摘要
Abstract
No.3500 mining area of Liangbaosi Mine was taken as the research object and the stability of the remaining coal pillars in the goaf was studied.Through on-site investigations and data collection,a detailed analysis of the information regarding the mine in the mining area,coal seams,roof lithology,geological structure,and the general situation of the remaining coal pillars were conducted.By applying rock mechanics theory,the vertical stress estimation models of coal pillars were determined.The instability parameters of each remaining coal pillar were calculated,and a comprehensive analysis was carried out considering factors such as overburden movement and the impact of surrounding mining.The results showed that,under the condition of no mining disturbance,there was no risk of instability-induced impact for the remaining coal pillars in No.3 500 mining area.关键词
