A method of designing an underground excavation may involve the steps of: Developing a plurality of input parameters for the underground excavation; performing a first design iteration to determine an initial ground support system design; evaluating a kinematic stability of the initial ground support system design; determining whether the kinematic stability meets a predetermined factor of safety; and reiterating the initial ground support system design until the kinematic stability meets the predetermined factor of safety.

A system for determining road quality includes a vehicle equipped with sensors to detect a position of the vehicle on the road and a suspension strut parameter indicative of road quality. The suspension strut parameter may be suspension strut pressure or suspension strut cylinder stroke. A threshold range is established outside of which the suspension strut parameter is associated with poor road quality. A computerized system implementing this method is capable of automating requests for inspection and maintenance of the road, as well as generating maps indicating sections of the road according to their relative quality. The system may be implemented for use by heavy equipment type commonly used in mining operations, or in context of other operations utilizing fleets of vehicles that commonly traverse publicly or privately maintained roads.

A system for optimizing a travel speed of an off-road vehicle utilizes time-over-target values as a threshold indicator for diagnostics and subsequent remedial actions. A road used for haulage is divided into a plurality of predetermined road segments. A target transit time is defined for each of the predetermined segments to provide a target speed curve. An actual transit time values is measured for the off-road vehicle in transiting the road. A comparison outcome is generated by comparing the target transit time value with the actual transit time value. The comparison outcome is useful in diagnosing causes of operation trouble and in scheduling remedial action to address the operational trouble.
