Influence of inner dump on end-slope stability
摘要
Abstract
In order to study the influence of inner dump parameters change on the imbalance ground stress and end-slope stability, based on the development rules of the inner dump steps and the key theory of steep mining, FLAC has been used to simulate the northern end-slope in Haerwusu Open-Pit Coal Mine, and the imbalanced ground stress produced in the process of steep mining and the convergence effect produced by inner dumping have been recorded, then the synergistic effect of the inner dumping on end-slope stability has been analyzed. The results of research show that the inner dump steps can offset the imbalance ground stress well, showing good linear variation law. When the parameters of in-ner dump changes according to one dimensional, the relationship between the slope stability coefficient and the width will accord with quadratic function, and the height accord with linear function. When the parameters change according to three-dimension, the slope stability coefficient performance will be in a good exponential relationship with them.关键词
