On the 20th of September 1975 the Kianga #1 Mine exploded killing 13 miners. A fire had developed in the 4 North goaf area and activities were being undertaken to seal off that part of the mine. Just after 5pm a major explosion occurred, killing all 13 men, still working on the seals. The mine was never re-entered and those miners remain entombed in the mine.
