Abstract
A series of experiments in the U.S. Bureau of Mines' Safety Research Coal Mine (SRCM) at the Pittsburgh Research Center evaluated the effects of crosscuts on the travel time of carbon monoxide (CO) along an entry to improve the accuracy of a mine-fire locator program. Three entries, ten single crosscuts, and three double crosscuts were instrumented with CO sensors. One percent CO in nitrogen was released and monitored as it traveled the entries. In addition to the dispersion of CO at the front of the CO wave, CO was entrained from the entry into the crosscuts.
