Low Profile Drill Rig Automation: FLP1410 by Mine Master in South Africa

The successful commissioning of the FLP1410 drill rig marks a historic milestone for underground mining in South Africa — the country's first automated low-profile single boom drill rig, developed by Mine Master in cooperation with Komatsu Underground Hardrock South Africa and the end user. For operations working in excavations barely taller than a person, this is not a minor upgrade. It is a fundamental shift in what low profile drill rig automation can deliver.

Designed for Ultra-Low Underground Conditions

Low-profile mining environments impose strict constraints on equipment. Limited excavation heights demand machines that are compact enough to maneuver safely, yet capable of delivering consistent drilling performance under pressure.

The FLP1410 was engineered specifically for these conditions. With a minimum machine height of 1.4 meters, it operates efficiently in excavations starting from just 1.6 meters — making it suitable for the demanding environments of chrome, platinum and narrow-reef gold mines across southern Africa, including ultra-deep operations where working conditions are particularly challenging.

The machine builds on the earlier FLP1400-1B model, with targeted improvements driven directly by operator and maintenance team feedback:

• The operator's cab was redesigned for more space and improved ergonomics, with the cooling system upgraded from a fan to a full air-conditioning unit
• Low noise and vibration levels reduce operator fatigue during long shifts
• Access to service components was improved, making daily maintenance faster and more straightforward

Three Levels of Automation: BMS, FGS and ADS

The FLP1410's key differentiator is its automation architecture — a layered system that allows mines to adopt technology progressively, at their own pace.

Basic Monitoring System (BMS) comes as standard on every FLP1410. It continuously collects and records drilling parameters — penetration rate, pressure and deviations for each individual hole — providing the operational data needed for blast planning, rock mass analysis and predictive maintenance.

Feeder Guiding System (FGS) is an optional upgrade that projects the planned drill pattern directly onto the rock face. This allows the operator to position each hole precisely according to the drilling plan, without the need for geological face markings — improving accuracy while keeping the operator in control.

Automatic Drilling System (ADS) takes the process further. Once the machine is correctly positioned, it executes the full drilling cycle autonomously. This is what makes the FLP1410 the only super-low profile machine on the market with fully automated drilling capability.

Safety: The Primary Argument for Automation

Productivity gains from automation are significant. But for the Mine Master and Komatsu development teams, safety was the most important driver.

Underground drillers in low-profile environments face concentrated exposure to rock falls, dust, noise and ergonomic strain. The ADS addresses this directly: once the machine is operating autonomously, the operator can move away from the immediate drilling zone, monitoring the process from a safer distance rather than standing at the face. This near-eliminates several of the most serious risk categories in low-profile drilling and aligns with the broader industry shift toward process supervision over hazardous manual tasks.

Precision That Improves the Entire Production Chain

More precise hole placement produces better excavation geometry across the face, floor, roof and sidewalls. The downstream benefits include improved blasting performance and rock fragmentation, reduced or eliminated need for scaling, easier roof bolting operations, and lower material loss and dilution. Precision at the drilling stage creates a compounding improvement across the full mining cycle.

By controlling drilling parameters tightly and preventing overloads, the ADS also reduces wear on consumable components such as drill bits by up to 30 percent — lowering operating costs and supporting more predictable maintenance planning.

Proven at Dwarsrivier Chrome Mine

The FLP1410 with ADS was successfully deployed at Dwarsrivier Chrome Mine in the Eastern Limb of South Africa, a low-profile room-and-pillar operation within the Assmang Group. Operational experience from this environment validated the machine's performance in demanding geological conditions and demonstrated the practical value of automated drilling for mines facing the dual challenge of ultra-low excavations and the need for consistent, high-quality output.

The FLP1410 has also received formal industry recognition: it was awarded both the Master of Technology of the Copper Belt 2023 and the Lower Silesian Master of Technology 2023 titles by the Supreme Technical Organization — recognition of the engineering achievement behind the machine and its ADS system.
