Problems solved by technology

Regardless of whether it is underground treatment after collection or surface treatment, these two methods are to pump mine water from the stratum space, which actually causes the loss of groundwater, resulting in a continuous decline in water levels, affecting the growth and restoration of the ecological environment

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] A method for distributed utilization of underground water in mines. By storing underground water in mines in goafs that can prevent water seepage, when water is needed, the groundwater is pumped out to the surface through pumping holes for utilization; The way of recharging external water to the water storage space reduces the loss of groundwater and the impact on the growth and restoration of the ecological environment.

[0030] Such as figure 1 Shown, the distributed utilization method of this mine underground water of the present invention comprises the following steps:

[0031] Step 101, surveying the underground space of the mining area to obtain basic geological data of the stratum.

[0032] In practical applications, the survey of the underground space in the mining area includes the survey before coal mining and the survey afte...

Abstract

The invention discloses a distributed using method for mine underground water. The method comprises the following steps of: A, exploring the underground space of a mining area to obtain the basic geological data of a stratum; B, observing well underground water to obtain the flow field distribution situation, water quality data and water pressure data of underground water; C, determining one or more goaf spaces through which underground water cannot pass after coal mining as water storing space(s) of a distributed underground water reservoir according to the obtained basic geological data of the stratum as well as flow field distribution situation condition, water quality data and water pressure data of underground water; D, when a determined water-storing space is formed, enabling underground water generated during coal mining of an adjacent working surface to permeate into the water-storing space naturally; and E, pumping underground water onto the ground surface for using through a water pumping hole which is communicated to the ground surface in each water-storing space when water is required, and refilling external water into the water-storing space when stored water is required to be increased. Due to the adoption of the method, the loss of underground water and the influences on the growth and recovery of the ecological environment can be reduced.

Description

technical field [0001] The invention relates to the field of utilization of underground water resources, in particular to a method for distributed utilization of 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 the sit...
