Mining Minister Hernan Martinez said the mine's records indicate it lacked a methane ventilation pipe and gas detection devices
-- basic safety features in all coal mines, where methane gas buildup is common. Lopez said the mine complied with the minimum state requirements set by the state Institute of Geology and Mining. However, the institute said in a news release that experts inspected the mine last month and found it "didn't have gas detection devices, one of the fundamental requirements to guarantee safety in case of an explosion." Jorge Buitrago, general manager of mine owner Carbones San Fernando, was asked whether the mine complied with safety requirements for the monitoring and control of gases. He told The Associated Press that "we complied with the conditions," but refused the elaborate. Most mine explosions are caused by a spark or short-circuit of a motor. At least nine workers were killed at the San Fernando mine last August.
The biggest loss of life at a mine in modern Colombia occurred in 1977 when 85 people died in another mine in Amaga, also in a gas explosion, said Tomas Charris, a Uniandina University researcher. San Fernando is one of 3,000 subterranean mines in Colombia that produce 6 million metric tons of coal a year, said Jorge Martin Molina, an engineer in the mining department at Colombia's National University.
