The Fire Gallery consists of a 90 ft long arched roof tunnel that is coupled to a 6 ft diameter axivane fan by a 20 ft transition section. The cross-sectional area of the tunnel is 84 square feet. The tunnel is equipped with temperature sensors and gas sampling lines. Associated structures include a control room/shop trailer and instrumentation shed.
The Fire Gallery is used to evaluate the fire hazards of mine materials, such as conveyor belting, at various air velocities. Conveyor belt samples up to 50 ft in length are mounted on a typical belt structure and ignited at one end by a gas torch or liquid fuel fire. Flame spread rates and downstream gas compositions and temperatures are measured. The Gallery is also used to train fire brigades and mine rescue teams on the proper procedures to fight conveyor belt fires and liquid fuel fires with water lines and high expansion foam in a confined space.
