海域综放工作面通风系统和合理配风量的研究

Study on the ventilation system and the reasonable air distribution in fully mechanized top coal caving working face under sea area

北皂煤矿海域瓦斯涌出量偏大,按高瓦斯矿井管理。虽然采取了瓦斯抽放措施,但由于煤炭自然发火期较短,所以合理选择采煤工作面通风系统,合理优化采煤面配风量成了安全工作的重点。

Beizao coal mine gas emission is larger, management in high gas mine. Although taken the gas drainage measures, but due to the coal spontaneous combustion period is short, so the reasonable choice of working face ventilation system, optimize the working face air distribution became the focus of security.
