without their bodies being retrieved. In 1986 a second disaster occurred, as an underground explosion, which took the lives of 12 miners. The bodies of all those persons were retrieved. In Moura on 7 August 1994 a third major mining accident occurred with an explosion at Moura No. 2 Mine. A second explosion at the mine approximately a day and a half later saw rescue attempts abandoned, and the mine was sealed, with the bodies of the 11 miners unretrieved. In the 1996 Gretley coal mine disaster, near Newcastle, four men were killed when their mining machine broke into the flooded workings of an old coalmine, abandoned over 80 years earlier. Four miners were killed in a windblast incident at the Northparkes mine outside the New South Wales town of Parkes in 1999. Belgium On March 4, 1887, 120 miners died in a coal mine in La Boule, Borinage due to a methane explosion. On the morning of August 8, 1956, a fire in the mine Bois du Cazier in Marcinelle caused 262 victims, with only 12 survivors. A mining cart on an elevator cage hit an oil pipe and electricity lines, with the resulting fire trapping the miners. Most of the victims were immigrants (136 Italians, 8 Poles, 6 Greeks, 5 Germans, 5 Frenchmen, 3 Hungarians, 1 Englishman, 1 Dutchman, 1 Russian and 1 Ukrainian.) Bosnia and Herzegovina On September 4, 2014, after a 3.5 Richter earthquake hit Zenica caused rock burst in coal mine "Raspotočje", 34 miners remained trapped inside the mine. It was later reported that 5 miners were killed in the accident. Canada On 17 May 2006, four people died due to asphyxiation in an accident at the decommissioned Sullivan Mine. On 18 September 1992, at the height of a labour dispute at the Giant Mine near Yellowknife, an explosion resulting from a bomb planted by striking worker "Roger Warren", killed nine men riding through a transport tunnel. Coal mining accidents in the province of Nova Scotia spanning 65 years referred to collectively as the Springhill mining disasters, which claimed in total at least 138 lives of men and boys due to coal dust explosions. The Westray Mine disaster in 1992 claimed the lives of 26 miners in a methane/coal dust explosion at a recently opened mining operation. Both of these mines were subsequently permanently closed in the wake of these events. On May 20, 1980,
