Numerical Simulation of Coal Wall Cutting and Lump Coal Formation in a Fully Mechanized Mining Face [PDF]

International Journal of Coal Science & Technology, 2020
Abstract It is difficult to accurately calculate the lump coal rate in a fully mechanized mining face. Therefore, a numerical simulation of the coal wall cutting process, which revealed the crack expansion, development, evolution in the coal body and the corresponding lump coal formation mechanism, was performed in PFC2D.
