Thinking of China's green mine construction planning in the new era

3.2 Planning concept - Upper antenna + lower ground gas

The idea is the precursor of action. Green mine construction planning concept should not only connect the antenna, but also the ground gas.  Fully embodies "local adaptation, professional technology, economic feasibility, circular system and advanced consciousness".

3.2.1 Local conditions

Different regions, different scales, different production stages (new mines, production mines), different industries, different mining methods, facing different outstanding problems in green mine construction, environmental impact, capital requirements, technical means that should be taken are different. Therefore, in order to make a good plan, we must establish the concept of difference, according to the principle of adapting to local conditions and adapting to the time, one mine and one policy, according to the standard, and carry out targeted planning.

1) Different mining methods: The stripping project of open-pit mine has a large scope, and the construction focuses on solving the problems such as land destruction caused by the pressure of mining pit and external dump, geological disasters induced by the instability of open-pit slope, mining greening, dust suppression and so on. Underground mining mines are faced with problems such as ground collapse, ground cracks and destruction of underground aquifers. The planning focuses on filling mining, water retention mining or integration of mining, selection and charging.

2) Different regions: the terrain, geomorphology, climate and biological conditions around the mine are different, and the difficulty and application of technical modes are different in the mine environmental construction and geological environment restoration; In the warm and moist climate area of south China, the environmental restoration is less difficult, and the focus is on the protection and restoration of biological communities. The western and northern regions are more difficult. For example, Jinhui Mining in Qinghai Province is located in an ecologically fragile region on the plateau, exploring the cultivation of highland barley and other plants on the pulp of the dry beach of the tailings pond, and Dongming Mining in Hulunbuir is located in the east Arctic cold region, selecting and domesticating 26 kinds of seedlings suitable for growth in the cold region.

3) Different scales: Large mines have obvious advantages in team, technology, capital and management, while small mines are at a disadvantage. Large and medium-sized mines should pay attention to comprehensive construction of green mines, not only pay attention to overall resource benefits and environmental benefits, but also pay attention to scientific and technological innovation, personnel training, system construction and other capacity building as well as related ecological industry development, while small mines should focus on environmental restoration standards. Combine their own characteristics to solve specific problems.

4) Different stages: New mines are "incremental planning" mode, equivalent to painting on a blank sheet of paper, to pay attention to systematic and forward-looking; Production mines need to adopt the "stock planning" model, the core is to optimize and upgrade the existing production technology and equipment, economic model.
