摘要

Hydrogeological conditions are very complex in many coal mines in China. Water inrushes from aquifers near mining coal seams occur frequently, and coal mines often suffer from serious water disasters during coal extraction. Therefore, mining safety with regard to groundwater hazards is a common concern of both mine operators and researchers. To calculate inrush flow scientifically in mine pit is the key to the optimum scheme of prevention and cure of the water for the safety production. In this paper, characteristics of heterogeneous fractured media and preferential flow in the media were considered. Based on the principle of dynamics, models on lateral inrush flow in mine pit are proposed to calculate the flux of inrush flow in order to prevent the mine water disaster (as a usual disaster). Compared with traditional large-well models based on Darcy's law, the models are nonlinear, and have clear physical meanings. Results in an example show that the models established in the paper have higher accuracy, and the models are concise, practical. They provide new scientific methods for calculating mine inrush flow.
