对拉炮采放顶煤工作面瓦斯治理实践

Practice of Gas Management in Opposite Pulling Blast Mining Caving Faces

针对对拉炮采放顶煤采煤工作面回采过程中不同瓦斯带,分别采取隅角埋管和高抽巷抽放技术,并适时调整采面通风系统,有效地解决了采面过高瓦斯带期间的瓦斯超限问题,保证了回采的安全生产。

Aimed at different gas district in opposite pulling blast mining caving faces, the high- level gas drainage technology and comer bury the pipe technology are adopted, the ventilation system is adjusted. The gas transfinite problem in high - gas district is solved. The safety production of mining faces is assured.
