|Abstract||During the past twenty years, raise borer manufacturers have continually improved their machines, and users have made advances in their operating techniques. An articulated rod handler relieves the
operator of a heavy and onerous task in adding or removing drill rods. Machine condition monitors can keep a check on oil temperatures and levels, and shut the machine down if limits are exceeded. Reliable economical, carefully programmed controllers
(PLC's) or small computers may be used to aid the operators to reduce maintenance costs, and to increase machine life and availability.|
A computer controlled raise borer was successfully used in 1983, with significant improvements in performance.
Further progress may be made by applying the techniques of expert systems which will provide the correct response to changing machine conditions, or to variable ground, as effectively as a highly skilled operator, but perhaps more quickly.
