Multi compartment resin and catalyst cartridges - for anchoring mining bolts supported by semi rigid netting and associated spacers

摘要

Adhesive cartridges for anchoring bolts into rock, concrete etc. comprise a series of sealed envelopes contg. alternately complementary filled resin and catalyst/accelerator compsns., enclosed by tubular sheath of rolled semi-rigid netting supported by star-pattern spacers at each end. Used esp. for mounting bolts or studs or even rods inserted using low or negligible rates of rotation (0-150 rpm). The reagents mix more readily than those of a two part container, because of more uniform longitudinal distribution and because of mutual flow of reagents into the interstices of the netting sheath.
