摘要： 小煤窑具有开采深度小、采空区分布杂乱无序、隐蔽性高的特点，其分布区构成了一种复杂的破损地质，对工程建设带来重大的安全隐患。为了更加精准探究小煤窑采空区对拟建工程稳定性影响的主要因素，以某电厂小煤窑采空区密集分布场地为工作背景，采用层次分析法（AHP）对此进行分析。构建了12个指标的综合评价指标体系，得出各因素权重并做重要度排序比较，最终辨识确定了小煤窑采空区对拟建工程稳定性影响的主要因素为采空区埋深、建筑物荷载、煤岩柱安全稳定性。结果与工程实践情况基本吻合，为后续小煤窑采空区场地的稳定性评价工作提供了依据。

Abstract: The small coal mines have characterized by small mining depth, disorderly distribution of mined-out areas, and in hidden nature. The distribution area constitutes a complex damaged geology, which brings a great hidden hazard to engineering construction. To explore the main factors of the influence of the abandoned small coal mines on the stability of a proposed project more accurately, this paper takes an abandoned small coal mine of a power plant as the working background and adopts the analytic hierarchy process (AHP) to analyze it. The comprehensive evaluation index system of 12 indexes is constructed, and the weights of each factor are obtained and compared in order of importance. The main factors affecting the stability of the proposed project are the depth of the mine roof, the load of the building and the safety and stability of the coal pillar. The results are generally consistent with the engineering practice. This case history provides a basis for the subsequent evaluation of the stability of the abandoned site of small coal mines.
