摘要
根据声发射机理,将灰色理论和突变理论相结合,建立声发射参数的灰色尖点突变模型。在刚性试验机上,通过单轴受压岩石破坏全过程进行声发射试验,得到了岩石破坏全过程力学特征和声发射特征,研究岩石破坏规律。利用建立的模型和试验中的声发射参数,对某矿岩爆进行预测,并得到了巷道发生岩爆的声发射参数临界值。
According to mechanism of acoustic emission, this paper sets up grey-cusp catastrophe model of acoustic emission parameter by combining grey theory and catastrophe theory. The mechanical properties of rocks and acoustic emission characteristics are obtained to research failure law of rocks by experiments on acoustic emission （AE） characteristics of full-regime rock failure on stiffness test machine （MTS）. Rock burst of some mine is predicted by model and acoustic emission parameter from experiments. Critical value of acoustic emission parameter of laneway rock burst is obtained.
