Open pit treatment and comprehensive utilization method

Abstract

The invention provides an open pit treatment and comprehensive utilization method which comprises the following steps: selecting two opposite side walls in a pit, namely a first side wall and a second side wall, digging an arc-shaped foundation pit in the first side wall, paving a heliostat array in the foundation pit, and arranging the heliostat array in the arc-shaped foundation pit; the heliostat array comprises a plurality of heliostats evenly distributed in the foundation pit, a condensation heat absorption tower and a power generation device are arranged on the ground outside the mine pit close to the second wall, the condensation heat absorption tower is connected with the power generation device, and an ecological system and a projection device are constructed in the mine pit. Compared with heliostats arranged on the flat ground in the prior art, the heliostats are laid in the arc-shaped foundation pit, the height difference exists between the heliostat array and the condensation heat absorption tower, the arrangement number of the heliostats and the construction height of the condensation heat absorption tower are reduced, and therefore the engineering construction cost is reduced, and an artificial landscape with great characteristics is formed; and the projection device is used for projecting a water curtain film, so that the effect of attracting passengers is achieved.

Description

technical field [0001] The invention relates to the technical field of mine pit management, in particular to an open pit mine treatment and comprehensive utilization method. Background technique [0002] The open-pit mine is formed by large-scale human mining. For the large-scale damage to the landform, only the greening measures that cover the surface with vegetation are used, and its effectiveness in restoring the natural landscape is very limited. It is difficult to form a lush vegetation ecosystem that can sustain itself in a natural environment. The depth of the mine pit, the risk of landslides in the soil of the mine pit and other factors make it extremely difficult both technically and economically to build a reservoir to fill the mine pit and to compensate for visual defects with a "lake view". In addition, some open-pit mines are relatively close to densely populated urban built-up areas, and their ecological restoration effects are closely related to the quality o...

[0002] The open-pit mine is formed by large-scale human mining. For the large-scale damage to the landform, only the greening measures that cover the surface with vegetation are used, and its effectiveness in restoring the natural landscape is very limited. It is difficult to form a lush vegetation ecosystem that can sustain itself in the natural environment

Due to the influence of factors such as the depth of the mine pit and the risk of landslides in the soil of the mine pit, it is extremely difficult both technically and economically to build a reservoir to fill the mine pit and use "lake views" to compensate for visual defects.
