Where should the effective temperature of the atmosphere be recorded in a mine?

The effective temperature of the atmosphere should be recorded at each coal face where mining operations occur because these locations represent the areas where workers are directly exposed to the mining environment. Recording the temperature at each operational face allows for more accurate monitoring of the specific conditions that miners encounter, which is crucial for ensuring their safety and health.

Mining operations can be highly variable depending on factors such as the depth of the mine, geological formations, and ventilation efficiency. Conditions can change significantly even over short distances within the mine, making generalized readings from a single point, such as the control room or the main entrance, less effective for understanding the actual working environment experienced by miners.

Moreover, temperature monitoring at the coal face can help identify potential risks associated with heat stress or other atmospheric conditions that could influence miners' health and performance. Ultimately, this practice is part of a broader safety management system that aims to minimize risks and ensure optimal working conditions for all personnel involved in mining operations.
