Structure Characteristics and Its Control Mechanism on Mine Water in Hengyuan Coal Mine

Aiming at the problem that existing geological structure makes mine hydrogeology conditions complicated,on the basis of the tectonic development laws and evolution,the control actions of structure on mining area aquifer formation,groundwater recharge,run-off,discharge and flow field,water chemical composition,mine water burst and water inrush are demonstrated.The water dynamic environment,Karst development features,water inrush features of mining area are rationally explained.Finally,the paper pointed out that small structural fissure under the control of large fault is important regions for preventing mining water in mining area.
