Primary Study on Multilayer Spatial Structure of Overlying Strata in Long-wall Stope

摘要：

Multilayer spatial structure of overlying strata in long-wall stope was studied by two-dimensional similar material simulation and borehole stress meter. As the research showed, there existed a mutual conversion between the beam structure and the arch structure following the advancing of the strop and upper - developing of fracture zone. Before the working face was fully mined, all of the multilayer structures existed in pairs and also under the same large structure. It had been proved through the site measurement of borehole stress meter that the multilayer spatial structure of overlying strata did exist. This thesis also gives a prospect of the application of the academic viewpoint of multioverlying strata spatial structure in mining projects.
