A PATH TO
Brian Thompson, Joy Global,
explains how the company’s fleet of miner
bolters has helped mines to overcome bottlenecks and improve reliability.
T
he critical path for most longwall installations is
gateroad development. In both single- and
multi-entry gateroad development, when the roof is
weak and early and dense installation of roof bolts
is required, roof support becomes the primary bottleneck and
the longest cycle time event. At the same time, today’s
economic conditions require operators to watch costs without
impacting productivity and safety.
The solution that everyone has been driving towards is a
true simultaneous cut-and-bolt machine for gateroad
development. The machine required is one that can bolt close
to the face and ideally handle dense bolting patterns for both
the roof and ribs, as well as maintaining a high reliability,
while continuing to meet the roadway development
requirements.
Joy Global has a long history of providing solutions to
meet mining’s toughest challenges. Today’s fleet of entry
development machines (miner bolters) has evolved through
years of partnering with mines to address bottlenecks and
improve reliability. This new generation of machines
incorporates the latest developments and technology from
Joy Global, and offers simultaneous cut-and-bolt capabilities.
Entry development solutions
Joy miner bolters are designed for safety, with roof and rib
bolters optionally equipped with dust collection capabilities.
