In order to ensure the mining working face under pressure to realize safety mining and meet the requirements of the prevention and control of coal mine water regulation, this paper focused on the analysis of aquifer and water-resisting layer and the filling water factors of 5519 working face of a Xingtai Coal Mine. Results show that the Yeqing limestone aquifer, the sandstone aquifer of 5# coal roof and floor and Fuqing limestone aquifer for direct water filling water needs to focus on prevention, and the water inrush coefficient method is applied to the evaluation on the safety of 5519 working face. Results also show that the working face meets the requirements of safety in mining. Ground water prevention measures are implemented to ensure to realize safety mining of 5519 working face. The evaluation result has important referential significance for the similar working face.
