The method and suggestion of drawing up green mine construction plan

In the planning, the first is to carry out input-output analysis and overall budget for the projects and projects to be carried out, and make overall arrangements in time series according to the priorities; Second, for some small mines or old mines, research and introduction of "advanced applicable technology" that ADAPTS to the economic conditions and development stage of the mine, and promote the transformation and upgrading of process technology and equipment, rather than unbearable "luxury technology"; Third, while clarifying the development direction of comprehensive utilization of resources and circular economy, fully study the market, and consider improving resource and environmental benefits at the same time, there must be a certain economic benefit output as the premise. For example, Chengde vanadium titanium magnetite tailings have stable performance and high strength, which can meet the performance requirements of concrete aggregates, and can provide sufficient and lasting resource guarantee for Beijing green sand and gravel. In some mines with the same resource conditions, but the location conditions and market demand conditions are not very superior, the tailings sand making project is not economically feasible to a certain extent.

2.4 Circulatory system

The construction of green mine is a systematic project, and the construction of green mine is to build the circular economy of mine. The construction of green mine should change the mining enterprises from a single mining mode to a diversified, comprehensive resource development and utilization industry chain development mode. First, it is necessary to establish the concept of circular economy, considering the strengthening of green mining, comprehensive utilization of resources, mining geological environment management +, coupling between multiple production systems or links, so that material and energy multi-level utilization, waste resources and products, waste heat and waste gas energy, forming a multi-level closed-circuit cycle without waste and pollution-free industrial system; Second, it is necessary to establish the concept of comprehensive regulation of "mountains, rivers, forests, fields, lakes and grasses", change the previous narrow concept of land reclamation in mining areas, and through the process of "geomorphic remodeling, soil reconstruction, vegetation reconstruction, landscape reproduction, biodiversity reorganization and protection" from the perspective of "mountains, rivers, forests, fields, lakes and grasses" life community. To realize the "overall protection, systematic restoration and comprehensive management" of the ecological environment in the mining area and the surrounding area.

2.5 Advanced consciousness

As a planner, it is necessary to be forward-looking and innovative in thinking, and make suggestions for the development of mines from a more macro vision and a longer time scale. For example, for new mines, based on the circular economy model from the source, develop technical routes and measures to control interference and damage, strengthen the comprehensive utilization of resources and waste resources, and strive to achieve "no waste" mining without building tailings ponds, no waste rock yards, and no substandard wastewater discharged. For example, the Dawudian graphite mine in Inner Mongolia, in accordance with the concept of green development, in the mine design stage, based on the advantage of "one mine and three resources", to create a green mine of the whole industrial chain, in addition to the development and utilization of main mineral graphite resources, the development of new materials such as high-purity graphite and graphene industries, but also make full use of surrounding rock to develop stone industries such as microcrystalline building materials. Development of assembly building materials industry by using tailings to make foamed ceramics. For open-pit mines that are about to be closed, industrial implantation can be considered while doing a good job in the restoration and management of the mine geological environment. If there are many ways to use abandoned mines at present, + agriculture, cultivation or animal husbandry or aquaculture; + Ecological industries to form reservoirs or wetlands; + Tourism and entertainment, forming mine park, mine hotel; + Social services or other emerging industries, the formation of landfill or photovoltaic power generation, according to the mine's own conditions, regional natural environmental conditions, traffic conditions, distance from the city, local cultural environment, etc., combined with the actual planning to give directional suggestions.

Second, formulate green mine construction planning safeguard measures

1) Strengthen organizational, financial and technical support. Qualified mines should set up a special green mine construction leading group and office, coordinate the relevant work, improve the green mine management system, responsibility system, clear the schedule of planning and implementation, road map, responsible person. The construction of green mines will be included in the production cost budget of enterprises, and actively expand funding channels, strive for green credit and other support, and ensure that the project and project funds are raised and used in place. Strengthen cooperation with universities and research institutes to provide technical support and guarantee for the construction of green mines.
