摘　　要：本文在综述煤与瓦斯突出机理的基础上,分析了石门揭煤过程中,巷道煤与瓦斯延时突出机理及其影响因素,并阐述了各种因素在延时突出中的作用。从煤岩体流变方面,阐述了延时突出的产生和停止的原因,并从空间和时间的角度,对石门揭煤过程中巷道煤与瓦斯延时突出整个过程进行了详细的描述。煤与瓦斯突出事故原因及理论分析结果表明,石门揭煤过程中煤与瓦斯延时突出存在两种现象,并且都是地质因素和非地质因素综合作用的结果。研究结果为石门快速揭煤技术的研究,提供理论基础和技术支持。Based on the gas and coal outburst mechanism, the mechanism and effect factors of the gas and coal delay outburst in uncovering coal seam in cross-cut are analyzed detailedly, its process is also described from time and space, and its cause is expatiated from theology. From the accidents causes and theoretical analysis, it is show that the gas and coal delay outburst is the combined action of the geological factors and non-geological factors and there are two phenomena in gas and coal delay outburst. Finally, the action of factors in the delay outburst is expatiated detailedly. The results can offer theoretical and technological support for fast uncovering coal seam in cross-cut.
