摘　　要：进行地质灾害危险性评估的主要目的是通过揭示地质灾害的发生和发展规律,评价地质灾害的危险性及所造成的破坏损失。矿山生产开采是造成地质灾害发生的主要成因,煤矿地下开采容易引发采空塌陷地质灾害。采空塌陷危险性评估可通过计算导水裂隙带高度,划定塌陷影响范围和使用解析法确定塌陷影响范围,据评估分析来判断采空区影响范围内采空塌陷地质灾害及隐患的发育程度、危害程度、危险性等级,判定建设场地工程建设适宜性、采取何种措施进行防治。根据评估结果,项目工程均位于采空区影响范围外,采空塌陷地质灾害危险性小,适宜项目建设。The main purpose of geological disaster risk assessment is to evaluate the risk of geological disasters and the damage losses caused by revealing the occurrence and development laws of geological disasters.Mine production and mining is a major cause of geological disasters.Underground mining in coal mines is easy to cause geological disasters in goaf collapse.The risk assessment of goaf collapse can be determined by calculating the height delineation of the water conduction fracture zone and using analytical methods to determine the impact range of collapse.According to the assessment and analysis,we can judge the development degree,harm and risk level of goaf subsidence geological disasters and their hidden dangers within the impact range of goaf,and determine the suitability of construction sites and what measures to prevent and control them.According to the evaluation results,the project projects are outside the impact range of the goaf,and the risk of geological disasters in goaf collapse is small,which is suitable for project construction.
