摘　　要：煤层顶板稳定性问题是煤矿安全、高效生产的重要前提。择优分析影响煤层顶板稳定性的因素,建立了因素集和评价集。引进了模糊数学理论,建立了综合评价煤层顶板稳定性的模型,输出决策结果。得到煤层顶板稳定性位于Ⅱ级较稳定等级,给出了煤层顶板稳定性预测图,为煤矿的开采设计提供了重要的依据。The roof stability of coal seam was an important prerequisite for safe and efficient production of coal mine. Preferred analyzed factors affecting roof stability of coal seam,then established the factor set and evaluation set. A fuzzy mathematical comprehensive evaluation model was introduced to evaluate the roof stability of coal seam, and the stability decision result of coal seam roof was obtained. The roof stability of coal seam was located at a stable level of second grade, and the roof stability prediction chart was given, which provided an important design basis for coal mine mining design.
