Document Type and Number:
WIPO Patent Application WO/2020/253264
Kind Code:
A1
Abstract:
Disclosed is a method for constructing a reservoir, segment by segment, at the bottom of an inner-dumping open-pit mine, comprising the following steps: S1, performing end slope treatment, discarding clay at a lowest step of an inner spoil dump in an open-pit mine, and forming a dumping isolation layer; S2, dumping concrete at slopes of the lowest step of end slopes of two sides of the bottom of the mine, and forming an end slope isolation layer; S3, sealing the bottom so as to form a mine bottom isolation layer; S4, dumping aggregate in the open-pit mine; S5, laying a geotechnical cloth, forming a top plate isolation layer so as to complete bottom covering; S6, reusing the clay on the lowest step of an end slope of the inner spoil dump so as to form a reservoir sealing isolation layer; S7, gradually constructing multiple reservoirs in a mining direction of the open-pit mine; S8, performing water resource storage and completing complete installation of a water storage well; S9, completing installation of a water intake well; and S10, performing water resource storage. The method of the invention achieves deep storage of water resources on site, and provides water resources for environmental governance of an open-pit mine.
