Application of Remote Sensing Technology in Mine Ecological Restoration

Abstract

In the important stage of ecological civilization construction, the ecological restoration of abandoned mines is imminent. Mine geological environment monitoring is the premise of developing mine production, and only comprehensive geological environment data can provide guarantee for mine production. Conventional land resources survey methods have relatively long data cycle and poor accuracy, and can not provide timely, accurate and all-round information. Before the mine ecological restoration, it is necessary to investigate the mine ecological environment, mainly the land use, soil erosion and vegetation coverage of the mine. The application of remote sensing (RS) technology in land survey and dynamic monitoring can grasp the specific situation of land resources in real time, lay a good foundation for land survey and management, and further ensure the timeliness and rationality of land resources. This aricle studies the application of surveying and mapping technology in RS dynamic monitoring of mine geological environment, in order to improve the real-time monitoring of mine, so as to make accurate prediction and minimize the economic losses and casualties in mining areas.

Responses of Soil and Vegetation Properties to Chemical Fertilization in Restoring Coal Gangue Hills in an Alpine Mining Area

“…These open-pit coal mines occupy extensive areas of native marshy wetlands during coal production. The coal gangue, piled up along with frozen underground soil, forms coal gangue hills, creating a unique environmental condition characterized by poor structure, low porosity, a lack of water and nutrient retention capabilities, and de ciencies in essential nutrients required for plant growth (He et al, 2021;Li et al, 2021;Liu et al, 2023). Coal gangue hills have resulted in severe and long-lasting damage to the ecosystem in the high-altitude and cold environment.…”
