摘要：

This paper examines the changes in structure and permeability of coal under the stress conditions experienced around longwall faces. The effect of fracturing is discussed, and the stress-permeability relationship for fractured coal is compared with non-fractured coal. An empirical relationship is derived from experimental data which relates stress-permeability behavior to rank through compressibility of the coal itself.
