“…In the field of CBM exploitation, the widely used dual porosity media model is a simplified model derived from Barenblatt's model. In the dual porosity media model, the coal mass is divided into the smallest units, namely, coal matrices, by fractures, and the naturally fractured reservoirs consist of pores in the coal matrices and fractures around the coal matrices (Busse et al, 2014;Connell et al, 2016;Gilman and Beckie, 2000;Thararoop et al, 2012). The adsorbed gas is primarily stored in the pores of the coal matrices.…”

The planning and design of any coal mine development requires among others a thorough investigation of the geological, geotechnical and hydrogeological subsurface conditions. As part of a coal mine exploration program we conducted heat pulse vertical flow meter testing. The flow data were combined with absolute and differential temperature logging data to gain information about the hydraulic characteristics of two different coal seams and their over-and interburden. For the strata that were localised based on geophysical logging data including density, gamma ray and resistivity hydraulic properties were quantified. We demonstrate that the temperature log response complements the flow meter log response. A coupling of both methods is therefore recommended to get an insight into the hydraulic conditions in a coal seam and its overburden.
