements and high reliability, may be useful in water abundant mining area.
