Mine management: green mountains will eventually deliver

Efficient utilization of resources, especially the treatment and utilization of "three wastes", is an important content of green mine construction. China Coal Group Datun Company Kongzhuang Coal mine is an old mine, in recent years developed a "pressure fan + bath wastewater" waste heat reuse project. The core technology of the project is sewage source heat pump technology, that is, through the sewage source heat pump unit to do work, the low-grade heat energy into high-grade heat energy, to provide heat for the next day bath hot water, to maximize the recycling of mine waste heat, waste water, coal gangue.

Now, more and more mines are going green.

In 2019, the national green mine catalogue management system began to be implemented, and the enterprises that can be selected in the national list can be described as having passed the five hurdles, and need to meet the 100 specific indicators formulated by the competent department of natural resources, including the assessment of six aspects, such as mining environment, development mode, comprehensive utilization of resources, energy conservation and emission reduction, scientific and technological innovation, enterprise management and image, which is very strict. So far, thousands of mining enterprises have "put on green clothes" and entered the national list of green mines.

Ecological restoration

"Mining and governance", in addition to strengthening green and orderly mining in the production process, for existing mining geological environment problems, in accordance with the current policy, mining enterprises are responsible for the restoration of mining geological environment problems caused by mines under construction and production. The geological environment problems of mines left over or lost by the responsible persons shall be planned and restored by the local governments at all levels, and the central government shall provide necessary financial support.

Swan, egret, grey heron, night heron, heron, anemone, kingfisher... Throughout the year, hundreds of birds appear in the Qingquan Park of Fengfeng Mining area in Handan City, Hebei Province, attracting photography enthusiasts. The water is clear, the bank is green, the beautiful Qingquan park was a large coal mining subsidence area a few years ago. Fengfeng mining district Party Committee responsible person introduced that the mining area is rich in mineral resources, coal chemical industry, steel, ceramics and other industries have had a good time, but the ecological environment has also reached the point of governance. Ban mining and suspend all private stone factories; Repairing coal gangue mountain and treating subsidence area; Building wetlands and parks... After a series of actions, the ecological environment of Fengfeng mining area is getting better and better, and the hat of the heavily polluted area is removed.

In the beautiful Dali Bai Autonomous Prefecture of Yunnan Province, a dilapidated mining area - Batcave area of Jindun Township, Heqing has seriously affected the surrounding environment. Three years ago, MCC Tiangong Group undertook the restoration project of the mine area. The team used the "slope treatment construction process", which is extremely difficult to construct: mechanical blasting on the 30-meter high slope, followed by "mechanical slope repair". At present, the abandoned mine area has been built into a country park with "mountains", "water", "fields" and "parks".

Nowadays, many mines are carrying out the construction of "mining area into scenic spot" : Fengcheng Oilfield in Xinjiang realizes "underground oil production and above-ground tourism"; Duran Jinhui Mining transformed desert Gobi into oasis; Huzhou Wuxingdai River Donghong abandoned mine into a thousand acres of tea mountain......

The "China Mineral Resources Report (2021)" released by the Ministry of Natural Resources shows that the ecological environment of mines in China continues to improve. Since 2020, China has supported ecological restoration of abandoned open-pit mines in key river basins and regions, with the central government allocating 2 billion yuan to support ecological restoration of mines left over from history in the Yellow River basin and the Qinghai-Tibet Plateau in 12 provinces (autonomous regions).
