| Abstract: | In this paper, the authors have studied the mechanics of dynamatic failure problems, that is, instability problems, such as coal burst, roof-floor rock burst, mine earthquake, and coal-gas outburst, which occur in coal mine. The paper has established compressive, tensile, shear and fluid-solid instability models and criteria for coal burst, roof-floor rookburst mine earthquake, coal -gas outburst respectively. |

| Keywords: | dynamic failure in coal mine instability problems the criterion of iustability |
