Accidents involving falls of roof,
face, and rib in underground mines or falls of highwall in surface
mines, historically, have been among the leading causes of injuries
and deaths. Prevention or control of falls of roof, face, and rib
is uniquely difficult because of the variety of conditions
encountered in mines that can affect the stability of various types
of strata and the changing nature of the forces affecting ground
stability at any given operation and time. Roof and rock bolts and
accessories are an integral part of ground control systems and are
used to prevent the fall of roof, face, and rib. Advancements in
technology of roof and rock bolts and accessories have aided in
reducing the hazards associated with falls of roof, face, and
rib.
