Problems solved by technology

However, the most significant problem of tailings soil utilization is its large porosity, loose texture, weak water storage capacity, and extremely poor water retention, resulting in physical and chemical properties that are not suitable for the survival of soil animals and plants. the success or failure of
Especially in high-altitude areas, the characteristics of low precipitation, large evaporation, low temperature and drought, and large temperature difference between day and night make it difficult for general water and moisture conservation methods to achieve the desired effect
[0003] Among the relevant patents that have been applied in China, the patent application number is CN201811102129.8 "A Method for Iron Tailings to Soil", adding water-retaining agents and improvers under the surface of iron tailings, and applying microbial agents, and then planting or Cultivated plants have good greening effect and high plant survival rate, but the added water-retaining agent is likely to cause new environmental problems, and the water-retaining time is not long, so the application effect in high-altitude areas is not ideal
The patent application number is CN201910221447.4 "A Method for Soilization of Acidic Tailings", which makes full use of biomass waste such as straw, and at the same time, carbonization promotes thermal weathering of tailings, accelerates soilization of tailings, and speeds up ecological restoration, but Its method of using natural precipitation or artificial watering is not suitable for high-altitude water-scarce areas

Abstract

The invention discloses a tailings soil-based water retention system and a water retention method in a high-altitude area. The tailings soil-based water retention system in a high-altitude area includes a water storage tank, a connecting hose and a capillary action tube. The water retention method includes the steps of digging trenches, embedding capillary action tubes, installation, water injection, backfilling and planting plants. The invention utilizes the principle of capillary action to continuously infiltrate the tailings soil through a water retention system composed of a water storage tank, a connecting hose, and a capillary action tube to maintain the moisture and humidity of the tailings soil, avoiding water loss caused by surface watering, transpiration and infiltration. Resource consumption, large water saving, long-term water conservation and moisture conservation are obvious. While realizing the self-recovery of the tailings soil ecology, the ecological restoration is accelerated, which has the advantages of saving manpower investment and no risk of secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of mine treatment, and in particular relates to a tailings soil-based water retention system and a water retention method in high-altitude areas. Background technique [0002] With the continuous mining and utilization of mineral resources, a large number of mine tailings have been produced. Tailings, also known as tailings, are fine sandy wastes that are discharged after the natural ore is processed by crushing, grinding, sorting and other beneficiation processes, and the useful components in the ore are sorted. The continuous accumulation of tailings not only occupies a large amount of land resources and affects the natural ecological landscape, but also easily pollutes water, air and soil, destroys the ecological environment, and even induces disasters such as collapses, landslides, and debris flows. In high-altitude areas, due to The environment with large evaporation and large temperature changes makes...
