Analysis of Numerical Simulation on Breaking Law of the Composite Key Stratum Affected by Coal Mining

Abstract:

Using FLCA3Dnumerical simulation software, analyzed the different models of different extraction from the composite key layer of breaking the law, respectively to the Composite Key Stratum and non-Composite Key Stratum .The results show that Composite Key Stratum breaking interval was significantly greater than The non-Composite Key Stratum, showing a more obvious composite effect, provides a more adequate proof to the Composite Key Stratum theory.
