Research on complex air leakage method to prevent coal

Mar 01, 2019 Spontaneous combustion of coal is one of the major hazards threatening production safety during longwall mining. Mining-induced voids, which provide passages for air leakage, are the key factor triggering spontaneous combustion of coal in longwall goafs. In this study, a comprehensive method, which combined pressure balance, grouting injection, and filling fissures, was proposed to prevent

Development and performance study of a novel

The spontaneous combustion characteristics of coal gangue from the Yangquan mining area were studied through proximate analysis, scanning electron microscope/energy dispersive spectrometer (SEM/EDS), and thermogravimetric analysis. As a result, the coal gangue was found to be prone to spontaneous combustion.
