Annotation The concept of risk-based technical solutions for the protection of coal mines workings is outlined. The initial data of effective risk management methods are substantiated. A mixed method of risks assessment has been used. The method involves building a matrix of consequences and probabilities by ranking them in the form of tables. The following data have been used as initial data: location, method and parameters of the workings protection, additional measures to manage the state of the rock mass around the workings, cost of certain types of work and material costs, purpose and term operation of the workings. Technical solutions for the protection of underground workings in coal mines to increase labor safety and reduce environmental and financial risks are substantiated. Initial data for effective methods of risks management in the protection of workings in difficult mining and technical conditions have been prepared. It is recommended to use these data as the basis of the new regulatory framework.

Substantiation of calculating the rational parameters of reaction and yielding property of the fastening system in the preparatory mine workings. Methods. The stress-strain state analysis of the "massif -support" system and the normative documents on support calculation of the preparatory mine workings to determine the patterns of link between the fastening system parameters and the main geomechanical factors. Findings. The patterns of geomechanical factors influence on the parameters of reaction and yielding property of the fastening system have been determined, as well as the analytical expressions for their calculation have been obtained. Originality. Correlation-dispersion analysis of the optimization data has revealed a stable exponential relation between the parameters of reaction and the yielding property of support with an index H/R, regardless of the coal-bearing massif structure. Practical implications. Calculation of the deformation-strength characteristic of the fastening system has been developed depending on the mining and geological conditions of maintaining the preparatory mine working.
