Underground drills are the backbone of both development and production mining activities. When drill availability drops, production schedules, safety, and costs are immediately impacted. Effective underground drill maintenance is therefore not optional—it is critical to operational performance.
Preventative maintenance for development drills and production drills focuses on identifying wear and failure points before they result in unplanned downtime. High-impact areas include hydraulic systems, rotation heads, feed frames, electrical controls, and cooling systems. Regular inspections, condition monitoring, and structured service intervals significantly extend component life and reduce catastrophic failures.
A common issue in underground drilling operations is reactive maintenance driven by production pressure. While short-term gains may be achieved, the long-term result is increased breakdown frequency, higher repair costs, and reduced equipment life. A disciplined preventative maintenance program ensures drills operate within design parameters, improving penetration rates and consistency while maintaining safety standards.
At DNM Maintenance Services, our experience across underground development drilling and production drilling equipment allows us to tailor maintenance strategies to site conditions, duty cycles, and manufacturer requirements. The outcome is improved drill availability, predictable maintenance planning, and lower whole-of-life costs.
