Study on the effectiveness evaluation method of mine geological environment restoration and governance in Qinghai Province: taking a mining area in Qinghai Province as an example

Green mining in mines is the use of advanced mining techniques to minimize environmental damage caused by mining and promote coordination between mining and environmental protection. In order to promote green mining of mining rights in natural reserves of Qinghai Province and geological environment protection work after mining rights withdrawal, taking a exploration and mining rights project as the research object, selects three indexes including the consistency of landform landscape, the effectiveness of vegetation restoration and management and protection measures in the mining area. A multi-level evaluation system for the effectiveness of geological environment restoration and governance is established. The weighting method is used to assign the weight of evaluation index to each project. Based on GIS platform, the multi-factor synthesis method is used to calculate the effectiveness of geological environment restoration and governance in mining area. Through field investigation and remote sensing monitoring, the problems of geological environment in mining area, the methods and the effectiveness of restoration and governance are discussed and evaluated. The geological environment problem in mine and its influence degree are studied. According to the implementation plan of geological environment restoration and governance, the monitoring and management and protection measures mainly including engineering management, ecological restoration and final management and protection are monitored and evaluated. To find out the current situation of mine geological environment restoration and governance, to monitor the change trend of mine geological environment before and after restoration and governance, to assess the effectiveness of restoration and governance, to formulate acceptance techniques, methods and standards for geological environment restoration and governance after the mining rights withdrawal, to provide support and basis for check and accept of geological environment restoration and governance after the mining rights withdrawal.
