| Abstract: | Abstract An analysis of a series of chalk samples from the Lublin coal basin reveals that its matrix is a very porous but only slightly permeable porous medium; its water reserves are hardly susceptible to gravity drainage. The interconnected porosity of the chalk matrix diminishes with depth, probably because of the increase in lithostatic pressure. |
