Abstract

Due to coal wall spalling is also one of the sources of flying gangue, and the displacement of coal wall can qualitatively reflect the degree of wall caving, so this paper use flying gangue in steeply dipping seam as the object of study, based on distinct element method (DEM). By using numerical simulation, the derivative mechanism for flying gangue under the different mining height in steeply dipping seam were systematically studied. The results show that the severity of wall caving has an increasing trend along with mining height increases, and the extent of injury of flying gangue caused by wall caving also has an increasing trend.
