Problems solved by technology

[0003] During the mining process of coal mines, a large amount of mine water will be produced. Direct discharge will not only waste precious water resources, but also cause serious pollution to the environment.
At this stage, the concepts related to mine water resources are not clarified, the basic data are incomplete, the amount of usable water in mine water cannot be estimated, and it is difficult to judge its development and utilization potential, so that coal mine water resources cannot be effectively used
In addition, because there is no mine water utilization method that is adapted to local conditions, that is, to meet the own development and basic conditions of each region, the regional imbalance in the development of mine water utilization has resulted.

Embodiment Construction

[0020] Taking the Majiatan mining area of ​​Ningdong base as an example, a method for utilizing mine water in a coal mine according to the present invention has a calculation period of one year and includes the steps of:

[0021] (1) Obtain mine water gushing volume W inf =680000m 3 , to calculate the amount of mine water resources W 1 As shown in the following formula:

[0022] W 1 =W inf =680000m 3 ;

[0023] (2) Obtain water loss W in mine water treatment loss =30000m 3 , the amount of unavailable water W na = 0, calculate the available amount of mine water W 2 As shown in the following formula:

[0024] W 2 =W 1 -(W loss +W na )=680000-(30000+0)=650000m 3

[0025] Wherein, the mine water availability W 2 It refers to the part of water resources that can be adjusted and utilized through engineering measures and has a certain guarantee rate under the condition of technical feasibility and economic rationality; W 2 , W loss and W na The unit is m 3 ;

Abstract

The invention discloses a coal mine water utilization method. The method comprises the following steps: calculating mine water resource development and utilization potential values according to mine water inflow, mine water treatment loss water quantity, poisonous, harmful and unavailable water quantity, actual utilization quantity in a mining area and actual utilization quantity outside the mining area; And according to the potential value, regulating and storing the mine water discharged from each mining area with the water quality reaching the standard after centralized treatment through aregulating reservoir, and conveying the mine water to an industrial park, a mining area residential area and a mining area ecological park through a pipe network to realize recycling of the mine water. According to the invention, reasonable planning can be carried out according to mine water resource conditions and utilization basic conditions of each region, and the utilization rate of mine wateris greatly improved.

Description

technical field [0001] The invention relates to a method for reusing waste water, in particular to a method for utilizing coal mine water. Background technique [0002] With the continuous development of the resource mining industry, the shortage of water resources has become an important restrictive factor for the economic development of mining areas, and the utilization of mine water is an important measure to alleviate the water shortage in mining areas. [0003] During the mining process of coal mines, a large amount of mine water will be produced. Direct discharge will not only waste precious water resources, but also cause serious pollution to the environment. At this stage, the concepts related to mine water resources are not clarified, the basic data are incomplete, the amount of usable water in mine water cannot be estimated, and it is difficult to judge its development and utilization potential, so that coal mine water resources cannot be effectively used. In addi...
