Annotation The absence of a rock mass anchoring in the Donetsk basin using modified concrete reduces the safety of mining operations and does not ensure its long-term strength and stability in the workings of deep coal mines. The object of the research is mining in the system \"rock mass – modified concrete anchor\". The subject of the research is the substantiation of the strength and stability parameters of mining. The purpose of the research is to reveal the regularities of the stress–strain state of the \"rock mass - modified concrete anchor\" system to substantiate the parameters of fixing the rock mass, ensuring the safety of mining operations, increasing stability and reducing the cost of mining deep coal mines. The research methods: mathematical modeling of the stress-strain state of the \"rock mass – anchor – modified concrete\" system. The design scheme of a rock mass presented in the form of a thick shell with anisotropic layers of rocks under the influence of rock pressure and two boundary conditions is considered. A mathematical model of the stress-strain state (VAT) of the \"rock mass-anchor-modified concrete\" system is given. The obtained results of stress studies and a nomogram for the dimensionless quantities determination allowed the authors to substantiate the parameters of the system that ensure its strength and stability in the mine workings of deep coal mines.
Key words Keywords: mining, rock mass, anchor, modified concrete, stresses, displacements, strength, stability, coal mines, support
