摘要
进行了煤体变形破坏过程实验,利用电液压伺服加载试验、电磁辐射和声发射监测手段,从宏观、细观、微观三个方面对煤样受载破裂过程进行试验研究,分析煤样的裂隙发展速度及其所处的不同的状态,并参照目前的预测方法提出了煤与瓦斯突出危险状态灰色分类方法。
The authors have observed the progress of deformation and destruction of coal bodies in the experiment, carried out the mac- roscopic and microscopic research of the destruction progress of coal samples under load by means of servo electro - hydraulic loading test and electromagnetic radiation and audio emission monitoring, analyzed the cracking rate of coal samples under different situation, investigated the formation and development of cracking by use of fracture and elasticity mechanics, and thus established a sound experimental basis for the prediction by using gray classification .
