| Abstract: | Based on the results of field observation, simulation model experiment and numerical analysis , the seam conditions that affect the top coal caving and drawing characteristics in the sub-level caving mining are analysed. The critical values,the regularity and sequence of influence of several conditions are put forward. The forecasting formula and the classification for the top coal caving and drawing characteristics of different seams are obtained. |

| Keywords: | seam condition caving and drawing characteristics fractal feature of crack distribution. |
