Problems solved by technology

Regardless of whether it is underground treatment after collection or ground treatment, these two methods consume mine water from the stratum space, fail to properly preserve water resources, and lead to continuous decline in water levels, affecting the growth and restoration of the ecological environment

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The invention provides a distributed storage method for underground water in mines. By storing the underground water in mines in goafs that can prevent water seepage without extracting the ground, reasonable preservation of groundwater in mines can be achieved, and the impact on the ecological environment can be reduced. Effects on growth and recovery.

[0024] Such as figure 1 Shown, the distributed storage method of this mine underground water of the present invention, comprises the steps:

[0025] Step 101, surveying the underground space of the mining area to obtain basic geological data of the stratum.

[0026] In practical applications, the survey of the underground space in the mining area includes the survey before coal mining and the survey after the formation of the goaf, and the basic geological data of the stratum before mi...

Abstract

The invention discloses a distributed storage method of underground water of a mine. The method includes the following steps: A. prospecting underground space of a mining region to obtain stratal basic geological data; B. observing the underground water of the mine to obtain flow field distribution condition, water quality data and water pressure data of underground water; C. determining one or a plurality of goafs which cannot be penetrated by the underground water to be water storage spaces of a distributed underground reservoir according to the stratal basic geological data obtained in the stepA and the flow field distribution condition, the water quality data and the water pressure data of the underground water and obtained in the stepB; and D. enabling the underground water produced in the coal mining process on the adjacent working face to flow to the water storage spaces naturally in seepage mode when the certain water storage spaces are formed. By means of the method, reasonable storage of the underground water of the mine is achieved, and effects on growth and restoring of ecological environment can be reduced.

Description

technical field [0001] The invention relates to the field of protection and utilization of underground water resources, in particular to a distributed storage method for underground water in mines. Background technique [0002] China 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. Mining underground water is unavoidable in the process of coal mining. The annual discharge of mine groundwater by state-owned key coal mines alone is as high as 2.2 billion tons. On average, every ton of coal mined requires the discharge of 2 tons of wastewater. Like this, not only wasted a large amount of precious water resources, and once the underground water of the mine is discharged outside, it is very easy to constitute serious environmental pollution to surrounding environment. [0003] There are abundant coal resources in western China, but water resources are scarce, and...
