Abstract
Based on the previous geological exploration data of Ruifeng Mine,combined with the field investigation,the hydrogeological conditions of Ruifeng Mine were comprehensively analyzed,and the water filling source and way were identified.It was concluded that Ruifeng Mine belonged to karst fissure water filling deposit.The groundwater in the area was mainly recharged by atmospheric precipitation,and the water filling channel was mainly karst fissure,followed by goaf roadway and rock fissure.The comparison method was used to predict the water inflow in the mining area.Combined with the analysis of water filling factors and the calculation of water outburst from the roof and floor aquifers,it was concluded that coal seam mining was mainly affected by the karst fissure water in the Yulongshan section of the Yelang Formation and the Changxing Formation,which was the main threat to coal seam mining.The research results provided reliable hydrogeological bases for the next mining and water prevention and control work in Ruifeng Mine.关键词
