Abstract

The invention provides a mine water inflow dynamic prediction method and a related device, and the method comprises the steps: obtaining the stratum lithologic parameters of a to-be-predicted mine, and building a geologic structure model of the mine based on the stratum lithologic parameters; generating a mechanical model of the mine based on the geological structure model; generating a water flow model of the mine based on the geologic structure model; the permeability coefficient of the water flow model is adjusted based on the permeability coefficient of the mechanical model, and the water inflow of the mine is predicted based on the adjusted water flow model, so that the defect that hydrogeological parameters in the water flow model are constants is effectively overcome, the predicted water inflow changes along with mining changes of the mine, and the mining efficiency of the mine is improved. And the accuracy of water inflow prediction is improved.

Description

technical field [0001] The present application relates to the technical field of mines, and in particular, to a method and related device for dynamic prediction of mine water inflow. Background technique [0002] It is an important part in the process of mine water hazard prevention and control to explore the variation law of the roof structure and permeability of the mine layer and the prediction of water inflow in the process of mine mining. In the traditional water flow model, mechanical stress and strain are not involved, and the permeability coefficient is generally constant, so it is impossible to simulate and describe the structural variation and parameter changes of the ore roof containment and aquifer, which greatly affects the accuracy of water inflow prediction. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present application is to propose a dynamic prediction method and related device for mine water inflow. [0004] Based on the above ...
