Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2017, June 20–22, 2017
Paper Number: ISRM-EUROCK-2017-026
... Abstract In this paper, the relationship between the dynamic surface subsidence and overburden separated strata has been studied under the condition of sedimentary coal measure strata. When the underground coal seam is mined, the ground surface subsidence will be caused. The surface subsidence...
