Analysis of the fire propagation in a sublevel coal mine
Rights accessOpen Access
A fire has been analyzed in a real underground coal mine, using a sublevel method, duringan entire year. The study was focused on the collapsed area, reproducing a real mixture formed bycoal, waste, and air gap. The analysis was done by means of an experimental analysis, a computationalfuid dynamic model (CFD), and simulations using a mine ventilation software. Three scenarios weredetermined and studied regarding their influence on the evolution of the fire: (a) development ofthe fire without taking any action, (b) sealing offthe affected areas, and (c) sealing and reducing theventilation in the affected area and surrounding drifts. The study revealed the behavior of the fire ina real mine and the effectiveness of the main fire-fighting measures over time, verifying that none ofthe measures taken could eliminate the fire-induced in the collapsed area.
