Stability control of roadway surrounding rocks under repeated mining: a case study

Scientific Reports
Repeated mining makes the deformation and failure of roadway surrounding rocks more complex than those under single-seam conditions. To address the large deformation and support failure in the 40,111 roadway of the Dafosi Coal Mine, this study combined theoretical calculations and numerical simulations to analyze the evolution of stress, displacement ...
