摘要
针对目前国内外对煤与瓦斯突出三个无法解释的现象,本文提出采用孔隙瓦斯压力局部化及射流理论来讨论煤与瓦斯突出问题,通过现场观测和数值模拟验证了煤体变形局部化,并把煤作为多孔介质射流模型给出了瓦斯射流的相关计算式和初步估算了发生突出时的煤与瓦斯抛出量和射流流速,对研究煤与瓦斯突出提出了一种新的探讨。
In view of the three problems of coal and gas outburst which can not be explained by the experts, the localization of crack gas pressure and theory of jet are discussed in this paper. And the deformation localization of coal is tested through on-the-spot investigation and numerical simulation. On the other hand, the coal is regarded as a porous material and probed into the jet of coal and gas outburst. In the end, the formulas connected with gas jet are given, and the speed and the quantity of coal and gas outburst are estimated through jet theory. So there will be a novel thought to study the calamity of mining engineer.
