Determination of Intervening Pillar Thickness Based on the Cusp Catastrophe Model by Shaowei Ma, Zhouquan Luo, Jianhua Hu, Qifan Ren, Yaguang Qin, Lei Wen

“…For the stability of the intervening pillar of the sublevel drilling open-stope subsequent filling mining method, the multifactor stability mechanical model of the intervening pillar under two different constraint conditions (Model 1 and Model 2) was established based on the elastic thin plate theory. Then, the cusp catastrophe equation and the necessary and sufficient conditions for the instability of the intervening pillar under two different constraint conditions were obtained by using the cusp catastrophe theory. …”
