摘要
随着煤矿开采深度的加大,煤与瓦斯突出这一灾害日益严重,因此需对突出机理作深入研究。本文综述了瓦斯作用说,化学本质说,地应力作用说和综合假说。指出进一步的研究应把瓦斯因素、煤的物理力学性质和结构特性的影响结合起来,从时间和空间上分析含瓦斯煤岩的强度、形变、流变、集气性和物理化学性等变化规律,最终解决煤与瓦斯突出机理问题,尤其是煤与瓦斯延迟突出机理问题。
With the deepness increase of coal mining, the disaster of coal and gas outburst becomes increasingly serious. Therefore the mechanism of coal and gas outburst should be studied. The current research status of outburst mechanism such as gas effect theory, chemistry essence theory, ground stress effect theory and synthesis theory are summarized in this paper. It is pointed that future research should aim at the following aspects including combining gas factor with physics mechanics and structure properties of coal, analyzing the rules of intension, shape change, flow change, accumulating gas and physical chemical characteristics of coal gas and rock from space and time. The mechanism of coal and gas outburst and delay outburst especially will be accounted for ultimately.
