煤的微观结构对瓦斯放散特性的影响研究

近几年来,我国煤矿的安全生产形势依然严峻,其中煤与瓦斯突出是煤矿井下生产中的一种强大的自然灾害,它严重威胁着煤矿的安全生产,而且随着煤矿开采深度和强度的增加,煤与瓦斯突出问题变得越来越严重。因此为了研究瓦斯突出的影响因素,进行了煤的工业分析、元素分析、煤岩分析[1-2]、显微结构及压汞和瓦斯的放散初速度等实验,对各个影响因素与煤的瓦斯放散初速度耦合影响因素进行分析得出结论。

Research on influence of microstructure of coal on the gas radiation characteristics

In recent years, our coal mine safety production situation is still serious, the coal and gas outburst is a powerful natural disasters in the production of coal mine.It is a serious threat to the safety of coal produc-tion.As the coal mining depth and strength increases, the coal and gas outburst is becoming more and more serious.So in order to study the influence factors of gas outburst, industrial analysis experiment, elemental analysis experiment, coal and rock experiment, scanning electron microscopy experiment and mercury injec-tion experiments and gas irradiation experiment were conducted, then a conclusion from the analysis of the coupling factors using each index parameter to contrast with the initial velocity of gas radiation was drawn.
