AN ANALYSIS OF MINE WATER INRUSH BASED ON FRACTAL AND NON-DARCY SEEPAGE THEORY

摘要

Mining rock mechanics is a new cross subject of mechanics and mining engineering, the seepage theory is one of the important research directions. This paper combines Wu-fractal/Ergun highspeed flow theory and dynamic system instability, reveals the influence factors of mine water inrush. Research shows that: Mine water inrush related to rock porosity, particle size, shape, fractal dimension, ratio of pore and throat, and other factors. Compared the critical Reynolds number which are got from Wu-fractal model and Ergun equation, Wu-fractal model can reveal more influence factors of mine water inrush than Ergun equation.
