| Abstract: | Taking the Shengdong mining area shallowly buried seam mining geological condition for example,we study the dynamic mechanism and the rule of soft aquiclude fissure evolution in overlying strata under coal mining conditions.Based on the analysis that water-resisting property of weathering the top of shallowly buried seam with thin bedrock and the rule of overlying strata fissure,we establish the flat mechanics model using the difference method in thin plate theory,application of strain analysis theory,colla... |
