Observation on the difficulties in the current development management of abandoned mines

After eight years of unremitting renovation, the company invested nearly 200 million yuan, planting millions of trees and flowers, Lishou Mountain 1400 acres of historical abandoned mines, the restoration of green vegetation area has reached 1039 acres, a change in the past Manshan mine barren scene. The mines have been filled in, the bare mountain has been covered with soil, and the saplings are thriving. After renovation, the landfill is now a botanical garden with evergreen flowers and flowers all over the mountain. It is hard for people to imagine that underneath the mountain was once Pingdu's landfill for more than 20 years.

"After testing, the abandoned mine, which has been restored to green, can fix and adsorb 5,720 tons of sand and dust every year, absorb 34,600 tons of carbon dioxide, and produce 30,658 tons of oxygen, which greatly improves the living environment of Pingdu City, and fully reflects the social value of mine restoration and management." The company chairman Dai Jianqiang introduced that the company through the overall long-term planning and design, according to local conditions to create high-end leisure, sports tourism industry, to give abandoned mines new social value. It is planned to establish an ecological environment restoration and management education base, show the process of restoration and management of abandoned mines, and cultivate citizens' awareness of caring for the environment and participating in environmental protection. The equestrian club, RV camping experience base, basketball court, picking garden and so on have been built, which are welcomed by the public. In the future, according to the plan, tourism supporting projects such as soccer fields, golf driving ranges, ski meadows, RV bases, rock climbing, and mining pit hotels will be built, and high-end health care, education and training, and development training projects have been negotiated.

"In the next five years, the social benefits of the historical abandoned mine management project will be fully launched, and the abandoned mine is transforming into a green water and green mountains that let people remember nostalgia."  Dai Jianqiang said simply.

After on-site investigation, Hu Youyi said very approvingly: "Qingdao Beiyuan Company has opened up a new model of restoring abandoned mines into ecological parks." This model is in the forefront of the country, and has laid the case foundation for the concept of 'abandoned stone mine restoration +' proposed by the China Sandstone Association in combination with the national development direction and enterprise practices. The China Sandstone Association regards Qingdao Beiyuan as a national demonstration enterprise and model, which is to lead the abandoned mines all over the country to develop in this direction and make greater contributions to the construction of the ecological civilization of the country."

"Beiyuan is more creative in the treatment process of abandoned mines, and the case of Licou Mountain is worth studying and promoting." In the treatment of abandoned mines in the sand and gravel industry, the 'Litou mountain model' has played a role of 'pathfinder', from which we can get many Revelations, and relevant governments at all levels should give strong support to such a typical case." Song Shaomin, vice president of China Sandstone Association, director of the Expert Committee, professor of Beijing University of Civil Engineering and Architecture, also gave full affirmation to this abandoned mine management project.

In Sishui County, about 200 kilometers away from Pingdi, the abandoned mine management of Sishui Huifeng Agricultural Development Engineering Co., Ltd. is also in full swing.

There were more than 200 mining and mineral processing enterprises in Sishui County, and the disorderly mining for many years resulted in a serious waste of resources and the destruction of cultivated land, which not only polluted the environment and destroyed the ecology, but also caused prominent contradictions between people and land, damaged farmers' interests, and brought many unstable factors to the society. At the end of 2008, Sishui County strengthened the standardized management of mineral enterprises and closed the iron-bearing gabbro mines, and the thousands of acres of iron-bearing gabbro mining areas left behind have not been effectively controlled.

The company seized the favorable opportunity when the Surabaya County Party Committee and the county government fully implemented the concept of "ecological county" into the "Surabaya Practice" and vigorously promoted environmental protection and ecological construction, actively engaged in the treatment of abandoned mines, established cooperative relations with China University of Geosciences and other well-known universities and scientific research institutions, and launched the land restoration project of Shengshuiyu abandoned mining area in 2011. Adhering to the principles of "land restoration, solid waste utilization, new building materials, sightseeing agriculture, ecological tourism", we set foot on the road of green development of repairing abandoned mines and developing ecological agriculture.
