Low-profile drill
J.H. Fletcher says its low-profile HV-32 rotary percussive drill head is designed specifically for roof
bolting applications. The low-frequency high-impact nature of the drill's percussion cycle increases
drilling efficiency in hard-to-penetrate rock. The unit is offered with new roof bolters and as a
retrofit kit, which is fully supported with stock parts.

Percussive
rods and bits
Boart Longyear says its Robust Standard
Thread series of percussive rods and bits
are designed for underground drill and blast
operations. They incorporate a larger crosssectional transition area for a nearly 45percent increase in bending strength, and
the bit skirt is extended for improved interface. This is said to deliver improved impact efficiency
for faster penetration rates, increased rod tip-off resistance, and reduced hole deviation. The series
is capable of interchanging with standard rods and bits.

Customdesigned
conveyor
KPI-JCI's custom-designed overland
conveyor system is available in almost
any width or length, making it ideal
for underground operations. It can be
engineered in conjunction with loading
and unloading systems, stockpiling
systems, and tripper systems.
