“…Les résultats obtenus du modèle numérique dans lequel le modèle de résistance au cisaillement de Barton est implémenté ont démontré que la rugosité de la surface de la faille affecte grandement l'intensité des ondes sismiques qui émanent du glissement There has been a great demand for mineral resources since the last century due to rapid economic growth in many countries, such as China and India; and it will continue to grow for many years to come so as to supply sufficient resources to all over the world. In order to meet the demand, underground mines have been developed at great depths (Ortlepp, 2000;Sneilling, Godin, & McKinnon, 2013).…”

“…In the field of rock mechanics, the simulation of fault-slip in underground mines has been carried out, aiming at estimating the mechanical properties of faults, evaluating fault-slip potential, and investigating the effect of faults on ambient stress states, albeit the classical Mohr-Coulomb criterion has been mainly used under static conditions (Alber, Fritschen, Bischoff, & Meier, 2009;Hofmann & Scheepers, 2011;Sneilling et al, 2013).…”

“…It is the classical Mohr-Coulomb criterion that is used the most widely for the stability analysis of faults in underground mines (Alber et al, 2009;Hofmann & Scheepers, 2011;Potvin, Jarufe, & Wesseloo, 2010;Sjoberg et al, 2012;Sneilling et al, 2013) because of its simplicity. The failure criterion is expressed as follows:…”

“…In the present study, the following seismic parameters were adopted to investigate dynamic sliding behaviour: seismic moment, Mo, moment magnitude, Mw, and energy released during fault slip, Es. The seismic moment and moment magnitude are commonly used in the study of mining-induced seismicity (Domanski & Gibowicz, 2008;Hedley, 1992;Hofmann & Scheepers, 2011;Sneilling et al, 2013); they are given by…”

“…Many studies have been conducted in order to examine an effect of mining activities, such as extraction of stopes, on the behaviour of faults or shear zones (Alber et al, 2009;Hofmann & Scheepers, 2011;Potvin et al, 2010;Sneilling et al, 2013). The studies have elucidated a relation between the progress of mining sequence and the occurrence of seismic events in terms of cumulative seismic moment, locations and areas of seismic events.…”

Coal remains a primary energy source for the foreseeable future. However, existing approaches for coal exploitation and utilization are highly detrimental to the geological formations from which they are extracted and the atmospheric environment. Moreover, underground mining can induce earthquakes that lead to fatalities and financial losses. The demand to abandon coal mining is increasing worldwide, and the need for efficient, safe, and environmentally acceptable coal exploitation and utilization has garnered widespread attention. We propose a novel unmanned automatic machine‐based mining and in situ conversion method for the safe and clean exploitation and utilization of subsurface coal resources. Solid coal is transformed in situ into fluidized energy resources using this method. To evaluate its effectiveness, a geological model of a coal mine was generated, and a numerical simulation based on the continuum‐based discrete element method was conducted to compare the mining‐induced stress distribution, roof subsidence, coal wall failure, and microseismicity for fluidized and traditional mining methods. Our results indicate that the proposed mining method can significantly reduce damage to the geological formation and greenhouse gas emissions associated with the exploitation and utilization of coal resources. We also discuss the limitations of the current study and future research possibilities.
