| 摘 要： | 利用含瓦斯煤三轴伺服渗流系统,对突出型煤试件进行不同围压的三轴压缩试验。试验结果表明:围压对煤样的弹性模量、峰值强度和变形特性都有一定程度的影响;煤样的弹性模量、峰值强度和变形都随围压的增大而增加。根据以上的研究,围压对煤岩体强度的影响规律和煤岩体的变形特性,对进一步认识含瓦斯煤岩的力学性质具有重要的意义。

| Abstract: | The text made use of three-axis servo filtration system of gassy coal to conduct a triaxial compression test under different confining pressures condition on outburst coal samples.The result showed confining pressure made an effect on modulus of elasiticity,peak intensity and deformation property of coal samples;which increased with the increase of confining pressure.according to the above studies,The effect law of confining pressure on the coal and rock strength and deformation property of coal and rock were of great significance to further understanding of physical properties of gassy coal and rock. |

| Keywords: | triaxial compression test confining pressure peak intensity modulus of elasiticity volumetric strain |
