摘　　要：研究了煤矿顶板运动过程中所表现出的分形特征，提出了用顶板下沉速度、声发射等的分数维值的变化来预报顶板失稳、冒落的方法。不同顶板条件实测结果分析表明，分数维指标能更加科学地反映顶板运动的特性。The authors apply fractal theory to the study of fractal characteristics of roof movement in coal mine and put out the method of using fractal dimension value of roof subsidence and acoustic emission to predict roof unstability and caving. Research to different roof conditions indicates that fractal dimension index can reflect the specific properties of roof movement more scientifically.
