STUDY ON THE GROUNDWATER EXPLOITATION AND GEOLOGICAL ENVIRONMENT PROBLEMS IN DAQING CITY

The excessive mining of confined water in a long period causes the continuous decline of groundwater levels in Daqing City, forming the groundwater conical depression. Based on survey data, the main geological environment problems in Daqing City are analyzed. To deal with the groundwater cone of depression, land subsidence, water-type endemic disease, land salinization, lake pollution and other environmental geological problems, the countermeasures are put forward.
