【摘要】 煤与瓦斯突出动力效应实验模型必须遵循一定的相似准则才能得到符合要求的模拟结果。已有的突出模拟实验装置大都只是注重煤体的强度和破坏效应,几乎没有考虑突出动力效应的相似条件。本文根据煤与瓦斯突出的动力效应原理,针对模型实验较详细地介绍了突出动力效应模型相似和近似模化的方法,着重探讨了模型的尺度、无限边界,及动力效应的表现条件等几个关键问题,对今后的模型实验研究有一定的参考价值。更多还原

【Abstract】 The experiment model for dynamic effect of coal and gas outburst must follow the certain similarity criterion to get to meet the requirements of simulation results.The past simulation experiment devices mostly just focused on the strength and the destructive effect of coal,almost without considering the similar conditions of outburst dynamic effect.According to the principle of dynamic effect of coal and gas outburst,this paper gave a detailed account of model similarity method and approximate modeling method,and discussed several key problems such as the model scale,infinite boundary and the performance condition of dynamic effect and so on.The results have certain reference value for model experiment study in futurity.更多还原
