| Abstract: | After analysis, it is pointed out that seam strength, mining depth, seam thickness and support resistance are main influencing factors on breakig result, and the synthesize target appraising breaking result of top coal is set up, thus providing the evidence for forecasting caving result. |
| Keywords: | top coal finite element breaking result breaking coefficient |
