Numerical analysis of fault-slip behaviour in longwall mining using linear slip weakening law

Coal burst induced by fault-slip in longwall mining can adversely influence underground mining activities. This paper analyses the source mechanisms of fault-slip behaviour using a numerical fast Lagrangian analysis of continua in three dimensions (FLAC3D) model. The fault was simulated by the build in zero-thickness interface elements. The post failure process of fault-slip was studied using the linear slip weakening law which was implemented...
