含瓦斯水合物煤体不同孔隙饱和度试验研究
Experiments on Different Pore Saturation of Coal Containing Gas Hydrate
摘要
Abstract
Coal seam gas solidification and outburst prevention technology uses coal body containing gas hydrate to store large amount of gas and can change the characteristics of mechanical properties of coal body to achieve the purpose of preventing coal and gas outburst. SHW-Ⅲ type test equipment was used for the synthesis test of coal containing gas hydrate at different pore saturation. The result shows that: the acoustic wave velocity of coal containing gas hydrate can indicate the situation of synthesis, and it increases with the increasing of pore saturation. The maximum difference between the predicted and the scheme pore saturation is 4.18% , the maximum difference between predicted and calculated pore saturation is 4.92% ; coal cementability increases with the increase of coal containing gas hydrate pore saturation.关键词
