Chinese national-scale dataset of non-metal open-pit mining areas

This dataset, available on Figshare, is the official dataset for the paper titled "Chinese national-scale dataset of non-metal open-pit mining areas." It includes 29,122 vectors that cover approximately 2,986 square kilometers of non-metallic open-pit mining areas across China. Compiled using high-resolution remote-sensing imagery and processed through the YOLOv5 deep learning model, each vector in the dataset delineates various mining-related features such as waste dumps, storage yards, and mining sites. The data is formatted in shapefile format and utilizes the GCS_WGS_1984 coordinate system, ensuring compatibility with geographic information system (GIS) software like ArcGIS, QGIS, R, and Python. This dataset is essential for conducting environmental impact assessments, developing land reclamation strategies, and monitoring ecological restoration efforts related to mining activities in China.

本数据集可于Figshare平台获取，是题为《中国国家级非金属露天矿区数据集》的论文的官方配套数据集。该数据集包含29122个矢量要素，覆盖中国境内约2986平方千米的非金属露天矿区范围。本数据集基于高分辨率遥感影像编制，并通过YOLOv5深度学习模型进行处理，其中每个矢量要素均勾勒出各类采矿相关地物，包括排土场、堆存场及采矿作业区等。该数据集采用形状文件（shapefile）格式存储，并使用GCS_WGS_1984坐标系，可兼容ArcGIS、QGIS、R及Python等各类地理信息系统（GIS）软件。本数据集对于开展中国境内采矿活动相关的环境影响评价、土地复垦策略制定以及生态修复成效监测等工作具有重要支撑价值。
