With information increasing mechanism in the domain of knowledge discovery,a new proccssing method is proposed,that is the changes in trends analysition of three-matrics(rule s support degree;credibility and sufficiency factors).

based on fully analyzed the hydrogeological condition and mine water filling factors,estimated water conducted fracture zone height activated by the mining of No.

After analyzed the hydrogeological condition and water filling factors in the area,considered that the Jurassic bedded fissure and pore water is the direct water filling source,the Quaternary pore water,gob water and mine drainage are indirect water filling sources.

From the analysis of hydrogeological condition and water filling factors of both mines,predicted normal mine inflow and hazard in Luoyuan minefield through mine inflow comparison and analog method and groundwater dynamic formulae.

In the light of the problem that the shaft water inflow in the capital construction of Zhaozhuang Coal Mine is larger,and connecting with the actual water-inrush in the construction of the shaft,this paper makes directional analysis on the water-filling factors of No.

Taking the example of a coal mine that has been in operation for many years,this paper points out the major water-filling factors of the mine on the basis of the analyzing the hydrogeological characters of the mine.
