Charge rigs and spray rigs are among the most safety-critical machines operating underground. Their performance directly affects ground control, blast integrity, and the safety of personnel working in active headings.
Maintenance of underground charge rigs requires strict attention to hydraulic systems, delivery accuracy, control systems, and structural integrity. Any deviation in performance can compromise blast outcomes and introduce significant risk. Regular calibration, hose inspections, and system testing are essential to ensure compliance and operational reliability.
Similarly, underground spray rigs play a vital role in ground support and environmental control. Failures in pumps, nozzles, or boom systems can delay development activities and compromise ground stability. Preventative maintenance ensures consistent application rates, reliable operation, and reduced exposure to unplanned shutdowns.
Due to the specialised nature of this equipment, maintenance must be carried out by technicians with a clear understanding of underground operating conditions and safety requirements. Generic maintenance approaches often fall short in managing the risks associated with these machines.
