Face Master 2.1 drilling rig - from the show directly to the job site

Our Face Master 2.1 arrived in Almaty in Kazakhstan for the Mining Metals Central Asia exhibition. For three days the visitors had a chance to have a closer look at this machine for narrow vein drilling. After the show it goes directly to the job site in a gold mine.

Due to limited space in production headings, kinematic of working unit has to be ready for face drilling as well as vertical long-hole drilling with quick reset of the feeder position. The Face Master 2.1 is equipped with well proven design of heavy duty 2-axial rotary actuator, where changing the position from horizontal to vertical is extremely easy in limited area of tight heading. Additional dump cylinder improves the correction fore and aft movement during vertical drilling, match direction of vertical drilling in accordance with vein deposit.

Narrow dimensions of the machine may cause problems with stability during tramming and drilling, but this problem is also solved by other design idea, proven on low profile machines. Central oscillated vertical main pivot changed the tyre load distribution and increase stability during tramming on uneven roads and headings. Drilling process requires high stiffness of the carrier as can be achieved by rigid chassis, Mine Master implemented state-for-the-art solution, to convert flexible, oscillated carrier to rigid module.
