摘　　要：为解决矿井水文地质条件复杂矿区的工作面突水后水源难以借助单一方法快速判别的问题,在现有水源判别方法的基础上,以霍州煤电干河矿2-112工作面为例,利用已有勘探数据,提出了以"独立识别区"和"关键离子"为主的用于突水过程分析的水质动态曲线预测法。"关键离子"用于初步判别水源类型,当水质动态曲线进入"独立识别区"时,可进入二级判别确定突水水源。运用此方法实现了对干河矿2-112工作面突水水源的准确判别,形成了肯定判别仅有太灰水或太灰水、奥灰水同时参与突水过程的判别方法。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.
