Basic Information
Scope
Scope: This document proposes technical requirements for the reconstruction of soil layers at open-pit coal mine tailings piles in arid and semi-arid regions, including the function of the three-layer sponge structure, material composition, and parameters; the use of ground-penetrating radar (GPR) to detect the quality of the reconstructed soil layers; the soil covering process; the layout of runoff cells and supporting projects; and the reclamation of tailings piles. This document is applicable to the reconstruction of soil layers and soil covering processes at open-pit coal mine tailings piles in arid and semi-arid regions. Main technical contents: 1. Reconstruction of tailings pile soil layers; 2. Function of the three-layer sponge structure; 3. Material composition of the three-layer sponge structure; 4. Parameters of the three-layer sponge structure; 5. Detection of the quality of the reconstructed soil layers using GPR; 6. Soil covering process; 7. Layout of runoff cells and supporting projects; 8. Reclamation of tailings piles.
