Problems solved by technology

Drainage wells in open-pit mines are generally arranged in remote areas outside the boundaries of open-pit mines, and the layout range and number of layouts are relatively large. After the open-pit mine is mined and internal drainage is realized, if the drainage and drainage wells are cancelled, the shallow groundwater will be restored. Due to the large internal pores of the dump in the open-pit mine, part of the groundwater will infiltrate into the dump, seriously reducing the stability of the dump, and when the amount of infiltration is large, the normal flow of groundwater will be blocked; if the drainage continues , the groundwater level around the mining area will inevitably drop, and the normal migration of groundwater will also be greatly affected. During production, the transportation cost is relatively high

Embodiment 1

[0034] Refer figure 1 For the first embodiment of the present invention, it is provided with an inner discusion type shallow underground water-applying device and a recovery method, and the inner conventional mine shallow underground water take-up device includes a base layer 100, a migration layer 200 and a filter. The layer 300, wherein the base layer 100 comprises an open-air ore end helping 101, a water-sealed layer 102 disposed in the open-air ore end 101, a aqueous layer 103 disposed above the water level 102, provided on the water-water layer 102 and aqueous layer. The artificial portion 104 between 103; the migration layer 200 is disposed above the base layer 100, including the migration passage 201 provided above the manual portion 104, provided in the top-layer portion of the water portion 202 in the migration channel 201; and filtration The layer 300 is disposed above the migration layer 200, which includes the first filter layer 301, the second filter layer 302, the th...

Embodiment 2

[0038] Refer Figure 2 ~ 3 The second embodiment of the present invention, this embodiment differs from the first embodiment is that: when the open pit for the discharge, the space segment 102a stepped surface mines was the abandoned, the row close to the stepped segment 102a, the water in the abandoned open pit easily peeled cement, artificial impermeable layer 104 is connected to both ends to help waterproof layer 102, including internal dump fulfills the discontinuous aquitard. When artificial waterproof layer 104 starts the abandoned hydrophobic blocks of rock, in the migration channel 201, the channel 201 beyond the surface of the surface migration of 2-3m on the original aqueous layer, the job is stopped.

[0039] In the top layer 202 constructing impermeable filter layer 300, and the upper surface of the filter layer 300 within the open pit Dump final design height of the corresponding upper surface flush with the first filter layer 301 to intercept water plant debris and ot...

Abstract

The invention discloses an internal discharge strip mine shallow underground water taking device and a taking recovery method. The internal discharge strip mine shallow underground water taking device comprises a base layer, a migration layer and a filtering layer, wherein the base layer comprises a strip mine end slope, a water-resisting layer arranged in the strip mine end slope, a water-containing layer arranged above the water-resisting layer and an artificial water-resisting layer arranged between the water-resisting layer and the water-containing layer; the migration layer is arranged above the base layer and comprises a migration channel arranged above the artificial water-resisting layer and a top water-resisting layer arranged in the migration channel; the filtering layer is arranged above the migration layer and sequentially comprises a first filtering layer, a second filtering layer, a third filtering layer, a fourth filtering layer, a fifth filtering layer and a water taking well penetrating through the filtering layers and the migration layer from top to bottom; the underground water migration channel is constructed through common mine stripping objects, underground water circulation is recovered, cost is low, and the effect is good.

Description

Technical field [0001] The present invention relates to the technical field of groundwater utilization, and more particularly to a method of visiting the shallow underground water take-up apparatus and a recovery method for disclose a mine. Background technique [0002] During the open-air mine mining, the shallow groundwater (30-50m) around the mine is often drained to avoid groundwater flow into the production area, affecting the production safety. The open-air mine drain-drying well is generally arranged in far away from the outside of the open-air mining area, and the number of arrangements and arrangements are large, and the open-air mine is completed and realized. If you cancel the drainage, the shallow groundwater will recover. Spend, due to the large pores in the open-air mine, some groundwater will penetrate inside the resilings, severely reducing the stability of the resilient restroom, when the infiltration is large, will block the normal flow of the groundwater; if pr...
