Abstract With development of coal industry, continuously extending?depth of mining field, more and more complex gas and geological conditions, as well as increasingly prominent gas control problem, it was clear that the most effective way to control gas in outburst mine was by mining thin layer of Yeqing coal. Based on occurrence characteristics of Yeqing coal seam, fully mechanized matching technology for thin seam under complex conditions of large mining depth and high rock pressure were researched. The practice showed that this technology was advanced and adaptable, which could effectively solved mining difficulty of thin seam, achieved high efficiency mining and obtained good economic and social benefits.
