摘　　要：本研究针对百色市田东县祥周镇新洲村煤矿采空区进行了地面塌陷稳定性评价。采用资料收集、地质调查、现场访问等多种方法,详细分析调查区的地形地貌、地层岩性、构造以及水文地质和工程地质条件。通过对影响区地表移动与变形值、开采时间、顶板岩性分类等参数的分析,得出以下关键发现:影响区IV在地表移动与变形值方面表现出较高数值(最大斜率为129.27mm/m,最大曲率为2.65×10^(-3)/m,最大水平变形值为64.02mm/m),表明该区域存在较高的地面塌陷风险。所有影响区的顶板岩性均为软岩,这增加了塌陷的潜在风险。研究建议针对高风险区域(如影响区IV)应加强地表变形监测,采取注浆加固等防护措施;对于中低风险区域,应定期监测并制定合理的开采计划。未来研究将继续关注地表变形的长期效应,确保矿区及周边环境的安全与可持续发展。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.
