Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of research is degassing of the coal massif in the conditions of the mine Dobropilska «Mine management Dobropilske», "DFEK Dobropillyavugillya" LLC. The purpose of the work is to provide scientific and technical assistance in the development of technical solutions for the safe development of the 10th northern lava of the m51 slope of the mine Dobropilska. Research methods – generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the technical documentation for the development of the 10 northern lava of the slope of the m51b of the mine "Dobropilska" "Mine management Dobropilske" LLC "DFEK Dobropillyavugillya" was analyzed. The calculation of the expected methane release within the excavation site, air flow for ventilation of the excavation site is performed. "Measures to control the degassing system of the excavation site during fires in the mine workings" have been developed. The project of degassing of the 10th northern lava of the m51 slope in the mine Dobropilska of the «Mine management Dobropilske» of DFEK Dobropillyavugillya LLC has been developed. Developed "Recommendations for gas safety of the excavation section 10 of the northern lava of the slope of the formation m51v when using a reverse ventilation scheme, type 1-M", "Recommendations for safety during operation of the gas suction unit ВМЦГ-7M excavation section 51 of the northern lava of the shaft, “Recommendations for ensuring dust and gas safety of coal excavation works in the 10 northern lava of the m51v formation slope when releasing fresh air into the fresh stream of air coming to its ventilation m51v and the slope of the formation m51v", "Recommendations for ensuring gas and endogenous fire safety in the workings for the duration of the dismantling of equipment of the mine "Dobropilska". Results of implementation of developments - application of the developed recommendations allowed to provide gas safety. Product Description popup.authors popup.nrat_date 2021-06-22 Close
