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 ;
