Problems solved by technology

[0003] First, the soil structure is damaged and the structure is loose, which can easily cause landslides, and a large amount of silt that has been released has also brought adverse effects on the environment and caused greater safety hazards
[0004] Second, mines that use the in-situ leaching process generally have problems such as steep terrain, unreasonable layout of hole network parameters, excessive liquid injection intensity, strong liquid injection during the rainy season, and unreasonable liquid collection methods, which will damage the crustal structure and slope. Stability, rock mass stress distribution and soil structure
[0005] Third, rock stress changes, rock mass moves, deforms, and is destroyed, and the soil structure is loose, which reduces the strength of the slope. When it exceeds a certain limit, disasters such as slope collapse, landslides, and debris flows are prone to occur, causing secondary damage to the geological environment
[0006] Fourth, it leads to th

Abstract

The invention discloses a water and soil conservation method for an ion-adsorbed type rare earth ore in-situ leaching abandoned mining land. The water and soil conservation method for the ion-adsorbed type rare earth ore in-situ leaching abandoned mining land follows the rules that counter-slope water catchment is conducted, water on a high site is stored on the high site, and storage is conducted before discharging. By the adoption of the water and soil conservation method for the ion-adsorbed type rare earth ore in-situ leaching abandoned mining land, the intensity of water and soil loss is effectively lowered, and erosion to a side slope is lowered; besides, rainwater can be effectively collected and used for plant irrigation, and the harm is turned into good; and in addition, light materials are adopted, the possibility that engineering facilities collapse because of hollowing out caused by the rainwater is lowered, and the practicability and the long service lives of the facilities are guaranteed.

Description

technical field [0001] The invention relates to a soil and water conservation method, in particular to a soil and water conservation method for mining remnants by in-situ leaching of ionic rare earth ores. Background technique [0002] Currently, there are three mining techniques for ion-type rare earth ores: pool leaching, heap leaching, and in-situ leaching. Compared with pool leaching and heap leaching, in-situ leaching is considered to be a more environmentally friendly mining process, but after using in-situ leaching, it still brings the following environmental problems: [0003] First, the soil structure is damaged and loose, which can easily cause landslides, and a large amount of silt that has been released has also brought adverse effects on the environment and caused greater safety hazards. [0004] Second, mines that use the in-situ leaching process generally have problems such as steep terrain, unreasonable layout of hole network parameters, excessive liquid inj...
