註釋
At the outset of the Project, there was no portable non-contacting technique available for determining the condition of a mine tunnel roof. Such a technique would be of great benefit to Health and Safety in the mining industry as it could allow unsafe roof to be identified without the investigator having to be positioned within the hazardous area. A suitable technique could be of particular use in the cut-out area of a tunnel excavation, prior to support placement, and could facilitate dynamic decision making on the timing of support placement.
