Study on the countermeasures of mining geological environmental protection and restoration and management: taking a gold mine in the southern foot of Qinling Mountains as an example

Aiming at the mining geological environmental problems existing in a gold mine in the southern foot of Qinling Mountain, through data collection and field investigation of the mining geological environment, based on current and predictive assessments of the mining geological environment. This paper analyzes and summarizes the problems of the mining geological environment, and sorted out the types of geologic hazards, the scale, the distribution, the hazardous situation and the development trend. Combined with the actual situation of the mine, it puts forward countermeasures for the prevention and control of mudslide potential, ground subsidence, landslide and tailing pond wastewater. By carrying out the management of geological disaster potential, repairing the damaged topography and geomorphology, re-greening of vegetation, and gradually restoring the function of soil and water conservation in the mining area, the impact caused by the geological environmental problems of the mine can be weakened or reduced to the maximum extent. The study can provide reference and lessons for similar mine restoration and management work.
