Which of the following is a major health hazard in mines?

• A. Noise and Dust
• B. Heat and Dust
• C. Noise and Gas
• D. Dust and Water

Answer: (A)

Exposure to noise and inhaled dust are the two most important health risks miners face over time. Hearing loss and tinnitus come from prolonged exposure to loud equipment and blasts, which is why protecting hearing is a central part of mine safety. Dust, especially respirable silica dust, can lodge in the lungs and cause serious diseases like pneumoconiosis (silicosis) and other respiratory problems, reducing lung function and overall health. Because these impacts accumulate with regular exposure, controlling both noise and dust through engineering measures (quieter equipment, ventilation, water sprays), administrative controls (limiting time in noisy or dusty areas), good housekeeping, and appropriate protective gear (hearing protection and respirators) is emphasized in mining safety. While heat, gas, and water hazards exist, noise and dust are the most consistently recognized as major long-term health hazards.
