Simulating test on damage regularities of thick sandy soil layer and load distribution on key roof block in shallow coal seams
Through the dynamic simulating model test,the damage caused by mining of thick sandy soil layer upon shallow coal seam is revealed.It is also found that the regularities of dynamic load distribution on the key roof blocks.This discovery will make progress on load transfer mechanism and dynamic roof structure theory.
