Simulation analysis of pressure relief effect of upward mining in the lower protective layer (group) of deep extra-thick coal seam
Abstract In this paper, an examination of the upward mining of multi-protected layers through simulation is conducted in a mine in Dongsheng Coal Field, China, as an example. FLAC3D numerical simulation software was used to calculate the mining scheme of the lower protected layer (group) and analyze...
