摘　　要：文章在前人研制的三轴渗流设备及基础上,探讨了将三轴渗流设备出口端气压改造成负压可调节的方法。利用此设备,可以研究瓦斯抽采对煤体瓦斯渗透率的影响。调整实验方案,可以进一步在不同出口负压条件下,研究不同应力场和温度场等因素对煤体瓦斯渗透率的影响。研究成果可为矿井瓦斯灾害防治,提高煤层气抽放水平与煤层气开发利用提供理论依据。Base on the previous research and development on the triaxial seepage equipment, the paper discussed the negative pressure adjustable method reconstructed for the air pressure at the outlet of the triaxial seepage equipment. The equipment was applied to study the gas drainage affected to the gas permeable rate of the coal seam. The adjusted experiment plan could be applied to study the different stress field, different temperature filed and other factors affected to the gas permeable rate of the coal seam under the different negative pressure conditions at the outlet. The study achievements could provide the theoretical basis to improve the coal bed methane drainage level and the coal bed methane development and utilization.
