"Abandoned unmanned mines used to be a scar of the city, with bare rocks and devastated land everywhere." In the view of Wang Zhongquan, head of the Natural Resources Development and In-situ Conversion Center of Qingzhen Natural Resources Bureau, only through the restoration and management of historical mines can these "scars" gradually heal and make historical mines truly become history.
"You see, the former sand and gravel factory is now planting fresh green leafy vegetables, and we will plant corn and rape in spring." Wang Zhongquan pointed to a vegetable field in the mountain depression in the distance and introduced it to reporters.
From abandoned sand factories to vegetable farmland, the change of Dapo Sand Factory in Lianhua Village is inseparable from a series of measures taken by the local government for the comprehensive management of historical mines.
In the past, the sand factory has formed a steep slope due to the long-term exploitation of limestone. A large number of coarse sand and waste slag are piled up, which is not only very unsightly, but also has great potential geological safety hazards. Since
2021, the local natural resources department has organized relevant departments to formulate plans for 46.989 mu of land in the mining area, implement measures such as land leveling, soil covering and slope consolidation, and reshape the topography and landform. According to the needs of local farmers, irrigation and water storage projects were built, vegetation restoration projects were implemented, and land reclamation and comprehensive utilization were carried out.
In just one year, the once abandoned mines have regained their green vitality, restored their ecology and brought economic benefits to local farmers. Where did the
historical mines come from? According to reports, this part of abandoned mines includes abandoned mines left over from the planned economy period, abandoned mines whose responsible persons are lost or difficult to determine, abandoned mines closed due to policy reasons such as withdrawal from protected areas or capacity removal, and abandoned mines whose responsibility for governance and restoration is clearly assumed by the government when the government makes the closure decision.
In recent years, how to make the historical mines truly become history has become an important issue for the Party committees and governments at all levels to do a good job in the ecological restoration of mines.
Not only the Dapo Sand Factory in Lianhua Village, but since 2021, the Natural Resources Bureau and the Planning Bureau of Guiyang City have made arrangements. Overall deployment of Qingzhen Qinglong Street Office Chen Liangbao Village Qishengpo Sandstone Factory, Bianpo Village Dongjiatianduimenpo Sandstone Factory, Qingzhen Wangzhuang Township Shangyanjing Sandstone Factory, Qingzhen Qinglong Street Office Yongli Sandstone Factory, Qingzhen Xinfa Cement Co., Ltd. Limestone Mine, Future Shale Brick Factory, Qingzhen City Center Shale Brick Factory, The sand and gravel plant of Wanlongda Mineral Development Co., Ltd. in Qingzhen City has a total of 9 historical legacy mines. After preliminary investigation, surveying and mapping, a scientific and reasonable renovation plan has been formulated and implemented according to local conditions.
In the process of restoration and management of mines left over from history, we should use real gold and silver on the edge of the knife, fully respect the suggestions of local residents, adopt the principle of "forest is suitable for forest, farming is suitable for farming, and building is suitable for building", and intensify the renovation of mines left over from history.
Up to now, a total of nine historical legacy mines declared by Guiyang City have been restored and harnessed, all of which are located in Qingzhen City, with a total area of 23.67 hectares restored and harnessed. The restoration and management of mines left over from
history will benefit both the present and the long term. Nowadays, through the restoration and management of historical mines, Guiyang has further eliminated the potential geological hazards of the remaining mines, improved the utilization rate of abandoned land, restored soil vegetation, and people's satisfaction has reached more than 90%.
