Abstract
Both resin grouted rock bolts and bulk cement grouted rock bolts can now be inserted using the same rockbolting rig. A combination bolting head which allows the operator to decide on the spot which type of bolt to insert has made this possible. All that is needed is a supply of resin cartridges, bags of ordinary Portland cement, the necessary bolts and to follow the correct procedure for inserting each. Drilling the hole, inserting the resin or cement and fitting the bolt or rebar can be achieved using a fully integrated mechanized rockbolting rig operated by one man from under the safety of the previously secured roof section.
