Tail ore stock area structure with sewage percolation and resource regeneration

Abstract

The invention discloses a tailings reservoir area structure of seepage and drainage type anti-sewage resource regeneration, which is provided with a base layer, a waterproof board layer, a seepage drainage pipe layer and a geotextile layer from bottom to top; The trimmed pressure groove, above the pressure groove, is provided with a plain concrete pressure roof; the high-density polyethylene boards for waterproofing are lapped by double seam heat sealing with a hot air welder, and the edges are temporarily compressed; gravel is arranged between the rust-proof spring seepage drain pipes Filling material, the surface is a cement mortar permeable consolidation layer, and the vertical surface is also pasted with extruded boards for filling the gaps of seepage and drainage pipes; the geotextiles are lapped with double-sided self-adhesive tapes. It can effectively prevent tailings harmful chemicals, heavy metal elements and water in tailings from invading groundwater in the reservoir area and surrounding rivers, soil and mountains through water, soil media and tailings stacking, achieving a significant effect of tailings pollution prevention. It can prevent pollution and discharge in real time, and can be recycled in real time. It is safe and reliable, with high comprehensive efficiency and low comprehensive cost. The water in the clean water pool can be re-entered into the production link for use.

Description

technical field [0001] The invention relates to the anti-fouling technology of water resources, in particular to a tailings reservoir area structure of seepage and drainage type anti-sewage resource regeneration. Background technique [0002] According to statistics, the total amount of industrial solid waste discharged by the global mining industry every year is tens of billions of tons. In my country, the waste rock tailings discharged by ferrous metal mines are about 620 million tons every year, and the waste rock tailings discharged by non-ferrous metal mines reach 115 million tons every year. , about 130 million tons of coal gangue. The large amount of random discharge of waste rocks and tailings from these mines and the unreasonable layout of the accumulation dam site have seriously damaged the natural ecological environment of land resources. Radioactive substances seriously pollute mining areas and surrounding groundwater, rivers, and farmland through media such as w...
