Embodiment 1

[0027] figure 1 It is a schematic diagram of the structure of the distributed underground reservoir group provided by Embodiment 1 of the present invention. Embodiment 1 of the present invention provides a distributed underground reservoir group, which includes more than two underground reservoirs. The underground reservoirs can be located in the same coal seam or It can be distributed in different coal seams; different coal seams are located at different heights, and the various underground reservoirs are connected by diversion pipelines.

[0028] figure 2 It is a flow chart of the method for transferring mine water in an underground reservoir group provided by Embodiment 1 of the present invention. Embodiment 1 of the present invention also provides a method for transferring mine water in an underground reservoir group, which includes the following steps:

[0029] In step a, water diversion pipelines are respectively established between two or more underground reservoirs. ...

Embodiment 2

[0039] When mining a mine, multiple layers of coal seams are often formed, and each coal seam may form multiple underground reservoirs. image 3 The structural diagram of the distributed underground reservoir group provided for the second embodiment of the present invention, the second embodiment of the present invention takes two layers of coal seam as an example to illustrate, as image 3 As shown, the underground reservoir group includes a first reservoir 1 and a second reservoir 2, and also includes a third reservoir 3, wherein the first reservoir 1 and the second reservoir 2 are located at the first coal seam 5 at the same height, and the third reservoir 3 is located at the first coal seam 5 at the same height. The second coal seam 6, the second coal seam 6 is located below the first coal seam 5, and the third reservoir 3 is located obliquely below the first reservoir 1.

Abstract

The invention discloses a distributed underground reservoir group and a transfer method for mine water in the distributed underground reservoir group. The distributed underground reservoir group comprises more than two underground reservoirs; and the underground reservoirs are respectively connected through water conduit pipelines. According to the distributed underground reservoir group and the transfer method for the mine water in the distributed underground reservoir group, which are provided by the invention, the water conduit pipelines are established among the underground reservoirs and are used for transferring, controlling and centrally draining the mine water in the underground reservoirs, and thus underground water is effectively utilized. Meanwhile, as for the underground reservoirs in different coal seams, the underground mine water is transferred during exploitation, and thus the outside drainage of the mine water during exploitation is avoided and the waste is reduced.

Description

technical field [0001] The invention relates to water resources protection technology in mining mining, in particular to a distributed underground reservoir group and a method for transferring mine water in the underground reservoir group. Background technique [0002] my country is a water-short country, and the phenomenon of water shortage poses a threat to the development of the national economy and the improvement of people's lives. In the process of coal mining, mine water will be produced. The discharge of mine water not only wastes a lot of precious water resources, but also easily pollutes the surrounding environment. [0003] Therefore, water retention is usually achieved by establishing underground reservoirs. However, sometimes when mining, the underground reservoir in the mining area has to be extracted, which still causes waste of water resources. Contents of the invention [0004] The invention provides a distributed underground reservoir group and a method...
