HBT Plow Systems
Effective coal extraction in low and medium seam hights
HBT has been designing and building longwall plow systems since 1941 — and things have come a long way. Technical developments since 1990 have once again established plowing as the preferred longwall mining method for low and medium coal seams.
In high and medium coal seams longwall shearers are successfully used throughout the world. However, in coal seams below 1.8 meters down to 0.6 meters height, where there are many of the best coal reserves worldwide, HBT automated plow systems are outperforming shearers.
