Simulations of goaf surface subsidence via filling control. [PDF]

PLoS One, 2022
Xincheng Gold Mine is taken as an example to investigate the ground subsidence that results from filling. Both numerical simulations and simulation experiments are conducted to simulate the deformation process at the stope roof and bottom from excavation and filling.
