针对王家岭煤矿高强度开采对地表建筑物安全构成威胁问题,进行了安全评价研究,提出熵权-模糊综合评价法对地表建筑物安全进行评价,确定包括地表移动变形和建筑物自身属性的评价指标体系;地表移动变形选定为地表下沉、倾斜、曲率和水平变形4种二级指标,建筑物自身属性则细分为建筑物结构、建筑物地基、建筑物建造时间及与工作面的相对关系4个二级指标;采用熵权法确定各指标权重,并构建模糊矩阵,利用模糊综合评价模型对5座建筑物进行了分析。结果表明,王家岭煤矿采动对地表建筑物的影响程度为“一般”,通过实地调研,证实了熵权-模糊综合评价法的科学性和可靠性,为类似工程项目的决策提供了可靠的技术支持。

In view of the threat posed by high-intensity mining in Wangjialing Coal Mine to the safety of surface buildings, a safety evaluation study is conducted. The entropy weight-fuzzy comprehensive evaluation method is proposed to evaluate the safety of surface buildings, and an evaluation index system including surface movement deformation and buildings self attributes is determined; Surface movement and deformation are selected as four types of secondary indices: surface subsidence, inclination, curvature, and horizontal deformation. The self attributes of buildings are subdivided into four secondary indices: building structure, building foundation, building construction time, and relative relationship with the working face; The entropy weight method is used to determine the weights of each index, and a fuzzy matrix is constructed. The fuzzy comprehensive evaluation model is used to analyze 5 buildings. The results indicate that the impact degree of Wangjialing Coal Mine mining on surface buildings is "moderate". Through field research, the scientificity and reliability of the entropy weight-fuzzy comprehensive evaluation method are confirmed, providing reliable technical support for decision-making in similar engineering projects.
