Abstract The main mining seam of Huating Mine is Coal 5. Based on the recent hydrogeological supplemental exploration and the analysis of hydrogeological conditions with previous information, the main water-filled factors of mine mining are underground aquifer water and water accumulation in the mining area and roadway. According to its water content, water type and hydraulic characteristics, the aquifer in the mining field was divided into five aquifers, among which the first, second and third aquifers were direct water-filled aquifers, but their water-richness was weak and had little impact on field mining; the hydraulic fissure zone formed after mining of coal 5 layers did not enter the fourth and fifth aquifers, so the fourth and fifth aquifers had little impact on mine water filling if the coal seam was mined normally and the tectonic lot was not developed. The influence of the fourth and fifth aquifers on mine water filling was not significant. In Huating Mine, 2501 mining area was currently mined, and some of the working faces had water accumulation in the goaf due to the influence of face retraction, which needed attention during the mining process.
