Millstadt Quadrangle

(Redirected from Neponset-Quadrangle)

Mining in the Neponset Quadrangle

Mining took place in the Herrin and Colchester Coals. The Herrin Coal was much shallower and easier to access in both surface and underground mining. However, the coal contained many impurities, including pyrite, bone coal, and clay partings. In one surface mine, the coal was mined in two benches to allow a 2- inch band that was pyrite-rich to be removed by hand shovel. Pyrite was also present as nodules that adhered to the coal. In hand-mining, the nodules were removed at the face and left in the mine. In some mines, horsebacks and clay bands or veins were present in sufficient density to increase the ash content to such a degree that the coal was unsatisfactory. In such mines, the shaft was sometimes deepened to reach the Colchester Coal.
