| VHF | Very High Frequency: A radio-frequency band used for mobile voice and data communications, particularly where terrain and coverage requirements suit its propagation characteristics. |
| VMI | Vendor-Managed Inventory: A supply arrangement in which the supplier monitors and replenishes agreed spare parts or consumables to maintain service levels at the site. |
| VOD | Velocity of Detonation: The speed at which the detonation front travels through an explosive, used to assess product performance and blast-hole conditions. |
| VOD | Ventilation on Demand: Automated control that directs and adjusts underground airflow according to equipment location, personnel presence, contaminants, and operating activity. |
| VR | Virtual Reality: An immersive simulated environment used for operator training, maintenance practice, hazard recognition, design review, and emergency exercises. |
| VRM | Vertical Roller Mill: A grinding machine that compresses material between rotating rollers and a table, often combining drying, grinding, and classification. |
| VSAT | Very Small Aperture Terminal: A compact satellite ground station used to provide voice and data connectivity where terrestrial communications are unavailable or unreliable. |
| VSD | Variable Speed Drive: A general class of drive system that controls motor speed to match process demand, improve control, and reduce energy consumption. |
| VSI | Vertical Shaft Impactor: An impact crusher with a vertical rotor that accelerates material against anvils or a rock bed to produce shaped particles and fine material. |
| W | |
| WLAN | Wireless Local Area Network: A local radio network connecting mobile devices, sensors, machines, and control systems within workshops, plants, pits, or underground areas. |
| WOB | Weight on Bit: The axial force applied to a drill bit, influencing penetration rate, bit wear, vibration, hole quality, and drilling efficiency. |
| X | |
| XR | Extended Reality: The collective term for augmented, virtual, and mixed-reality technologies used in training, visualization, remote assistance, and digital work instructions. |
| XRF | X-Ray Fluorescence: An analytical technique used in laboratory, portable, and online instruments to identify and quantify elements in rock, ore, concentrates, and process streams. |
| Z | |
| ZEV | Zero-Emission Vehicle: A vehicle producing no direct exhaust emissions during operation, including battery-electric and hydrogen fuel-cell equipment. |
