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.
Today, lignite coal-based electricity is a low-cost, efficient
and increasingly clean energy source. BNI Coal brings over 70
years of mining experience to its process, partnering the skills
and talents of its 140 employees
with state-of-the-art equipment
to ensure safe, environmentally sound
production. |
