Dangers of Underground Mining
This video discusses the dangers associated with underground mining, including exposure to high levels of noise and lack of natural light and ventilation.
00:00:02 This video discusses the dangers associated with underground mining, including exposure to high levels of noise and lack of natural light and ventilation. It also highlights the risks involved in the mining process and the importance of design considerations and proper spatial distribution to mitigate geomechanical risks.
🔍 Miners in underground mining are exposed to dangerous levels of noise, lack of natural light, and insufficient ventilation.
⚠️ Accidents can occur at any stage of the mining process, and there are design risks that need to be considered when selecting the extraction method.
🛠️ Proper infrastructure, including ventilation, fortification, and spatial distribution, is crucial for minimizing critical risks in underground mining.
00:01:07 The risks of underground mining operations are influenced by factors such as human error, equipment mechanization, and environmental conditions. These risks include fires caused by welding, coal dust, and electrical installations. A special protection device called an auto-rescuer can be used to escape in case of fire.
🔍 The key factors that contribute to mining accidents are human factors, mechanization of equipment, and environmental conditions.
🔥 Three risks associated with underground mining are fires caused by welding, wooden fortification, and coal dust.
🛡️ The use of a special protective device called an auto rescuer is recommended in case of fire inside the mine.
00:02:11 This video discusses the dangers associated with underground mining, including the risks of using contaminated self-rescuers, rock explosions, traffic accidents, and handling explosives.
🔍 The use of auto rescuers is restricted to environments with a minimum of 19.5% oxygen and without toxic gases or vapors.
💥 Rock explosions in underground mining occur due to rock instability and poor blasting design.
🚗 Only diesel vehicles should be used in underground mines to avoid common risks such as collisions, overturning, and sliding equipment.
💣 Explosives should be handled with caution and under specific regulations.
00:03:17 This video discusses the risks associated with underground mining operations, including storage and transportation of explosives, drilling and blasting, and personnel safety measures.
🔒 The risks associated with underground mining operations include handling explosives, storage, transportation, and blast preparation.
⚠️ Safety measures such as using safety harnesses and safety nets are necessary for personnel working in underground mines.
💨 Compressed air is essential for powering pneumatic equipment in underground mines.
00:04:24 The video discusses risks associated with underground mining, including high-speed particle projection, noise, water accumulation, traumatic injuries, professional deafness, and dehydration.
⚠️ The dangers associated with underground mining include projectile particles, high noise levels, and potential water accumulation leading to soil instability.
💥 Physical risks in underground mining range from minor injuries to fatal accidents, with trauma being the main concern.
🔇 Professional deafness can result from various mining activities such as drilling, blasting, and crushing.
🌡️ Dehydration is a risk in underground mining due to increasing air temperature and higher barometric pressure at depth.
00:05:29 This video discusses the health risks associated with underground mining, including the risk of silicosis, lung fibrosis, rheumatoid arthritis, kidney disease, and lung cancer. It also mentions the dangers of gases like methane and carbon monoxide. Overall, underground mining is a high-risk occupation that is trying to reduce risks through technology and training.
🔍 There are hygienic risks associated with underground mining, such as the presence of crystalline silica in rocks, which can lead to silicosis and other health issues.
💣 Explosive gases like methane and carbon dioxide pose a serious risk in underground mining, requiring constant monitoring.
⚒️ Although efforts are being made to reduce risks in underground mining through new technologies and worker training, it remains a dangerous occupation.
