摘要：

In this study, the dynamic nature of coal permeability ahead of a longwall face was addressed. An empirical relationship between the horizontal coal permeability and the vertical stress was established based on the laboratory test data and the simplified field conditions. The derived permeability functions of the front coal seams were applied to a case study of an underground coal mine. The generated data showed good agreement with the field measured data.
