The diversity of coal basins and the late intensive reformation of coal regulations are the remarkable characteristics of Chinese coalfield geology. These largely determine the searching orientation and value of coal exploitation and utilization. The coalfield structure research is one of the basic works and core contents in potential evaluation of national coal resources. In this paper, new thought of carry out coalfield structures research in potential evaluation of coal resources is introduced. The main research contents can be summarized in several aspects, including regional geological setting, structural shape and distribution regularity, tectonic origin and evaluation, structural control of coal. It briefly summarizes the working emphasis of coalfield structures research in different occurrence region of coal in our country.
