Numerical Simulation Study on Influence Factors of the Filling Body Stability in Partial-Filling Mining

Abstract:

There are many factors that influence filling body stability in partial-filling mining. In deep mining, filling rate and internal friction angle of filling body are the main factors that greatly influence both sides of plasticity zone breadth in the process of filling bodys deformation and destruction. Taking filling rate and friction angle as the main variables to make a numerical simulation analysis on the deep mine working face, we can find a conclusion that it shows a concave-down power exponent relationship between the width of plasticity zone and the filling rate; With lower filling rate, it shows a concave-up power exponent relationship with friction angle, and the relationship of power exponent will change into the linearity as the filling rate increase.
