's MT series of roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse cutter heads, these flexible machines can be used for a wide range of applications. They can also be used for rehabilitation of existing tunnels, and excavation of underground caverns.
Roadheaders provide precision within 5 cm, whereas drill-and-blast is on the order of 30 to 35 cm. The more precise the profile is, the more savings are achieved because less shotcrete is required to fill the voids. The precision is made possible by electronic navigation using an external theodolite. A surveyor marks a set point, and …

The R-120, R-130 and R-150 roadheaders were developed to tackle the challenge of increasing the power of the cutter head to expand the capacity to mine rocks harder than coal. Finally, noticing the development limitations of the base model, i.e. the AM-50, the KR-150 medium-weight roadheader was designed.
cutters on roadheaders, as well as other types of mechanical excavators (Ozdemir et al, 1995). The full-scale laboratory tests with a standard transverse cutterhead showed that Mini-Disc Cutters could increase the ability of the roadheaders for hard rock excavation while providing for lesser cutter change and maintenance stoppages.
