Trenton Quadrangle


Mining in the Trenton Quadrangle

Mining in this quadrangle began prior to 1879, and continued until 1996. The most recent mine is Monterey Mine No. 2 (mine index 0974), extending west into the Lebanon quadrangle from Breese quadrangle. Southern No. 9 (mine index 0084) operated the longest, almost 40 years.

The Herrin Coal was the only coal mined here, ranging from 4.0 to 8.3 feet thick and 180 to 345 feet deep. Where geologic problems were reported, the full range of problems was encountered. The roof contained slips, and faults with 5 to 10 feet of displacement were noted. Clay dikes and rolls were present, and in some areas partings were present in the seam.
