Abstract
This study conducted a stability evaluation of ground collapse in the goaf area of the coal mine in Xinzhou Village,Xiangzhou Town,Tiandong County,Baise City.Multiple methods such as data collection,geological surveys,and on-site visits were adopted to conduct a detailed analysis of the topography,stratigraphic lithology,structures,as well as hydrogeological and engineering geological conditions in the survey area.Through the analysis of parameters such as surface movement and deformation values,mining duration,and classification of roof lithology in the affected area,the following key findings were obtained:The Affected Zone IV shows relatively high values in terms of surface movement and deformation(the maximum slope of 129.27 mm/m,the maximum curvature of 2.65×10⁻3/m,and the maximum horizontal deformation value of 64.02 mm/m).This indicates a high risk of ground collapse in this area.All zones have soft rock roofs,which increase the potential risk of collapse.The study suggests that for high-risk areas(such as the Affected Zone IV),surface deformation monitoring should be strengthened,and protective measures such as grouting reinforcement should be taken;for medium-and low-risk areas,regular monitoring should be carried out and a reasonable mining plan should be formulated.Future research will continue to focus on the long-term effects of surface deformation to ensure the safety and sustainable development of the mining area and its surrounding environment.关键词
