Abstract

Many N-trending thrust faults have been observed in coal mines of S Illinois and adjacent W Kentucky. Displacement ranges from less than one inch to about 3 m (10 ft). No known ancient tectonic stress field or nontectonic process has been found to have produced these faults; they correspond to the contemporary tectonic stress field in the region-maximum horizontal compression along an axis trending slightly N of E. This compression is thought to account for the preferred orientation of roof failure in underground coal mines, jointing in roof shales, and minor earthquakes in S Illinois.- Authors
