摘　　要：由于采空区围岩质量及其影响因素的复杂性和不确定性,仅根据声发射结果来评判其稳定性往往不尽合理。运用模糊数学的方法,通过建立二级评判模型,综合考虑岩体声发射特性、岩体工程性质、采空区情况和其他影响因素,能更准确地评判采空区围岩的稳定状态。此外,还建立了相关因子的隶属函数,并对其分级界限进行了模糊化处理。结合佛子矿104矿体采空区及其围岩的调查监测情况,对104号矿体采空区进行稳定性综合评价,评价结果与现场实际情况相吻合。Considering the complexity and uncertainty of influ- ence factors and the quality of surrounding rocks in goal, it is not very reasonable to judge the stability solely on the basis of results of acoustic emission. Using the method of fuzzy mathematics to build a twwlevel ewfluation model can get more accurate stability evaluation of surromuling rocks in goal , which take into account the acoustic emission characteristics , rock properties . It also es- tablishes a membership function, which blur the grade bounda- ries. Combined with the actual situation of No. 104 ore-body to synthetically evaluate the stability of goaf, the evaluation findings are consistent with the situation of the mine.
