A dataset of spatial distribution of open-pit mining areas with a resolution of 8 m in the Bohai Rim region(2020-2022)
With the increase of mining activities in China,the ecological environment around mines is facing unprecedented pressure,leading to a series of resource,ecological and environmental problems,such as air pollution,soil erosion,solid waste pollution,landslides and debris flows.To precisely obtain the spatial distribution data of open-pit mining,scholars and regulatory bodies are actively seeking timely and efficient methods to monitor open-pit mining areas by using the remote sensing,an innovative technology,for this purpose.In this research,we adopted high-resolution optical remote sensing image GF-6 with a resolution of 8m to obtain the open-pit mining dataset in the Bohai Rim through rule-based feature extraction,time-series image discrimination and visual interpretation methods,covering over 8000 open-pit mining areas.The dataset exhibits a high level of accuracy,with an overall accuracy of 95.0%,a producer accuracy of 98.0%and a user accuracy of 92.4%.It effectively reflects the spatial dynamics in the distribution of open-pit mining areas within the Bohai Rim region and reveals the influence of economic growth and policy-making on these changes.Thus,the dataset can offer valuable data support for managing open-pit mining operations and the development of related policies.
