本文对煤、多孔岩石(砂岩)及裂隙岩石(石灰岩)在不同外载下的渗透率进行了实验研究,得出了不同类型试样的指数型渗透率曲线。本文所做的工作,对于了解煤岩渗流特性,渗流计算,瓦斯涌出量预测以及矿井瓦斯抽放系统设计具有一定参考价值。
In this paper, the permeability of coal, porous rock (sandstone), fractured rock(limestone) varifies with different confining pressure is discussed. Exponential functions between permeability and confining pressure are concluded. As a primary exploratiotion of permeability, it is significant to study coal and rock seepage characteristics and methane emission prediction. It is also useful in mine methane drainage system design.
