Mining Process | BNI Coal
Sixty million years ago, the area where BNI now mines coal was a vast swamp. Plants died, fell into the water and decayed slowly. Eons later, the climate changed and rivers deposited material over the decaying vegetation. The weight of the overlying material pressed the vegetation into lignite seams. Geologists believe it took about 10 feet of decaying vegetation to form one foot of lignite.
