摘要

摘要: 為獲取順煤層鉆孔抽放瓦斯的合理參數,依據煤層瓦斯流動理論和質量守恒定律,以順煤層抽放鉆孔周圍瓦斯流場為研究對象,建立了鉆孔抽放瓦斯流動方程的數學模型.以新莊孜煤礦5213掘進工作面為例,采用MATLAB對鉆孔瓦斯流場進行數值模擬,并與礦井的實際抽放情況進行了比較和分析,得出了適合該礦煤層的瓦斯抽放參數.抽放參數可以在淮南礦區相近煤層賦存條件下推廣應用,以利于礦區高瓦斯礦井的安全生產.

Abstract: In order to gain ideal parameters of boreholes along coal seam for methane drainage, based on the gas flow theory in coal seam and the law of mass conservation, a mathematical model of the flow equation for draining methane through boreholes was established to study the methane flow field around drainage boreholes along coal seam. No. 5213 working face of Xinzhuangzi Coal Mine was taken as the field for simulating methane flow with MATLAB software. The simulation result was compared with actual drainage effect of the mine. Finally, the methane drainage parameters suitable to coal seam of the mine were obtained through analysis. The parameters can be applied and popularized in Huainan Mining Area with similar conditions of coal seam storage, which is beneficial to safety production for high methane mines.
