Mine water inrush path and escape path planning based on simulation platform

Abstract

The underground environment is complex and superimposed with the uncertainty and nonlinearity of the mine water disaster. The situation of water disaster inundation is changeable and difficult to predict. Regarding the difficulty of obtaining the inundation situation in the roadway at various time points during a flood and quickly determining the escape path based on the inundation situation, in this study, the “bucket principle” is used to construct the submergence path tree, determine the direction of the roadway flow bifurcation, analyze the progressive law of the mine water inrush submersion, simulate the water flow in the underground roadway, and visually display the real-time water flow change, water level height and escape path. The research shows that according to the constructed inundation path tree, the water level and other inundation parameters obtained by recursion are used as the basis for designing the escape path. The differential and integral progressive dynamic design of the escape path solves the problem that the optimal escape path cannot be planned in real time due to the complex underground environment and different water inrush conditions at different times.
