In mining, what is the practice of mixing fresh air to control methane levels called?

The practice of mixing fresh air to control methane levels in mining is referred to as diluting. This process is crucial in maintaining safe working conditions, as methane is a highly flammable gas that can create dangerous situations if accumulated in high concentrations. By introducing fresh air into the mine, the concentration of methane is reduced, thereby minimizing the risk of explosions or other hazardous occurrences.

Effective dilution strategies often involve ventilating the mine with air that helps to flush out accumulated gases, ensuring that workers are in a safer environment while performing their tasks. This method is widely employed in mining operations to mitigate the dangers posed by methane and other harmful gases.
