摘要
为了研究煤矿开采过程中采空区埋管抽采瓦斯条件下自燃"三带"分布规律,以保德煤矿81307综放工作面采空区为研究背景,采用数值模拟和现场实测相结合的方法对其自燃"三带"进行研究。结果表明:81307综放工作面采空区埋管抽采下一号回风巷侧0~175 m为散热带,175~330 m为氧化带,大于330 m为窒息带;运输巷侧0~110 m为散热带,110~265 m为氧化带,大于265 m为窒息带。
To study the distribution law of spontaneous combustion"three zones"under the condition of gas extraction by buried pipe in goaf during coal mining,taking the goaf of 81307 fully mechanized caving face in Baode Coal Mine as the research background,the"three zones"of spontaneous combustion were studied by numerical simulation and field measurement.The research results show that on the inlet side of 81307 fully mechanized caving face,from 0 to 175 m is the heat dissipation zone,from 175 to 330 m is the oxidation zone,and more than 330 m is the asphyxiation zone;on the side of the rubber conveyor,from 0 to 110 m is the heat dissipation belt,from 110 to 265 m is the oxidation zone,and more than 265 m is the asphyxiation zone.
