Mine rehabilitation

The parallel exploitation of mineral resources and ecological restoration and management of mining areas is an inevitable requirement of the concept of "ecological priority and green development". Under the guidance of the concept of green development and relying on the spirit of hard work and scientific management, many mines and mining areas in our country are repairing one piece after another of the "scars on the earth", so that the former waste water and mountains have become green mountains.

Recently, Inner Mongolia Erdos City Yijin Horo Banner Wulan Mulun town Tianjiao green energy 500,000 kw coal mining subsidence area ecological governance photovoltaic power generation demonstration project connected to the grid. The implementation of this project provides a new reference for the development of new energy industry, the construction of green mines and the comprehensive development of ecological restoration and management in coal mining subsidence areas in the Yellow River basin.

The parallel exploitation of mineral resources and ecological restoration and management of mining areas is an inevitable requirement of the concept of "ecological priority and green development". Science and Technology Daily reporters visited many places in China and found that the management of mining areas in these areas has achieved remarkable results, and the highlights of ecological restoration are frequent. With the unswerving concept of green development, the spirit of hard work and scientific governance, we are repairing one piece after another "scars on the earth", and the barren mountains of waste water in the past are turning into green mountains.

Work hard, dig out the black and leave the green

In Habahe County, Alatai region, Xinjiang, Ashele Copper Co., Ltd. planted 270,000 trees of various types for the Ashele mining area covered with green clothing, the reporter learned here that since the construction of the mining area began in 2002, the annual spring and autumn tree-planting activities have never been interrupted, this persistence, making the mining area green rate reached 70% today. At the same time, the mining area has also implemented the tailings water utilization project, the domestic sewage purification and pumping, for production water and mining area greening irrigation, to achieve zero discharge of production and domestic wastewater, mine environmental protection management has reached the leading level in China.

Located in Inner Mongolia, the national energy Group Shendong Coal Group Company (hereinafter referred to as Shendong Group) is the only modern energy enterprise in China that delivers 200 million tons of high-quality coal to the country every year. The person in charge of the company introduced: "The 36 years of the establishment of the enterprise is not only the 36 years of building a safe, efficient and modern smart coal base, but also the 36 years of building a green coal base for soil and water conservation, environmental protection and land reclamation; Practice has proved that with firm will and hard work, the ecological environment can be fundamentally improved, and a barren mine can become a green treasure house."

In fact, more than 30 years ago, Shendong Group, while exploiting resources, has already rooted the concept of environmental protection and ecological restoration into the development of enterprises. According to the memories of many old employees of Shendong Group, at that time, we started from the mobile sand area around the mining area, and used the combination of grid sand fixation and irrigation cultivation to fix and control sand. Since 1994, Shendong Group has taken a combination of engineering measures and biological measures to carry out comprehensive soil and water conservation management in small watersheds around the mining area, and the first battle was launched in the Red stone Circle, which was the most serious soil erosion at that time. The workers put up tents on the mountain, slept in the open, and launched a "decisive battle" with the sand area, laying the foundation for today's beautiful "Red stone Circle" in the deep forest.

Wu Jiazheng, an employee of Shendong Group who has 30 years of experience in mining area greening, said: "At that time, the mining area needed a lot of seedlings for afforestation, the supply force around the mining area was insufficient, and the cost of outsourcing was too high, so the group finally decided to grow seedlings by itself." Hard work pays off, in a few years, the group's nursery has cultivated more than 2 million saplings for the mining area. Until today, the nursery is still cultivating seedlings for Shendong Group, which has made a significant contribution to the environmental protection cause of the mining area.

Today, from "a tree" to "a forest", it embodies the firm will of several generations of "Shendong people". The vegetation coverage rate of the mining area of Shendong Group has increased from 3%-11% at the beginning of development to 64% at present, and the ecological control area of the mining area has reached 384 square kilometers.
