Method for storing and lifting water at bottom of subsidence area in mine reclamation

Abstract

The invention discloses a method for storing and lifting water at the bottom of a subsidence area in mine reclamation. The method comprises the following steps of: selecting waste ore with the diameter of 20-50cm for stuffing by utilizing a groove-shaped structure of a crack-free subsidence water pit at the bottom of an open-air mining pit, forming a waste ore layer which vertically penetrates through the subsidence water pit for stuffing in the middle of the subsidence water pit, wherein the distance between the waste ore layer and the adjacent ground is 40-60 cm, and at the moment, two water storage pits are formed in the two sides of the subsidence pit. According to the method for storing and lifting water at the bottom of the subsidence area in mine reclamation, a rock block is placed in the middle of an original subsidence area pit to serve as a base layer, a water storage well consisting of an external pipe is reserved in the subsidence area pit, an inner pipe is arranged in the water storage well, small gravels are stuffed in the water storage well to achieve filtering, and a water pump is effectively prevented from being blocked; and besides, an upper laying layer is arranged at the top of a waste ore stuffing layer, land reclamation planting can be achieved through multi-layer laying design, the water storage pits in the two sides serve as irrigation water sources for planting, planting is facilitated, the drainage and water storage capacity of the two sides is higher, and the effect is more outstanding.

Description

technical field [0001] The invention relates to the technical field of land reclamation, in particular to a method for storing and lifting water at the bottom of a subsidence area in mine reclamation. Background technique [0002] Mine land reclamation, also known as land reclamation, refers to the reclamation of land damaged by excavation, subsidence, etc. during the mine construction and production process in accordance with the requirements of laws and regulations on mineral resources and land management. Actions to restore it to an exploitable state. Mine land reclamation is the method and process of surveying, planning, filling and remediation, development and utilization of land abandoned due to mining. Land destruction and barrenness caused by mining operations is a serious problem in countries all over the world.
