A collaborative research project has been undertaken by Anglo American and CSIRO to develop appropriate strategies for gas and spontaneous combustion management in 6km long panels. Extensive computational fluid dynamics modelling studies have been conducted and calibrated using operational longwall goaf data to obtain a fundamental understanding of goaf gas flow patterns in longwall panels of various goaf lengths and a detailed investigation of the effect of various mining and operational parameters on goaf gas flow patterns. The modelling studies have also been used to investigate the performance of various gas drainage and proactive inertisation strategies during various stages of longwall panel extraction. The details and results of various modelling investigations and recommended strategies for gas and spontaneous combustion management in 6km long panels under modelled field site conditions are presented in this paper.
