Abstract Guo Erzhuang coalfield is a high-quality anthracite mining area, because of the long-term influence of mining, gradual depletion of resources, mining level gradually to the deep extension for the correctness of the guidance of roadway tunneling layer , so as to reduce the efficiency of enterprise management objectives, through the study of 46 borehole data of deep mine construction, summarize mine deep mining coal seam characteristics, mark feature layer, layer spacing rules, lithology combination characteristics and physical characteristic curves of typical law, by comparison analysis, obtained for guoerzhuang mine coal seam of coal and rock contrast method and the sequential.
