Bessa

Bessa is a traditional method used in coal mining to control and prevent the expansion of dangerous gas pockets or fires within a mine. It involves creating a defined barrier—often a sealed section—by removing or isolating part of the coal face or entry. This segmentation helps contain hazards, making it safer for miners to work and facilitating targeted geologic or safety interventions. Essentially, Bessa acts as a controlled division within a mine, helping manage risk and improve safety during mining operations.
