Study on dynamic response characteristics of jointed coal mass under impact load
Based on the similarity theorem, the material ratio of similar coal body is determined, and the single-layer thin-plate coal body is prepared by pouring. The multi-layered combined coal mass model with three joint structures is prepared by using the method of dolomite glue cementation. Using the sel...
