Abstract

There are many factors that influence part-filling pillars’ stability. In deep mining, the main factors are filling rate and the pillar’s internal friction angle that can influence the pillar’s plasticity area greatly in the process of filling pillar’s deformation and destroyment. This paper takes filling rate and friction angle as the main variables to do the numerical simulation. It shows the relationship between the breadth of plasticity area with the fillings rate is power exponential function of adown concave shape. At the lower filling rate, the relationship with friction angle is power exponential function of up-concave shape which will changed into linearity filling rate increasing.
