【摘要】：為提高煤礦采空區(qū)遺煤可抽采瓦斯量評估的準(zhǔn)確性,利用自主研制的采空區(qū)遺煤殘余瓦斯解吸模擬實(shí)驗(yàn)裝置,模擬密閉采空區(qū)條件下的不同粒徑煤樣瓦斯解吸過程,擬合并推導(dǎo)出遺煤殘余瓦斯解吸速度與時間、粒徑的函數(shù)關(guān)系式,以及遺煤累計瓦斯解吸量經(jīng)驗(yàn)計算公式。驗(yàn)證表明,所推導(dǎo)的遺煤瓦斯解吸公式能夠較好地描述粒徑對實(shí)驗(yàn)煤樣瓦斯解吸規(guī)律的影響,能較好地體現(xiàn)粒徑對煤樣累計瓦斯解吸量變化的影響。
[Abstract]:In order to improve the accuracy of the evaluation of the amount of gas extracted from the residual coal in the goaf of coal mine, a simulated experimental device developed by ourselves is used to simulate the process of gas desorption of coal samples with different particle sizes under the condition of the closed goaf. The relationship between the desorption speed and time, the particle size of residual gas and the empirical formula for calculating the total amount of gas desorption from residual coal are deduced. The results show that the derived formula can better describe the influence of particle size on the experimental coal sample gas desorption law, and can better reflect the influence of particle size on the change of coal sample cumulative gas desorption capacity.
