Mined lignite coal from Luminant’s Turlington Mine – normally used to fuel Big Brown Power Plant in Freestone County – is now generating educational opportunities at the Perot Museum of Nature and Science in Dallas. Donated lignite samples will be used in the museum’s geology presentations and in geology kits for teachers to use in their classrooms.
“Lignite is interesting to study because it was formed millions of years ago by the decomposition of plant material in swamp-like environments,” said Melinda Parker, Luminant senior geologist. “As the plant material was buried and compacted, increasing temperatures and pressures led to the formation of coal. Lignite is the lowest-ranking coal and is a reliable source of power generation.”
The Perot Museum also shared Luminant’s lignite samples with the Houston Museum of Natural Science, the Fort Worth Museum of Science and History, and the Nature Exchange at the Dallas Zoo.
Luminant’s goal is to quickly return mined land to productivity and achieve all regulatory reclamation obligations. For more than 40 years, Luminant has set the standard in mined land reclamation, restoring nearly 80,000 acres, planting more than 38 million trees and creating or enhancing more than 5,100 acres of wetlands, ponds and stream channels.
Luminant Lignite 101:
- Luminant’s mining team produces lignite from the Calvert Bluff Formation – a major lignite-producing formation in the Texas Gulf Coast region.
- Our mining team recently achieved the lowest injury rate in the nation among the largest mining companies, according to a review of the 2015 MSHA Recordable Injury Rates. Watch the latest Eye on Luminant video to find out how the team is digging into the record books.
- Luminant mining is the largest mining company in Texas and the ninth largest in the United States.
