| 摘 要： | “瓦斯包”压力的突然释放是煤与瓦斯突出的重要原因。文章通过建立一个实体球模型来分析“瓦斯包”作用下的煤体破碎煤块散射过程，从而得到一个能使模型破裂碎散的临界瓦斯压力值，希为控制煤与瓦斯的突出和消除碎煤块的冲击提供量化指标。

| Abstract: | Pressure of the gas pocketabruptly release is an important explanation for the mecha-nism of the coal and gas outburst,The current research will analyze the process of the coal breaking and cracking under gas pocketby building a physical sphere model,then get a critical value of gas pressure that makes the model crack and scatter.This will provide a quantitative indicator which controls the out-burst and eliminates the shock failure of coal sheet. |

| Keywords: | gas pocket coal and gas outburst abruptly release critical value |
