Sustainable Mining and Metallurgy

Multi time and multi source domestic high resolution series satellite data from 2018 to 2023 were collected to dynamically monitor the development of mineral resources and the changes of mine geological environment in Dalian. According to high resolution remote sensing data, the geological environment problems of mines in Dalian are mainly concentrated in open pit mines. The mining minerals are mainly limestone, granite, building stone and quartzite. The types of land occupation are mainly transit sites, solid waste and boundary mining. The state of the mine is mostly closed and abandoned by policy. From 2018 to 2023, the area of mine occupation and destruction of land resources and topographic landscape in Dalian showed a downward trend as a whole. Mine geological disasters are decreasing, and the area of mine ecological restoration is increasing year by year. The results of high resolution remote sensing monitoring are more objective and accurate. The research can provide an important basis for formulating scientific and reasonable mine environmental protection measures and promoting the sustainable development of mines.
