A contact model for inelastic impact-rebound events such as those that occur when a rock bounces down a slope is developed for dynamic simulations using the discrete element method. Upon impact, the normal contact force follows a linear elastic relationship as a function of relative displacement up to a pre-set transition force, after which the contact(More)
Roadways stability in longwall coal mining is critical to mine productivity and safety of the personnel. In this regard, a typical challenge in longwall mining is to predict roadways stability equipped with a reliable support system in order to ensure their serviceability during mining life. Artificial neural networks (ANNs) were employed to predict the(More)
Detection of leaks of fugitive greenhouse gases (GHGs) from landfills and natural gas infrastructure is critical for not only their safe operation but also for protecting the environment. Current inspection practices involve moving a methane detector within the target area by a person or vehicle. This procedure is dangerous, time consuming, labor intensive(More)
