Scope

Scope: This standard stipulates the guiding principles for the assessment of mine ecological restoration, the main content and approaches of ecological restoration, and the evaluation methods and scoring guidelines for various types of outstanding functional units. This standard applies to the engineering construction and management quality standards of mine ecological restoration throughout China; Main technical content: 5.1 Slope management: The instability of slopes is the main cause of geological disasters such as landslides, collapses, and soil and water erosion. This is the first consideration for slope management in abandoned mine ecological restoration. The main work includes: maintaining the flatness of mine roads and making full use of them; carrying out slope modification work, removing dangerous rocks, reducing slope angles, and transforming unformed terraced slopes into water terraces as much as possible to eliminate collapse risks; carrying out greening on treated slopes, planting green plants within the area of the slope to further stabilize it and beautify the environment. 5.2 Treatment of solid waste such as tailings: The solid waste such as tailings, waste rocks, and coal gangue stored in abandoned mines not only occupies land but also damages and pollutes the environment and leads to geological disasters such as debris flows. It must be treated. The main work includes: making comprehensive use of useful components in tailings as much as possible; using advanced technologies and reasonable processes to reprocess tailings to maximally recover useful components; making full use of solid waste such as tailings and waste rocks as raw materials for building materials, including cement, bricks, aerated concrete, cast stone, refractory materials, glass, and foam; and also using them for filling underground or depressed areas and auxiliary roads, thus achieving the ultimate goal of reusing waste materials. 5.3 Development and utilization of remaining
