【摘要】：利用三軸滲流實(shí)驗(yàn)裝置,對(duì)新安、新登、演馬3個(gè)礦區(qū)不同類型結(jié)構(gòu)煤的瓦斯?jié)B透率進(jìn)行了研究,得到以下結(jié)論:同一礦區(qū),不同類型結(jié)構(gòu)煤的瓦斯?jié)B透率隨著堅(jiān)固性系數(shù)的增大而增大;Ⅱ類煤瓦斯?jié)B透率受堅(jiān)固性系數(shù)的影響較為明顯,隨著堅(jiān)固性系數(shù)的增加,Ⅱ類煤瓦斯?jié)B透率的增幅是Ⅰ類煤的3倍、Ⅲ類煤的2倍;不同礦區(qū)煤的堅(jiān)固性系數(shù)與不同礦區(qū)煤的瓦斯?jié)B透率沒有必然聯(lián)系;Ⅱ類煤瓦斯?jié)B透率受外部應(yīng)力的影響比Ⅰ類、Ⅲ類煤明顯。
[Abstract]:The gas permeability of different types of structural coal in Xinan, Xindeng and Yanma mining areas was studied by using triaxial seepage experimental device. The following conclusions are obtained: the same mining area, The gas permeability of different types of coal increases with the increase of the coefficient of robustness, and the gas permeability of type 鈪，
