Which component is essential in a dust control program in a coal mine?

• A. Only using fluorescent lighting.
• B. Wearing sunglasses at all times.
• C. Housekeeping, alongside water sprays, ventilation, dust extraction, and training.
• D. Ignoring dust data.

Answer: (C)

Dust control in a coal mine relies on a combination of measures that target dust at the source, prevent its spread, and ensure workers follow safe practices. Housekeeping is essential because it directly removes accumulated dust from surfaces, equipment, and floors. When dust isn’t allowed to build up, there’s less material that can become airborne later through movement, vibration, or air currents. Regular cleaning reduces re-entrainment of settled dust and helps keep other control methods working effectively. This approach works best when housekeeping is used alongside other controls like water sprays, ventilation, and dust extraction, plus training. Water sprays suppress dust where it’s generated, ventilation dilutes and removes airborne dust from the work area, and dust extraction captures dust at source. Training ensures workers know how to use these controls properly and understand when cleaning is needed to prevent dust buildup. Together, these elements create a layered, proactive program that reduces exposure more reliably than any single measure. Choosing options that focus on lighting or eyewear doesn’t address dust, and ignoring dust data prevents knowing whether controls are working or need adjustment.
