Development of a Mine Shaft Fire and Smoke Protection Prototype System.
3rd WVU Conf on Coal Mine Electrotechnology Morgantown West Virginia, 1976 Aug; :20-1to20-4
This report describes the efforts by the Bureau of Mines and FMC Corp. to define the mine shaft fire and smoke hazard problem, then design, fabricate, and in-mine test prototype hardware for a system that better protects miners and the mine than the shaft-collar rings now commonly used. The resulting mine shaft fire and smoke protection system involves both thermal and smoke detectors, remotely controlled smoke doors at the shaft station, and remotely controlled sprinklers. The system was successfully demonstrated by an actual fire test in the Silver Summit Shaft near Wallace, Idaho, in the spring of 1975. Long-term, in-mine testing of alternative system designs is currently being conducted to show that the system has credibility as a reasonably priced, reliable piece of improved mining health and safety hardware.
