39mm Mining Rock Friction Bolt Roof Support for Mine Seam Pipe
39mm Mining Rock Friction Bolt Roof Support for Mine Seam Pipe Product Description
The
friction
stabilization
anchor
is
a
new
type
of
anchor
that
provides
full-length
anchoring
and
active
reinforcement
of
the
surrounding
rock.
It
consists
of
an
anchor
rod
and
a
support.
The
anchor
rod
is
made
of
high-strength
steel
tubing
with
longitudinal
slits.
When
installed
in
a
borehole
slightly
smaller
than
the
tubing
diameter,
the
anchor
rod
immediately
applies
radial
pressure
throughout
the
entire
length
of
the
borehole,
preventing
the
surrounding
rock
from
sliding
downward.
Combined
with
the
support
force
of
the
support,
the
surrounding
rock
is
subjected
to
three-dimensional
stress,
thus
achieving
rock
mass
stability.
