摘　　要：煤层顶板稳定性是采煤工作面顶板支护、管理的重要影响因素。在分析木康煤矿主要煤层顶板工程地质特征的基础上,以该煤矿M_2、M_3、M_6、M_8、M_(10)煤层顶板为主要研究对象,通过对煤层顶板岩性、厚度、岩体质量、抗压强度等指标应用模糊综合评判法对顶板稳定性进行综合评判,得出煤层顶板稳定性评价结果。评价结果为煤矿的安全生产提供有效的科学依据。Stability of coal-bed roof is an management of coal face. Based on the analysis important influence factor of the roof support and of engineering geological characteristics of main coal- bed roof, regarding the M2, M3, M6, Ms, M10 main coal-bed roof as research objects, fuzzy comprehensive evaluation of stability of coal-bed roof is done by the evaluating index, such as lithology, thickness, rock mass quality and compressive strength, the evaluation results of coal roof stability is obtained. The evaluation results will provide scientific and effective evidences for safety production of coal mine.
