Review of current practice of early detection of spontaneous combustion at longwall panels

There are many, incidents where the spontaneous combustion of coal in underground longwall panels has resulted in the explosion of methane gas (Qin et al. 2009). The existing spontaneous combustion detection techniques have largely helped the mining industry in the early detection of spontaneous combustion in longwall panels, however, there are several instances when these techniques have failed (Martin & Clough 2021). This paper will inform the current status of spontaneous combustion detection systems in longwall panels based on a literature review and the details research currently being undertaken at Central Queensland University, Australia on the early detection of spontaneous combustion at Longwall Panels.
