| 摘 要： | 通过实验的方法对公乌素地区16号煤层煤样注水渗透系数进行测定。研究表明,其渗透系数随体积应力的增加呈负指数规律衰减,随孔隙水压力的增加呈正指数规律增加,随开采深度的增加逐渐减小。研究结果对该地区16号煤层的注水、瓦斯抽放等工程实践具有一定的意义。

| Abstract: | Through experimental methods,the permeability coefficient of water injection into the sample in 16# coal seams in Gongwusu Area was determined.The study shows that the permeability coefficient of the coal masses attenuated in minus exponential law with increasing volume stress,increased in positive exponential law with increasing pore water pressure,and decreased with increasing mining depth.Results of this research can provide certain references to coal seam infusion and gas suction in this region. |
