| 摘 要： | 运用一种新的构造煤采样与加工方法,通过大量的试验测定,对比分析了原生结构煤和构造煤的力学特征;定量讨论了主要力学参数间的相关关系,给出了描述煤体破坏状态的分布函数式,并且模拟构成煤与瓦斯突出4个主要能量体之间的相互作用,建立了简化力学模型;从理论上证明了构造煤厚度是煤与瓦斯突出的一个启动因素,讨论了计算其临界值的可能性.

| Abstract: | A sampling and sample preparing method is introduced. The authors comparatively discusseds properties of coal in different structural type, quantitatively analyzes their relationship. Based on these coal mechanical properties, a distribution function of coal destruction is presented, and a simplified model of coal and gas outburst is established, in this model, a specific disturbed coal thickness is considered a trigerring condition for outburst occurrence and its critical value can be theoretically obtained. |
