In-the-hole longhole drill rigs
Sandvik V-30 pushing and pulling reaming packages are designed to be fitted on Sandvik ITH drills DU311-TV, DU311-TVK, DU311, DU411 and DU412i. The V-30 slot raising method uses two ITH hammers mounted on a rigid reaming head body.
Lower risk of failure
Compared to drilled and blasted slot raises, V-30 slot raising has a lower risk of failure, leading to higher productivity.
Fast primary slot development
In comparison to other methods, primary slots can be developed quickly, saving time.
The same ITH longhole drill can be used for production and service hole drilling, meaning less equipment is needed overall.
