煤与瓦斯突出矿井底板运输巷兼作瓦斯抽采巷设计研究

Design of floor haulage roadway applied as gas drainage roadway in coal and gas outburst mine

通过对富邦煤矿煤层赋存条件、瓦斯涌出规律进行分析,采取了优先开采保护层及底板穿层预抽煤层瓦斯的区域综合防突措施,提出了底板运输巷兼作瓦斯抽采巷的采区布置方式,并对底板穿层钻孔及钻场进行了设计,对今后近距离煤层群的煤与瓦斯突出矿井设计具有参考意义。

This paper analyzes the conditions of coal seam occurrence and gas emission law in Fubang coal mine,to conduct the integrated outbursts prevention measures of protective coal seam mining and gas pre- drainagewith seam-crossing borehole at floor roadway,and introduces mining area arrangement using floor haulage roadway as gas drainage roadway. The study provides reference for the design of coal and gas outburst mine in close distance coal seam group.
