Abstract This paper presents the results obtained from Aiyu mining area of Fuxin coal basin in utilization of such means as apparent resistivity, natural gamma, and gamma-gamma logs for analysing depositional environment with an emphatic summarization of characteristics of logs of geographic environments including alluvial fans, deltas, lakes and rivers. On such a basis and according to the logs of over 100 drilling holes in this area, the Sand-bearing contour map and isopach of coal beds have been drawn, an analysis of which leads to the discovery of the distribution regularity of coal-accumulated zones and coal-rich zones in this area. These data are of universal significance in coal predicting and exploration.
