Sliding structure characteristics in coal fields of western Shandong

The configurations of the main sliding surfaces and secondary sliding surfaces of the coal field in western Shandong area are analyzed in this paper,as well as their influence on coal seams by sub-sliding surfaces structural pattern in the coal fields is summarized.Based on volcanic activities and tectonic evolution,it is suggested that the tilted fault block,sliding structures in extensional setting should be developed in Cretaceous to Cenozoic age.
