Essay

The presented dissertation is a completed scientific-research work in which the urgent scientific-technical problem of optimizing the interaction modes between the coal-bearing mass of weakly metamorphosed rocks and innovative fastening structures, including combined roof-bolting systems, has been solved in order to maintain reusable extraction workings; optimization solutions are based on disclosing the interaction process mechanism occurring in conjunction with the determined patterns of the impact of the deformation-strength characteristics of fastening structures on minimizing the parameters of rock pressure manifestations; this makes it possible to form a unified strategy for their resource-saving improvement to increase the reliability and safety of mining the coal seams in complex mining-geological conditions. Based on the performed analysis of existing research and practical experience in the application of innovative technologies for maintaining mine workings, the relevance and novelty of the approach to optimizing the interaction modes between the rock mass and fastening systems in the conditions of weakly metamorphosed rocks under the direct influence of stope operations in reused extraction workings have been substantiated. The research solves a set of interrelated tasks, structured into a single concept of combined approaches to controlling the parameters of rock pressure manifestations and taking into account the peculiarities of using innovative fastening systems to maintain reused extraction workings in a weakly metamorphosed coal-bearing mass; the following algorithm for realizing the research purpose is used. The formulated principles of coordinating the operating modes of fastening elements and their general adaptation to the patterns of rock pressure manifestations have substantiated the need to study the interaction process within the framework of “force – displacement” (reflected by the concept of “deformation-strength characteristic”) with criteria for minimizing the rock pressure and the maximum possible approximation to the condition of equal strength elements that constitute the fastening structure. The mechanism of deformation and interaction of armored and rock thrust structures in the roof and frame support with the surrounding mass has been disclosed, which is the basis for determining the quantitative patterns of the interrelation between geomechanical factors and deformation-strength characteristics of fastening structures, including combined roof-bolting systems.
