The determination of the influence degree of mining-geological and mining-technical factors on the safety of the degassing system

Abstract

This article presents the results of the calculation of methane emission from the development of coal seam and enclosing rocks in the roof on Mine Management “Sukhodolska-Skhidna”. The required degassing efficiency and the degassing method were determined. The degree of influence of mining -technical and mining-geological factors on the safety of the degassing system has established. The determination of the influence degree of mining factors on the safety of the degassing system can be used both at the design stage mine, mining and preparing it, which allow to predict and prevent the formation of an explosive concentration of methane-air mixture.
