Bellbird Colliery Disaster – 1923 CFMEU Mining Energy

On 1 September 1923 a fire and explosions at Bellbird Colliery in the Hunter Valley caused the deaths of 21 underground coal miners. The cause of the explosions were attributed to the distillation of coal gas within overheated coal heaps. The subsequent ignition of this gas by the fire created the explosions and caused the fire to spread. It was deemed that all of the fire’s
