JNTU B.Tech IV HEALTH AND SAFETY IN MINES Previous Question Paper (February/March - 2022 - R16)

Mining accidents are primarily caused by a combination of human, mechanical, and environmental factors. Key causes include:

• Human Error: Failure to follow standard operating procedures, inadequate training, fatigue, and lack of supervision.
• Mechanical Failure: Malfunction of heavy machinery, failure of hoisting systems, or defects in transport equipment.
• Geological Factors: Unforeseen strata conditions, rock bursts, gas outbursts, or sudden water inrushes.
• Environmental Hazards: Exposure to toxic gases, dust accumulation leading to explosions, and poor ventilation.

To mitigate these risks, the following safety measures must be strictly implemented:

• Strict Compliance: Mandatory adherence to the Mines Act and safety regulations.
• Training and Awareness: Regular safety drills, vocational training, and continuous education on hazard identification.
• Engineering Controls: Implementing advanced roof support systems, automated gas monitoring, and robust ventilation circuits.
• Maintenance: Scheduled preventive maintenance of all mining equipment to prevent mechanical failure.
• PPE Usage: Ensuring all personnel use appropriate Personal Protective Equipment at all times.

Mining accidents often lead to severe environmental degradation, including:

• Water Contamination: Spillage of hazardous chemicals or acid mine drainage resulting from structural failures or uncontrolled flooding.
• Air Pollution: Release of harmful gases and particulate matter due to fires, explosions, or ventilation system failures.
• Land Degradation: Surface subsidence or uncontrolled landslides caused by improper strata management or pillar failure.
• Ecological Disruption: Destruction of local flora and fauna habitats due to the physical impact of accidents and subsequent emergency mitigation efforts.
