Problems solved by technology

[0002] Due to the immovability of mineral deposits, serious environmental pollution has occurred during the long-term mining operation of mines, which not only destroyed the regional animal and plant systems, but also caused serious damage to the regional water system structure
[0003] Existing mine environmental governance methods and ecological restoration technologies are usually carried out based on the underground hydrological survey in the slag field area, but the current underground hydrological survey is not intuitive enough and cannot be used for further prediction. It is imperative to establish a three-dimensional numerical model of groundwater in the slag yard area

Abstract

The invention discloses a method for constructing a three-dimensional numerical model of underground water in a mining area. The method comprises the following steps: S100, selecting a water flow model and a solute transport model; s200, performing numerical discretization on the underground water numerical model of the evaluation region by adopting Visual MODFLOW software; and S300, carrying out model identification correction and fitting. The groundwater three-dimensional numerical model of the slag yard area can be established, and the groundwater influence degree of the slag yard area can be predicted.

Description

technical field [0001] The invention relates to the technical field of well drilling, in particular to a method for constructing a three-dimensional numerical model of underground water in a mining area. Background technique [0002] Due to the immovability of mineral deposits, severe environmental pollution has occurred during the long-term mining operation of mines, which not only destroys the regional animal and plant systems, but also causes serious damage to the regional water system structure. [0003] Existing mine environmental governance methods and ecological restoration technologies are usually carried out based on the underground hydrological survey in the slag field area, but the current underground hydrological survey is not intuitive enough and cannot be used for further prediction. Therefore, it is imperative to establish a three-dimensional numerical model of groundwater in the slag yard area. Contents of the invention [0004] Aiming at the problems in t...
