Abstract: Nappe structure is an important and focal point in the field structure geology. The article deals with in detail not only the deformational characteristics of theoverlying thrust sheet, underlying strata and shear slip zone, but also the tectonites of the nappe structure in the adjacent region of Xinglong Mining Area. Applying the new method measuring confined strain, proposed by Ramsay et al., the displacement of the nappe is calculated approximately. On the above basis, a hypothesis is put forward to explain the development of the nappe structure, and an area of 52km² coal-bearing strata underlying the nappe is prognosticated.
