It is so beautiful down there, and the rockbolts decorate the ceiling so beautifully. I could walk for days in those drifts.

Is this grouting?
@Sgana94 5 жыл бұрын
No man, it's not grouted. It is a simple steel bolt that is expanded with compressed air or hydraullic pressure. The pull-out resistence is purely frictional between the bolt and the rock. It is a good, quick and cheap technology, very used in mines. But if you need high capacity bolts it is better to use fully grouted bolts; of course you have to be very careful in the grout mix, but of sure you know better than me the right grouting mix.
