| Abstract: | On the basis of studying the material formula of engineering geological mechanical model experiments,taking the coal mining of the working face in Taiping coalmine,Shandong province as an engineering geological prototype,an engineering geological mechanical model was constructed.The overburden failure and deformation of the bottom soil layer in unconsolidat-ed layers are simulated.The results provided a foundation for determining the height of pillars under water body. |
