6 FAQs about [How to control dust with down-the-hole drilling rig]

How do you control dust at a drill rig?

Controlling dust at the drill rigs can be achieved using a wet suppression system and / or a dry suppression system. The wet suppression system works by introducing water into the bailing air that is send down the drill stem. The water then mixes with the dust and drill chippings at the bottom of the drill hole where the dust is liberated.

How can we reduce dust concentrations around drill rigs?

A number of additional dust suppression interventions were identified. These improvements, listed below, will assist in reducing dust concentrations around the drill rigs: • Increase maintenance frequency on the shroud, sealing ring, suction pipes and filters of the drill rigs.

Will new drill rigs increase dust levels in the open pit?

The introduction of the new drill rigs will contribute to even higher dust levels in or around the open pit. To improve conditions around the drill rigs and reduce the potential exposure of workers it is important to determine the deficiencies of the dust suppression systems currently installed on the drill rigs.

Do drill rigs have dust suppression systems?

Although the drill rigs have dust suppression systems in place, the correct utilisation and maintenance of these systems are often under-utilised due to production pressures. An additional four drill rigs will arrive in the near future to the mine.

Why is dust control important in surface drilling?

Effective dust control in surface drilling is crucial for health and environmental reasons. Methods like wet or dry drilling with dust collection systems are commonly employed. These techniques adapt to the specific operational environment and drilling equipment, ranging from small crawler rigs to large track-mounted drill rigs.

How effective is a dry drill dust control system?

Dry drilling dust control systems can be up to 99% efficient if properly maintained (Cecala et al., 2012). Dust particles and drill chippings escape from the drill collar with the aid of the bailing air and are contained within the drill deck and shroud.
