The overflowed groundwater in Yushui sulfur-copper mine is analyzed,and the rules of karst development in vertical and level direction are studied in the paper.

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.

Prediction of inrush water of mine with pore water yield based on BP artificial neural network;
