The directions of further improvement of technology of preservation of workings for reuse are defined. Mining-geological, mining-technical and technological initial data on the choice of basic systems of reinforced anchoring of mine workings are determined. The basic principles of development of basic systems of the strengthened anchor fastening of mine workings are defined. New compositions of chemical ampoules for anchoring have been developed jointly with the Composite Products Plant LLC. An efficient drilling tool equipped with diamond-carbide inserts with a significantly longer service life has been developed. The project of Technical conditions "Cutters for drilling of anchor wells equipped with diamond-hard-alloy plates" is developed. Developed "Temporary guide to ensure the stability of precinct workings for their reuse in coal mines of Ukraine", which is a supplement to regulatory documents: SOU 10.1.05411357.10; SOU 10.1.05411357.012; SOU 10.1.0018590.011. Relevant norms and changes have been made to these standards for their consistency. As a result of the work, normative documents and technology of reinforced support and anchor fastening of mine workings were developed, which ensure the stability of mine workings, safety of their conduct and operation, intensive mining operations in mining and tunnel pits and increase of coal production. great socio-economic importance.
