摘　　要：针对煤矿地下开采带来的地表移动变形和建筑物损害的问题,基于云理论采用Ex、En和He3个数字特征构建采动损害评价云模型对采动影响下地表建筑物损害等级进行科学分析,并以彭庄煤矿为例从倾斜变形、曲率变形和水平变形3个指标对其地表建筑物损害程度有效评价。根据评价云图表明:彭庄煤矿采空区上方建筑物倾斜变形、曲率变形和水平变形3个指标评价云滴均落在等级Ⅰ范围内,即建筑物受到轻微损害,该评价结果与实际情况相互验证,表明了云模型在煤矿采动对地表建筑物损害等级评价中的合理性;与传统评价方法相比云模型具有可视性强、量化等级直观描述等优点,可广泛应用在采动影响下地表损害的科学评价。Aiming at the problems of surface movement deformation and building damage caused by underground coal mining,based on cloud theory,using three digital characteristics of Ex,Enand He,the cloud model of mining damage evaluation is constructed,and the damage level of surface buildings under the influence of mining is analyzed scientifically.Taking Pengzhuang coal mine as an example,from the angle of inclination deformation,energy saving,energy saving and energy saving,analyzes the damage level of surface buildings under the influence of mining curvature deformation and horizontal deformation are effective indexes to evaluate the damage degree of surface buildings.According to the evaluation cloud map,it is shown that the three indexes of inclination deformation,curvature deformation and horizontal deformation of the buildings above the goaf of pengzhuang coal mine fall within the scope of grade I,that is,the buildings are slightly damaged.The evaluation results are verified with the actual situation,which shows that the cloud model is reasonable in the evaluation of the damage level of the buildings on the surface caused by coal mining;Compared with the traditional evaluation methods,cloud model has the advantages of strong visibility and intuitive description of quantitative grade,which can be widely used in the scientific evaluation of surface damage under the influence of mining.
