ABSTRACT
Virtual reality (VR) simulations provide realistic training environments for safety training and decision-making enhancement. A typical example in tunneling is hazard assessment after blasting. Ground support systems must be installed based on the stand-up time to ensure the safe access of personnel and equipment to the working area. This study presents VR models developed for hazard assessment training in tunneling. The VR simulations involve decision-making tasks to help users learn how to create a safe working environment. First, they are asked to identify the potential hazard around the tunnel face. If the hazard identification is successful, users are requested to install support systems by specifying certain attributes. Finally, participants evaluate the roof fall hazard by examining the displacements around the opening. The initial results indicate that VR is a useful tool for safety training, and have great potential for enhancing decision-making process.
