Time Evaluation Model for Reasonable Gas Pre-extraction through Drill-holes from Coal Seam being Worked

瓦斯灾害严重影响我国煤矿生产的安全,瓦斯抽放是防止瓦斯灾害事故的根本途径。介绍了钻孔预抽放本煤层瓦斯合理预抽期的影响因素,以及据此而建立的合理预抽期的评价模型。

Gas disasters seriously influence the coal production safety in China coal mines. Gas extraction is the basic way to prevent gas disasters. This paper introduces the factors influencing the period of reasonable gas pre - extraction through drill - holes from coal seam being worked, and thus, establishes the time evaluation model for reasonable pre- extraction.
