From sand and gravel plants to vegetable fields, abandoned mines "sell resources" to "sell scenery"

We will innovate mechanisms and explore new models for regulatory operation

The pattern spots involved in the restoration of historical mines are numerous, dispersed, and difficult to supervise on the spot, which is a big problem to be solved.

"Through remote sensing monitoring, we have realized the 'intelligent' supervision of mine restoration data!" At the scene, the staff of the Ecological Restoration Department of the Provincial Department of Natural Resources demonstrated the login of Guizhou Province's territorial ecological restoration - mine ecological restoration supervision platform, relying on high-definition remote sensing images as the base map, to achieve unified, standardized and shared supervision and management of mine ecological restoration.

At present, Guizhou Province uses big data means of "sky observation, ground inspection, staring at management, online management" and "Internet + remote sensing" to monitor the restoration and management of mines. The remote sensing monitoring mode of the whole life cycle of mine geological environment restoration and treatment is adopted, and the surface changes in the target area are extracted by using multi-source and multi-phase remote sensing images to verify the mine restoration and treatment.

At the same time, the establishment of a spot check mechanism, the adoption of conventional and regular remote sensing monitoring, the establishment of a spatio-temporal database to monitor mine restoration, better traceability and supervision of mine restoration and management, to ensure the effectiveness of mine restoration.

"By using remote sensing first and then on-site, we have greatly improved the efficiency of monitoring and supervision, and ensured the effectiveness of mine restoration." Li Songlin said.

In order to speed up the ecological restoration of mines and focus on solving the outstanding problems of mine ecological problems such as excessive historical debts, realistic contradictions, and insufficient investment, combined with the actual situation of Guizhou, in 2020, the provincial Department of Natural Resources issued the Implementation Measures for Guizhou Province to Explore the Use of Market-oriented Ways to Promote the ecological restoration of Mines, exploring the modes of cooperation between the government and social capital and independent investment of social capital. Attract social capital to participate in mine ecological restoration. For example, the Wanshan District of Tongren City uses the landscape resources of industrial relics to realize the new model of "Wanshan mercury mine", which changes from "selling resources" to "selling scenery".

Mine ecological restoration is an important work in the construction of ecological civilization. Guizhou is wielding the pen of green, accelerating ecological restoration and increasing efficiency, ushering in new changes in green development, and historic mines will completely become "history".
