Abstract

This report descirbes the work undertaken by the Department of Mineral Resources Engineering, University of Nottingham, in the investigation of stress-permeability characteristics of coal measure rocks and the development of CFD based numerical models for the simulation of methane flow through permeable strata around longwall faces. Numerical methods have been developed during the previous project and found to show good promize as a useful tool in the prediction of strata methane flow through permeable strata around longwall faces. The present project has extended the work in order to overcome the limitations of the previous models by conducting both laboratory and numerical research.

major work has been carried out in the investigation of the stress permeability characteristics of both intact and granular coal measure rocks and the development of CFD models for the simulation of methane flow through permeable strata which includes consideration of the waste area behind the face.

Laboratory tests on rock samples in specially designed triaxial permeaters, using advanced pseudo-stiff testing machines, were carried out in order to determine the relationship between stress/permeability and simulate the stress conditions within the front abutment and recompaction zones of a longwall face. Report describing research into stress-permeability characteristics of intact and granular coal measure rocks and the development of CFD based numerical models for the simulation of methane flow through permeable strata around longwall faces, including the waste area behind the face . The project built upon the results of earlier research, which developed numerical methods to predict strata methane flow around longwall coal faces, by conducting further laboratory and numerical research. Laboratory tests on rock samples in specially designed triaxial permeameters, using pseudo-stiff testing machines, were conducted to determine the relationship between stress / permeability and and
