Registration Date 13-12-2022 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the study is to ensure the safety of mining operations in the conditions of the mines of LLC «DFEС Dobropillyavugillya», LLC «Krasnolymanske» and State Enterprise "Coal Company Krasnolymanska". The purpose of the work is to develop a set of technical solutions for the safe exploitation of coal seams prone to gas-dynamic phenomena in the mining and geological conditions of the mines of LLC «DFEС Dobropillyavugillya», LLC «Krasnolymanske» and State Enterprise "Coal Company Krasnolymanska". Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, measures have been developed to prevent gas-dynamic phenomena during preparatory excavations and clean-up works, as well as a set of measures to combat gas-dynamic phenomena during preparatory excavations and clean-up works. Participated in the commissions for determining the category of emission hazard and the procedure for working out the mine layers prone to GDР, at the mines of the PE «Management mine Dobropilske» and the PE "Management of the mine "Novodonetske" of the SE «Dobropillyavugillya-mining» for 2021 and 2022; SE "PE Krasnolymanska" for 2021 and 2022; LLC "Krasnolymanske" for 2021 and 2022. The "Passport of the dissection of coal seams l3, l4a and l4(v+c) during the ventilation crosscut of the 1st northern bench of the dumping part of the seam l4 in the mining and geological conditions of LLC "Krasnolymanske" was developed. Forecasts of the emission hazard of coal seams at the place of opening and establishment of zones on the seams safe for coal and gas emissions or extrusion were carried out. Inspection and calibration of PG-2MA devices and inspection of P-1 strength gauge springs were performed. As a result of the application of the developed recommendations, the safety of mining operations is ensured, which is of great socio-economic and ecological importance.
