What is the purpose of the "no smoking" policy in coal mines?

The purpose of the "no smoking" policy in coal mines is primarily to prevent fires and explosions that can occur due to the presence of flammable gases commonly found in mining environments, such as methane. Smoking introduces an open flame, which significantly increases the risk of igniting these gases. Coal mines can contain various hazardous materials, and even small ignition sources can lead to catastrophic incidents, including explosions and fires that threaten the safety of miners and can result in severe damage to mining equipment and infrastructure. Therefore, the "no smoking" policy is a crucial safety measure designed to protect miner health and safety by mitigating these risks.
