Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of research is the processes of gas evolution that occur on the site of an isolated volume of production. The purpose of the work is to provide scientific and technical assistance in the form of a justification of the criteria (parameters) for evaluating the feasibility of further ventilation of section No. 117 and recommendations on the body thickness of the concrete bridge. Research methods - analytical, theoretical. As a result of the work carried out within the framework of research, the general conclusions were obtained, which give general provisions, changes in the status indicators and explosive gas flows arising from the periodic renewal of ventilation, in accordance with the possible parameters of the ventilation mode during the renewal of ventilation, assessment. the effect of air flow on the possibility of spontaneous combustion of the K5 seam in the ventilation drift of the site No. 117. "Recommendations ....", in which the calculations and the results of the study on the thickness of the body of the bridge made of concrete with S = 15 m2 and recommendations on the thickness of the bridge 0.4 ÷ 0.6 m. The application of this “Conclusion …” and “Recommendations …” in an industrial environment will make it safe to conduct mining operations, which will give a positive economic, environmental and social effect.
