文章以贵州五轮山、玉舍及响水煤矿三层坚固性系数各异的型煤为对象,利用自主研发的三轴渗透仪,进行了不同坚固性系数条件下的恒温-变平均有效应力的三轴渗流实验,实验结果表明相同实验条件坚固性系数与渗透率呈正相关关系,并服从乘幂函数分布,利用实验结论确定了有坚固性系数条件下应力-温度场中的瓦斯运动方程,并以此为基础,建立了含坚固性系数条件下应力-温度场中的瓦斯渗流模型,研究结果对探讨坚固性系数对瓦斯灾害的影响具有较大的理论价值。
Taking briquette with different solidity coefficients of three layers, such as Wulunshan, Yushe and Xiangshui coal mines in Guizhou Province, the article uses the self-developed three-axis infiltrometer to carry out constant temperature-average effective stress under different solidity coefficients The experimental results show that the same experimental conditions have a positive correlation between the solidity coefficient and the permeability and obey the power distribution function. The experimental results confirm the gas equation of motion in the stress-temperature field with the solid coefficient, Based on this, the gas seepage model in the stress-temperature field with the solid coefficient is established, and the research results have great theoretical value to discuss the influence of the solidity coefficient on gas disasters.
