What is the effect of poor mine ventilation?

Poor mine ventilation significantly increases the risk of accidents and health issues for miners. Proper ventilation is essential in underground mining operations as it ensures the supply of fresh air and the effective removal of hazardous gases, dust, and heat. When ventilation is inadequate, the concentration of respirable dust, toxic gases like carbon monoxide or hydrogen sulfide, and heat can rise to dangerous levels, leading to respiratory issues, heat-related illnesses, or even fatal accidents.

Additionally, poor air quality due to insufficient airflow can impair a miner's ability to work safely and efficiently, resulting in decreased productivity and greater chances of operational mishaps. Thus, the implications of inadequate ventilation extend not only to the immediate health risks for individuals but also to the overall safety and operational effectiveness of mining activities.
