Abstract: Ground support systems consist of surface support that contacts the excavation boundary and a reinforcement system that is embedded into the rock mass. The demand on the components depends on the expected loading conditions from the ground and the type of excavation, being of construction or civil type or rather of mining extraction. The application of ground support materials and methodology is often adapted to meet technical requirements and economics, but this marriage of reason sometimes leads to lessthan-optimal configurations. A review of the combination of existing bolts and accessories from the industry suggested that some design considerations seemed to be overlooked. 
This paper presents the results of an investigation into the overall behaviour of combined bolt and bearing plate elements and the design process that can lead to an optimal support system that is able to handle various loading types from quasi-static to dynamic events. Practical engineering considerations, as well as past and new laboratory data, are presented and discussed. Based on several years of laboratory testing and field applications, the data explores the choice of accessories with various bolt types and strengths, offering a simple approach to quantify the parameters to properly design the ground support system.
