摘　　要：榆神矿区煤层埋藏浅、基岩薄、松散覆盖层厚,是典型的薄基岩、厚积砂松散覆盖层条件下的浅埋煤层,在特殊地层开采条件下,易造成工作面顶板剧烈的矿压显现。文章通过大量现场调查及观测,分析了包含顶板管理状况、煤壁状况、顶板状况、支护条件等4个单元、18项指标的顶板事故影响因素,建立了煤矿顶板事故模糊综合评价模型。通过对榆林矿区4个矿井的分析表明,所建立的模型能较全面地包含该矿区顶板失稳事故的主要内容,能够辨识其致因的安全隐患,为该矿区的保水开采和生态环境保护提供了重要的参考依据。Yu-shen mining area is representative shallow seam for thin bedrock and thick uncon- solidated layers above the roof, the condition of thin bedrock shallow seam especial stratum, the working face bring strong mine weighting. A fuzzy comprehensive evaluation model is set up by mass observation on spot and analysis on the affecting factors of the roof accidents in Yu-shen mining area, involving 18 indicators pertaining to four sections： the control of roof, the stability of coal wall and roof, and the means of support. The research on the roof accidents of four mines in Yu-shen mining area indicates that the model covers the major causes of roof acci- dents in the area. With the application of the model, the important referecnce foundation is provided for the water-preserved mining and environmental protection in Yu-shen mining area.
