摘要 The structural de formation of Lu’ an mining area is characterized by a remarkable feature of zoning along E-W direction, in the east limb of Qinshui basin, Shanxi Province, China. The re gional tectonic stress fields and basement tectonics are two fundamental factors to control the cover tectonic framework. This paper uses the finite-element method with a elastic-plastic pIan problem model to simulate the three periods of stress fields resulting from field geological study’ Based on these works, the formation and evolution of tectonic framework of Lu’ an mining area have been discussed.
