Mine History

Mine Disaster Circumstances

On 12 Sep 1907, two men were killed and forty men were injured twenty of them seriously by an explosion of coal dust in mine No. 10 of the Union Pacific Coal company Thursday afternoon. The explosion was caused by a string of five runaway cars which dashed down the slope on the rails for 200 feet jumped the track and continued several hundred feet farther on the floor of the slope raising a dense cloud of coal dust. At the mouth of entry No. 3 forty miners were waiting to be hauled to the surface. Their lamps ignited the dust cloud and a terrific explosion occurred. Every man was burned and battered and a score were seriously hurt. The mine timbers at the point were destroyed and a number of heavy doors were blown out. The damage is not sufficient to cripple the mine. [1]
