- Abstract
- An improved method of locating an underground mine fire by comparing the pattern of measured combustion product arrival times at detector locations with a real time computer-generated array of simulated patterns. A number of electronic fire detection devices are linked thru telemetry to a control station on the surface. The mine's ventilation is modeled on a digital computer using network analysis software. The time required to locate a fire consists of the time required to model the mines ventilation, generate the arrival time array, scan the array, and to match measured arrival time patterns to the simulated patterns.
