Victor Semenovich Zabyrdyaev: Developed Spaces of Methane-Abundant Coal Mines – A Monograph
This monograph presents a comprehensive study of methane dynamics in coal mines, focusing on the developed (goaf) areas of methane-abundant seams. It examines methane content in primary emission sources and the gas emission patterns of goaf spaces during coal extraction. The work investigates the interaction between liquid droplets and dust particles, as well as the petrographic characteristics of fossil coals and their influence on methane and dust release, along with the explosibility of methane-dust-air mixtures.
The book provides factual data on coal seam methane content in the solid mass and within the influence zone of the longwall face, as well as methane emission into mine workings and degasification boreholes. Gas-dynamic processes in extraction areas are analyzed, including frictional sparking as an ignition source for methane. The author proposes methods and means to prevent methane and coal dust ignition from frictional sparking during coal cutting by shearers.
Intended for scientific and engineering professionals, as well as students, postgraduates, and doctoral candidates in mining-related fields.
