Mine Life2037
ShapshotApproximately 98 percent of coal from the Center Mine is supplied to the Milton R. Young Station coal-fired power plant located adjacent to the northeast corner of the permit area. There is no rail loadout facility at the Center Mine, nor are there any proximate rail lines that would allow for rail transport of the coal.

Summary:

In the Center Mine the Kinneman Creek (5 feet thick) and Hagel (10 feet thick) beds are the target beds. The Kinneman Creek and Hagel (A and B) coal beds extend throughout much of the central portion of the Oliver county. Fort Union strata is 700 to 1,200 feet thick in this county. Unfortunately, there is little to no subsurface control beyond a depth of about 400 feet in this area.

Processing

Summary:

BNI Energy is a supplier of lignite in North Dakota, produces approximately 4 million tons per year.

After the lignite has been uncovered with the dragline, it must be broken into smaller pieces before it can be hauled to the power plant. This operation is done with bulldozers. The bulldozers at BNI are equipped with a large ripper shank built specifically for breaking coal into pieces small enough to be placed into BNI’s haul trucks.
