With the continuous decrease of resources, increasingly mining depth, complex mining environment, with water hazard, especially for these small mines, based on this problem, through the analysis of mining situation of multiple small mines in Shahe City, the main water resource in this city was water in the thin-layer limestone (water in Daqing limestone and Benxi limestone), and the water flow was 32 ~572 m3/h. The main water disasters were Ordovician limestone water and goaf water, while water conductive fault and water flowing subsided column were main conducting-water structure of mine. According to the analysis of small coal mines in the area, series of measures to reduce the occurrence of water inrush accidents were put forward to ensure the safe production of the mine.
