Abstract
The procedure is developed for permeability prediction in deep-level fractured coal. Coal permeability and microstructure are experimentally studied on samples taken from the Tikhov Mine. The predictive relationships between the occurrence depth and permeability of coal in parallel to master and side cleavage are obtained for the Nikitinsky, Tambovsky and Tarsminsky fields of the Leninsk geological-economic region in Kuzbass.
