the limestone formations of the Eastern and Midwestern U.S. can be much higher than the overburden stress. Horizontal stresses in limestone formations have been measured in limestone mines [7] and in many of the area's coal mines [12]. Research has shown that the horizontal stress may be explained by the effect of plate tectonics [7, 13].
