Abstract

The invention discloses an opening mining pit or subsidence area bottom water storing and lifting method for mine site rehabilitation. The method is characterized in that the mining pit bottom crack-free groove-shaped state and backfilled waste ore gaps are used for forming a similar underground aquifer; a certain number of opening mining pits are reserved and not filled to serve as temporary storage pits for collecting surface water, surface runoff water in mining pit peripheral collecting areas is collected into the temporary storage pits through the terrain gradient or interception ditches, free settling and filtering, and then the water is laterally collected to the mining pit bottoms through the waste ore gaps, namely filtering layers; and meanwhile underground water on the periphery of the middle-lower portions of the opening mining pits is laterally collected to the mining pit bottoms, an underground water storage reservoir after mining pit filling is formed, and water is lifted through a tube well reserved during filling. The method has the technical advantages that unconcealed water storage in mine site rehabilitation is changed into concealed water storage, stored water evaporation loss is reduced or avoided, the occupied space and potential safety hazards for constructing a square surface water storage pool are avoided, and the effects of retaining water sources and saving lands are achieved.

Description

technical field

[0001] The invention belongs to a novel water source storage method in land reclamation of open pits or mining subsidence, especially for arid and semi-arid areas with large evaporation and natural precipitation that cannot meet the water consumption of cultivated crops after mine reclamation. Background technique

[0002] Mine reclamation refers to the planned remediation of land damaged by excavation, subsidence, and occupation during mine construction and production, so as to restore it to a usable state. In the process of mining, destroying the local ecological balance is the main source of mine environmental problems. Mine reclamation is the main way to solve the mine environment and mine economic development at this stage. At present, land reclamation in mining areas can be divided into agricultural reclamation, forestry reclamation, fishery reclamation, nature protection reclamation, water resource reclamation and industrial reclamation according to it...
