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...

Abstract
The invention discloses a silt removing method for a coal mine underground reservoir. The method includes the following steps that the coal mine underground reservoir is reconnoitered; according to the reconnoitering result, the positions of silt removing openings are determined; silt removing equipment is arranged in the silt removing openings to remove silt of the underground reservoir. Through reconnoitering the coal mine underground water reservoir, the multiple silt removing openings are selected in the positions, where silting-up is prone to happening, of the underground reservoir, the silt removing equipment is arranged to remove the silts, so that a stable water resource adjusting capacity of the underground reservoir is kept, continuous and efficient operation is achieved, it is avoided that because the underground reservoir is silted, the utilization quantity of water resources is small, and a lot of water bodies are closed to cause water burst potential safety hazards, and the reasonable technological method is provided for scientifically regulating and utilizing the coal 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...
