Study on Deformation and Failure Characteristics of Surrounding Rock of Overlying Roadway under Upward Mining in the Deep Mine

Abstract: To study the impact of mining of the lower protective layer on the deformation and failure characteristics of the upper roadway, these characteristics of an 879 gas drainage roadway were studied and analyzed during the mining of the II 1051 working face of the Zhuxianzhuang coal mine using similar simulation experiments and numerical simulation methods. The results indicate that with the continuous excavation of the working face, the range of impact of the mining stress gradually spreads and exceeds the level … Show more

“…Experts and scholars at home and abroad have conducted much research concerning the distribution law and damage characteristics of two-way unequal compressive stress fields in the rock surrounding the base plate under the influence of mining in the working face and have achieved remarkable results. Among them are Li Yong'en et al [9][10][11][12]. Given the contradiction between the bottom-pumping lane and the pressurized water, they established a boundary equation for the plastic zone of the circular lane under a twoway unequal compressive stress field, analyzed the damage characteristics of the plastic zone of the surrounding rock in the bottom-pumping lane with the different values of the two-way stress ratio, and determined the reasonable location of the bottom-pumping lane according to the damage characteristics of the plastic zone.…”
