Description

Technical Field

[0001] The utility model relates to the field of drainage in mining subsidence areas, in particular to a drainage interception system for hidden subsidence disaster areas in mining areas. Background Art

[0002] Goaf refers to the hollow area formed after the ore in the mine is mined out during the metal mining process. These hollows will cause the collapse of the underground rock formation, thus forming goaf collapse areas.

[0003] Since the drainage area of ​​the mining subsidence area is large, rainwater flowing into the bottom of the subsidence pit may cause mudslide disasters and affect the safe production of mines. It is necessary to prevent the rainwater flowing into the subsidence pit from gathering. It is necessary to install a drainage pump at the bottom of the subsidence area to discharge the rainwater (such as Figure 3 However, rainwater still flows through the entire collapse pit area and gathers at its bottom, which can easily cause mudslides and affect mine safety.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a drainage system for hidden collapse disaster areas in mining areas includes a surface collapse area 1 in the mining area, in which a lower water collection trough 4 and a middle water collection trough 5 for collecting precipitation are arranged from bottom to top, a lifting pump 7 is arranged in the lower water collection trough 4, and the lifting pump 7 conveys the collected water to the middle water collection trough 5 through a water pipe 8, a drainage pump 2 is arranged in the middle water collection trough 5, and the drainage pump 2 discharges the accumulated water to the outside of the surface collapse area 1 through a drainage pipe 3.

[0019] like Figure 2 As shown, an annular open steel trough 6 is provided in the lower water collecting trough 4 and the middle water collecting trough 5. The annular open steel trough 6 not only has better support but also has better sealing performance to prevent rainwater seepage.

[0020] like Figure 2 As shown, the cross section of the annular open steel groove 6 is semicircular and is inclined outward by 60°.

[0021] like Figure 2 As shown, the annular open steel trough 6 is inclined outwardly and divided into a bottom water collection area 61 and a side arc-shaped support area 62. The arc-shaped support area 62 is used to support the slope of the collapsed area. The arc-shaped support area 62 plays a role in supporting the slope to prevent the slope from slipping due to erosion by rainwater.

[0022] The lower water collection trough 4 and the middle water collection trough 5 are arranged in a ring shape along the slope of the surface subsidence area 1 .

[0023] The lower water collection tank 4 is arranged 0.5-1 meter above the bottom of the surface subsidence area 1 .

[0024] The implementation principle of the interception and drainage system for hidden subsidence disaster areas in mining areas in the embodiment of the present application is as follows:

[0025] Rainwater will fall along the surface subsidence area 1 and enter the lower water collection tank 4 and the middle water collection tank 5 at different positions, and the rainwater will be collected by the bottom water collection area 61 of the annular open steel trough 6 in the lower water collection tank 4 and the middle water collection tank 5. The accumulated water in the annular open steel trough 6 of the lower water collection tank 4 will be transported to the annular open steel trough 6 in the middle water collection tank 5 by the lifting pump 7, and the collected rainwater will be discharged to the outside of the surface subsidence area 1 along the drainage pipe 3 through the drainage pipe 3 of the middle water collection tank 5. In this way, water collection and drainage are carried out in sections to avoid the accumulation of rainwater at the bottom of the surface subsidence area 1.

[0026] At the same time, the rainwater collected by the annular open steel troughs 6 in the lower water collection trough 4 and the middle water collection trough 5 will not penetrate along the slope, avoiding slope sliding. Moreover, the arc-shaped support area 62 outside the annular open steel trough 6 tilts outward to play a role in local support of the slope of the surface collapse area 1, thereby preventing large-scale slope sliding and mudslides, thereby ensuring the safety of mining production.

[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
