Cause analysis on the hazard raising of groundwater level at Lusi village

Through the analysis on the hydrogeology conditions,pumping test,water quality,environment and engineering geological conditions,the cause of hazard raising of groundwater level at Lusi village are identified.The origin of the hazard is the disordered mining of coal pits along a river,and geological and environmental factors are the necessary conditions of the hazard.The analysis provides theoretical basis for the hazard treatment engineering,and is verified by the treatment engineering.
