Development of a complex methodology for forecasting the stability of coal-bearing rocks, taking into account the whole existing array of geological-geophysical and mining-technological information, which can and should be used in the design of new coal producing enterprises and existing mines. Methodology. The proposed complex method for forecasting the stability of coal-bearing rocks involves the sequential implementation of three interrelated stages: 1) calculation of the compressive and tensile strength of rocks (layered and in massive) for 20-meter roof interval and 10-meter subsoil coal seams. 2) selection and quantitative assessment of weakened cavernous-fractured zones in well logs according to standard and acoustic logging and geological documentation; 3) characteristics of the active roof of coal seams in terms of stability, load-bearing properties and controllability.enforecasting stability methodcoal-bearing rocksgeologic cross- sectiontensile strengthArticle
