Over the last 20 years, roof support technology has mde numerous advance since the original wedge and slotted bolts of the 1950's. By comparison, the roof supports used today are more complex and specialize than the supports used in the past, providing mines with a varied selection of supports from which to choose. As a result, when problems with supports are encountered, it is more difficult to determine whether it is the result of geological changes, poor installation practices, or malfunctioning supports. The purpose of this guide is to provide a logical sequence to resolving the most common problems encountered with of supports.
