2 major health hazards in the mine are?

• A. Noise and Dust
• B. Heat and Humidity
• C. Gas and Vibration
• D. Lighting and Dust

Answer: (A)

Two primary health hazards in mining are exposure to excessive noise and inhalation of dust. Prolonged loud noise from equipment and blasting can cause permanent hearing loss, tinnitus, and reduced ability to hear warning signals, which raises the risk of accidents and injuries. Dust, especially respirable coal and silica dust, irritates the lungs and over time leads to serious diseases such as coal workers’ pneumoconiosis (black lung), silicosis, chronic bronchitis, and diminished lung function, and it can also cause eye irritation and respiratory infections. These hazards are the most consistently recognized health concerns in many mines, so control efforts concentrate on reducing noise levels and suppressing dust, along with using protective equipment. Other factors like heat and humidity, gas, vibration, and lighting matter for safety, but they are not as universally identified as the top two health risks.
