Mechanical Bolts - Minova Global
Minova Mechanical Bolts provide ground control by the suspension method of support. The mine roof is effectively suspended by anchoring the different layers of strata together. Anchorage is accomplished with the assistance of an expansion shell. The Mechanical Bolt is tensioned during installation, which sets the expansion shell against the borehole wall. Mechanical Bolts are offered with a standard expansion shell or bail style expansion shell.
