Firefighting a Hidden Fire at TTT's Amasra Coalmine with the Innovative One Seven System

24th INTERNATIONAL MINING CONGRESS OF TURKEY -- APR 14-17, 2015 -- Antalya, TURKEYWOS: 000380558200024In a 20 days continuous engagement (07/16 - 08/03 2014) a covered mine fire in the Kalin Damar seam, whose development 5.5 months lagged, could be extinguished by using a One Seven MINING 6000 machine and the Class A foam-concentrate AM. This system is capable to produce compressed air foam, also known as CAF. A total amount of about 91,000 m(3) wet and dry foam was brought into the dammed fire area. The water consumption was 4,200 m(3); the foam-concentrate consumption was 6,320 liters. Finally, it was found that by use of the OS MINING 6000 and the foam-concentrate One Seven AM a fire area could be regained which had to be abandoned using the conventional method (nitrogen inerting). The equipment was recovered and the excavation of the Kalin Damar seam could be continued.UCTEA Chamber Min Enigneers Turke
