| Black Thunder Coal Mine, surface coal mine Wyoming, located in the Powder River Basin which contains one of the largest deposits of coal in the world. Black Thunder is the second most productive mine in the United States. Black Thunder`s dragline excavator Ursa Major is the biggest working dragline in North America and the third largest ever made.[3][4] It produces enough coal to load up to 20-25 trains per day.[5] Draglines are not used to dig coal but only strip overburden. Black Thunder operates six draglines, not just one. Coal is excavated by power shovels and loaded into haul trucks. |
