MD320

Former name: ABH 1600
The Sandvik Box Hole Borer is designed as a small TBM for steep inclines.
The MD320 is well suited for short connection holes between the main haulage level and the stope. The holes can be used for ore passes as well as for travel ways or ventilation - or other mine related purposes, where a circular hole with a smooth surface is beneficial.
