This document establishes the objectives, principles, requirements, and workflow for evaluating the degree of harm caused by groundwater aquifer damage in mining areas. It specifies the types of groundwater aquifer damage in mining areas, the manifestations of harm, and the objects affected by harm. It also provides requirements for collecting evaluation data, an evaluation index system, and requirements and content for collecting evaluation indicators. It defines evaluation methods, harm impact grading, comprehensive evaluation, and the presentation of evaluation results. This document is applicable to the investigation, monitoring, and evaluation of the degree of harm caused by groundwater aquifer damage during the mining of weathered and sedimentary deposits. The investigation, monitoring, and evaluation of the degree of harm caused by aquifer damage during the mining of magmatic and hydrothermal deposits can be used for reference.
