| Nature Verified
Abstract Strong mining tremors are a significant trigger of dynamic disasters in deep underground coal mines, especially within the near-field disturbance zone, where they induce intense dynamic disturbances and pronounced cyclic loading-unloading effects. However, the coupled effects of cyclic fatigue and strain rate on the damage and degradation of coal and rock masses remain unclear. This study used seismic-wave forward modelling to identify the strain-rate scale of mining tremor disturbances.

| MDPI
Abstract : Solutions for the maintenance of safety in an isolated working face has not been well achieved; this is attributed to its unique overburden structure and the strong mining-induced stress during the advancement. This paper is devoted to filling this research gap and is based on the case study of LW 10304 in the Xinglongzhuang Coal Mine, in China.
