Fighting underground mine fires with foam producing detergents
Foam plug technique consists of filling mine entry or tunnel tight to back with soap bubbles; these bubbles are moved to fire area by mine ventilating air currents; when foam reaches fire area it tends to quench fire in four ways; it reduces volume of air feeding flames, cools fire area by evaporation, dilutes oxygen, and serves as radiation shield.
