Comprehensive Analysis and Drainage Evaluation of Karst Hydrogeological Conditions in the Mining Area
摘要
Abstract
Taking the karst groundwater in Central 1 coal mining area of Gubei Coal Mine in Huainan coal field as the research object,the water level and water quality of the karst aquifer on both sides of the boundary fault of the mining area are compared by using the comprehensive hydrogeological analysis and water release test method.The hydrogeological conditions of the mining area are analyzed,and the hydrogeological model is established to carry out the drainage evaluation.The results show that both F104 and F92 fault groups are water-resisting boundaries,which di-vide the mine into three relatively independent mining area hydrogeological units.The drainage water supply of C3I group limestone in the central mining area mainly comes from the shallow outcrop area,and its hydrodynamic force gradually weakens from shallow to deep along the monoclinal formation.When the total drainage of C3I group is 120 m3/h,the water inrush coefficient is less than 0.06 MPa/m after 60 days,and the water level meets the safety min-ing requirements of coal seam.关键词
