高产高效综放工作面瓦斯治理技术与实践

摘要

This paper, by taking 81306 fully mechanized working face in Baode Coal Mine as an example, gave a description of the comprehensive gas prevention and control measures mainly applied in the high-output and efficient fully mechanized caving coal face, including the gas dilution by ventilation, gas drainage by drilling holes along seam, gas drainage from gob, gas drainage by high-level holes, gas control at the upper corner angle and so on. With these measures, the safe mining of the high-output and efficient fully mechanized caving coal face was achieved and the gas problem in the face was solved, this thus provided a certain experience for the gas prevention and control of the similar mines and fully mechanized caving coal faces.%以保德煤矿81306综放工作面为例，介绍了高产高效综放工作面主要采用的通风稀释瓦斯、顺层钻孔抽采瓦斯、采空区抽采瓦斯、高位钻孔抽采瓦斯和上隅角瓦斯治理等瓦斯综合治理技术措施，实现了高产高效综放工作面的安全回采，彻底解决了工作面瓦斯问题，为类似矿井及综放工作面瓦斯治理提供了一定的经验。
