POSSIBILITY STUDY OF FRACTAL FORECASTING OF ROCK CAVING IN COAL MINE
煤矿顶板失稳冒落分形预报的可能性研究

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.
