Embodiment Construction

[0026] figure 1 Flowchart of the method for determining the location of an underground reservoir provided in an embodiment of the present invention Figure 1 , the invention provides a method for determining the location of an underground reservoir, which includes the following steps:

[0027] Step 110, collect rock mass strength and coal seam burial depth in the underground space of the area to be mined.

[0028] In the above steps, the collection of various parameters is carried out through underground exploration, and the means of underground exploration is mainly geophysical prospecting to obtain the above parameters. The scope and density of the survey can be set according to the topography, geological conditions, etc. and in combination with actual engineering needs.

[0029] Step 120, taking the projection on the horizontal plane of the area where the rock mass strength is greater than the set strength value as the horizontal coverage area of ​​the underground reservo...

Abstract

The invention discloses a position determining method for an underground water reservoir. The method comprises the following steps of: acquiring the rock mass strength and the coal bed burial depth in underground space of an area to be mined; taking the projection of the area with the rock mass strength greater than a set strength value on a horizontal plane as a horizontal coverage area of the underground water reservoir; and taking the lowest position of the coal bed burial depth as the bottom position of the underground water reservoir. According to the position determining method for the underground water reservoir provided by the embodiment of the invention, the spatial position of the underground water reservoir is determined by acquiring the rock mass strength and the lowest position of the coal bed burial depth and the underground water reservoir is subjected to overall layout before mining, so that the defect that the water storage amount is small caused by an improper position of the underground water reservoir is avoided, the utilization rate of water resources is improved, construction projects are reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to water resources protection technology in mining exploitation, in particular to a method for determining the position of an underground reservoir. 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. At the same time, there are abundant coal resources in the western part of our country, but the water resources are scarce, and the water supply in the mining area is in short supply, which affects the production of the mining area. [0003] At present, in order to utilize mine water, the means adopted are usually to filter and treat mine water in the goaf, and then discharge it to the ground. Bu...
