| 摘 要： | 运用岩石破裂分析系统(RFPA2D-Flow)模拟了割缝排放低透气性煤层内瓦斯的过程,验证了割缝排放煤层内瓦斯是降低低透气性煤层煤与瓦斯突出危险的有效方式。同时,数值试验对难以准确监测的煤层内瓦斯压力和瓦斯渗流场的变化规律进行了较好的模拟,为进一步理解瓦斯排放、煤与瓦斯突出机理等提供理论基础和科学依据。

| Abstract: | Using the RFPA^2D - Flow to simulating the process of the gas drainage in low air permeability coal bed by slotting, it prove that slotting is an efficient technique to reduce the risk of coal and gas out bursting. At the same time, the numerical test stimulates the changing laws of the gas pressure and the seepage field in the deep coal. It provides scientific evidence and academic base to the research of gas and coal out bursting and the gas drainage in the low air permeability coalbed. |
