摘要
介绍了利用双尾巷治理阳泉三矿K8206大采长综放面瓦斯的试验研究,该试验用了U+Ⅱ型通风方式对大采长综放面工作面瓦斯超限的问题进行了研究,并得出了双尾巷布置的合理位置。在此基础上,运用FLUENT数值模拟软件,针对工作面采用U+Ⅱ型通风方式时采空区瓦斯运移规律进行了数值模拟研究。
This paper introduces the experiment research on double tailing gateways applied to gas control of K8206 super - length fully mechanized top - coal caving face in Yangquan No. 3 Mine. The experiment gives the optimal locality of the double gateways. On this basis, when the different ventilation systems are used in the model test, gas delivery law in goaf is studied by the FLUENT software in this paper There investigation standards are established before gas delivery law in goal being analyzed.
