Problems solved by technology
However, in this process, due to the separation of loose gangue and the precipitation of suspended particles, it is easy to cause reservoir siltation, and the siltation state is difficult to observe, which is not conducive to the operation of underground reservoirs, and at the same time poses hidden dangers to underground safety production

Embodiment Construction
[0037] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] Such as figure 1 Shown, the dredging method of coal mine underground reservoir comprises the following steps:
[0039] Step S100: surveying the underground reservoir of the coal mine;
[0040] The step of investigating the underground reservoir of the coal mine further includes:
[0041] Step S101: Investigate the internal and external geological conditions of the underground reservoir and the flow characteristics of the groundwater.
[0042] Preferably, the internal and external geological conditions of the underground reservoir include: the lithological condition of the rock formation where the underground reservoir of the coal mine is located and the structural form of the collapsed gangue in the underground reservoir of the coal mine.
[0043] Preferably, the flow characteristics of the groundwater include: the flow d...

The invention discloses a dredging method for an underground reservoir of a coal mine, which comprises the following steps: conducting survey on the underground reservoir of the coal mine; determining the position of the dredging port according to the survey result; arranging dredging equipment at the dredging port, and Clean up the silt in the underground reservoir of the coal mine. The present invention selects a plurality of dredging outlets at the positions where the underground reservoir is easy to silt through the survey of the underground reservoir of the coal mine, and deploys dredging equipment to remove the sediment, so that the underground reservoir can maintain a stable water resource adjustment capability and realize continuous and efficient operation. To avoid the situation that the utilization of water resources is small due to the siltation of underground reservoirs, and a large number of water bodies are closed to cause water inrush safety hazards, and provide reasonable technical methods for scientific regulation and utilization of mine water resources.
Description
technical field [0001] The invention relates to the comprehensive application of mining engineering and water conservancy engineering, in particular to a method for dredging underground coal mine reservoirs. Background technique [0002] my country is a water-short country, and the shortage of water resources poses a serious threat to the development of the national economy and the improvement of people's lives. Mine water is unavoidable in the process of coal mining. As a precious water resource, the mine water discharged by key state-owned coal mines alone is as high as 2.2 billion tons every year. On average, every ton of coal mined needs to discharge 2 tons of wastewater. On the one hand, the discharge of mine water not only wastes a lot of precious water resources, but also easily constitutes serious environmental pollution to the surrounding environment. On the other hand, there are abundant coal resources in the western region of my country, but the lack of water res...
