Mining in the O'Fallon Quadrangle

Mining in this quadrangle began prior to 1874, and continued until 1970. The date of the earliest mining is not known; the 1874 Atlas of St. Clair County shows several mines in this area (including mining within Belleville), some with substantial railroad spurs to the mine tipple. The most recent mine in the O'Fallon quadrangle is the Belle Valley Mine (mine index 929), just east of Belleville. Two of the mines in this area operated for long periods; the St. Ellen Mine (mine index 533) was in operation for 56 years and St. Louis & O'Fallon No. 2 (mine index 416) operated for 49 years.

The Herrin Coal was the only coal mined here, ranging from 5.5 to 7.5 feet thick and 40 to 202 feet deep. A number of mines reported problems with the mine floor "heaving" or "squeezing". These problems typically occur in wet conditions such as this where the bedrock cover above the coal is relatively thin.

Note that a number of mines that are known to have operated in this area could not be located. All of this quadrangle contains minable coal and any area is potentially undermined.
