Introduction The “Water Ten Measures,” the “Soil Ten Measures,” and the “Air Ten Measures” have been rolled out one after another. Under the “new normal,” there is tremendous potential for soil remediation and restoration, with abandoned mines emerging as a promising area of focus. Our website recommends an article by Wang Pu, which provides valuable insights into the business opportunities in this field.

The reporter learned from the Aerial Remote Sensing Center of the China Geological Survey that the center, by organizing a nationwide... 32 Home unit, 600 Multiple technicians, following a unified work plan, have completed... 2014 The work of compiling remote-sensing monitoring results on the geological environment of mines nationwide and by province has been completed, yielding a comprehensive set of deliverables—including reports, maps, charts, and data—on the geological environment of mines across the country and in each province (municipality and autonomous region). These national remote-sensing monitoring results for the geological environment of mines were officially submitted recently.

　　The survey results show that nationwide mining development has occupied... 177.50 Ten thousand hectares—the area occupied by currently operating mine developments is approximately... 50.2% The land occupied by the development of abandoned mines is approximately: 45% The area of mines that has been restored and reclaimed is approximately 4.8% 。2014 By the end of the year, the nationwide mine reclamation project has already completed a certain percentage of the national total. 11% is completing a share that accounts for the national total. 14.08% , not yet greened 74.94% Our country has enormous potential for reforestation.

　　The survey results show that the area of mines currently in operation in our country is larger than the area of abandoned mines, while the area of abandoned mines is greater than the area of mines that have already been reclaimed. 9.5 Moreover, the efforts to rehabilitate abandoned mines still need to be strengthened. 2014 Annual, nationwide 30 The total area designated for mining development across provinces, municipalities, and autonomous regions (excluding Hong Kong, Macao, Taiwan, and Shanghai) accounts for approximately [a certain percentage] of the nation's land area. 0.18% Among these, the proportion of land occupied by the mining area is: 40.66% The land occupation ratio of the transit site is: 20.13% The proportion of land occupied by subsidence areas from underground mining (or goaf collapse) is: 15.31% The proportion of land occupied by solid waste is 4.75% The proportion of the area restored and rehabilitated in mining environments is: 4.69% 。

　　The survey results also show that nearly [number] mine-related geological hazards have been identified nationwide. 5000 location. Among these, mining subsidence accounts for the total number of 40.01% Landslides account for the total number of... 27.48% , collapse accounts for the total number of 23.18% — Mudslides account for the total number of... 9.33% Among them, particularly large-scale mining-induced geological disasters account for... 2.84% Large-scale mining geological disasters account for... 8.86% , medium-sized mine geological disasters account for 17.64% , small-scale mining geological hazards account for 70.65% As the data show, geological hazards occur primarily in small-scale mines.

　　It is understood that the findings of this survey belong to... “ Comprehensive Remote Sensing Survey Project for National Land ” Subproject “ National Remote Sensing Monitoring Project for Environmental Impacts of Mineral Resource Development ” , completed under the leadership of the Aerospace Remote Sensing Center.
