The article gives outcome of the analysis of geological conditions in coal mining. The study includes such characteristics of coal seams as thickness, dip, depth of occurrence and coal and gas outburst hazard. A special emphasis is placed on characteristics that affect safety of development drivage and coal-face operation. In this context, it has been found that 87.5 % of coal seams in Russia are combustion-hazardous or prone and very prone to spontaneous combustion. Furthermore, enclosing rocks are characterized based on roof controllability, roof stability and floor strength.  The analysis has covered all coal seams under mining with underground method in Russia. Besides, aimed to forecast geological conditions for coal mining up to 2030, the data on promising unalloted workable coal seams are analyzed. Considering closure of operating mines and commissioning of new mines, geological conditions are forecasted for coal mining over the period up to 2030.
