Abstract. In 2023, three previously isolated exogenous fires happened in the mines of Ukraine in the conditions of the Pokrovske and Pershotravenske mines that had to be extinguished and then written off. These fires occurred as a result of explosions of methane-air mixture in the workings of excavation sites of the southern wall 11, block 10, and of the northern "bis" wall 9, block 10 in the Pokrovske mine and in the workings of the wall 586 in the Yuvileyna mine of the PJSC “DTEK Pavlogradvugillia”.

The purpose of this work was to analyze the regulatory requirements for the safe value of carbon monoxide concentration in the isolated space of the accident site for writing off a fire.

Method. To achieve this purpose, it was necessary to perform an analysis of determining and to establish dynamics of changes in the background concentrations of carbon monoxide and hydrogen, as indicator gases, in the isolated space of the accident site of the southern wall 11, block 10 in the Pokrovske mine, and in the workings of wall 586 in the Yuvileyna mine.

Discussion. Since the background values of indicator gases in the places of the future fire are not always determined, it is probably necessary to somewhat increase the number of locations for assessing background values of CO and H₂ concentrations. Hence, there is a need to evaluate concentrations of tracer gases near explosion-proof bulkhead and at excavation sites, and also near other locations, for example, at the ends of degassing wells and in gas pipelines. Besides, it is necessary to specify more exactly the locations and order of mine measurements, as well as the method of calculating the safe parameters of indicator gases necessary for a possible write-off of a mine fire.

Practical significance. Based on the analysis of the conducted experiments and the results of fire extinguishing, recommendations were developed to clarify the regulatory documents by adding a clause to the new regulatory document in the following wording: "When extinguishing a fire by a combined method by way of flooding the accident (excavation) area and at a decrease in the temperature of water and air from the isolated site, the period for reducing values of concentration of indicator gases to safe limits can be shortened, for example, by 2–3 times, upon agreement with the SPMRS and availability of recommendations of a scientific professional institution."

Keywords: indicator gases, carbon monoxide, coal mine, explosion, fire, write-off, accident site, explosion-proof bulkheads.
