Split Mountain KJ311,is a single-boom,4-wheel drive frame-steered, electro-hydraulic mining development drill rig,for underground hard-rock mines that require very high capacity and reliability.Heavy duty boom complete parallel holding,fast and flexible positioning between holes,with HC109 or HC95LM hydraulic drifter,lowers large boulders in primary drilling,avoiding time consuming and expensive costs within drifting and tunneling of 44 m² sections.Other various options of this mining drill rig make it suitable for a range of tasks, most commonly face drilling, cross-cut drilling and bolt-hole drilling. Well-designed, robust structures and proven components ensure a reliable workplace for both operators and maintenance crews.
This development drill is available in 2 different version:
a,AMSL ≤3000m,
b,3000m ≤AMSL ≤6000m
Both ideal for 5mx5m to 6mx6m or more haulage drifts development drilling,also for exploratory / exploration / surveying drifts drilling.
