Abstract We propose here a three-zone conceptual model in overlying strata of a longwall panel that accounts for the coupled behaviour of strata deformation and gas flow. The model comprises a fractured gas-interflow zone, a de-stressed gas-desorption zone, and a confined gas-adsorption zone. The fractured gas-interflow zone represents the area where mining-induced cross-strata fractures and bedding separations are well developed with high permeability in both the vertical and horizontal… CONTINUE READING
