This paper studies the main approaches to optimization principles implementation in innovative technologies for reused mine workings. Based on the experimental data processing and using the correlation analysis methods, the possibility of achieving the correspondence of the deformation-strength characteristics of the fastening structures to the optimal values of loads and displacement, at which the intensity of rock pressure manifestations is minimal, has been proved. A series of multivariate computational experiments with various mining-and-geological and mining-engineering factors have been conducted to determine the characteristics of the fastening structures in the conditions of the Western Donbass coal mines (Ukraine). Based on the comparative analysis of the experiment and analytical calculations, it is possible to represent recommendations for the use of the combined roof-bolting systems in difficult mining-and-geological conditions when maintaining reused extraction coal-mine workings.
