高瓦斯煤层群采区巷道布置方式的探讨

Investigation of the tunnel layout way at high gas seam group mining area

结合桃山煤矿的具体情况 ,提出了开采煤层群的高瓦斯矿井采区巷道布置应首先确定合理的煤层分组和煤层开采顺序 ,采区通风系统力求稳定可靠等观点。分析了高瓦斯矿井中采用沿空留巷技术的优越性 ,并对煤层群高瓦斯工作面的通风方式和采用泄排瓦斯巷、尾巷布置进行了探讨。

Combined with the concrete conditions of Taosha n Co al Mine,put forward a layout way of mining high gas seam group mining area,first ,a reasonabl e seam group and system sequence of seam mining should be defined, then,steady a nd reasonable mine ventilation should be done The advantages of the technol og y of leaving roadway along goaf at high gas mine are analyzed And the ventilat i on method,which adopts releasing gas tunnel and tail roadway at high gas seam group face is also approached
