煤层注水防治煤与瓦斯突出机理的研究现状与进展

为了深入研究煤层注水的防突机理,在对国内外煤层注水防治煤与瓦斯突出机理研究的基础上,综述煤层注水影响煤体力学性质、采场应力分布及煤体瓦斯解吸特性3方面的研究现状;进而分析我国在煤层注水防突机理研究方面存在的问题,提出当前应急需解决注水对煤体瓦斯的抑制解吸效应问题。笔者认为:确定抑制解吸效应考察、煤体孔隙特性变化及注水煤样吸附解吸甲烷特性等课题的研究是深入探讨的方向,研究成果为进一步认识煤层注水的防突机理提供理论依据。

Status and Progress of Studies on Mechanism of Preventing Coal and Gas Outburst by Coal Seam Infusion

In order to further investigate the mechanism of preventing coal and gas outburst by coal seam infusion,the researches at home and abroad are summarized,and the research status is discussed in three aspects of infusion affecting coal physical properties,mining field stress distribution and gas desorption characteristics.With the research status,the existing problems and shortcomings in present research are analyzed,the urgent problem needing solving is to study the effect of coal gas desorption by infusion,and the future research directions are coal gas desorption property,coal pore characteristic changes and gas desorption property of infusion coal sample.The achievements provide theoretical basis for further understanding the mechanism of preventing outburst by infusion.
