| Abstract: | The influences of the supports' working resistance due to the overlying strata breaking and falling during the coal caving had be analyzed based on the whole wave acoustic emission rock mechanics experiment,the physical simulation experiment of the supports' working resistance in 6.2 m high coal mining,and the numerical simulation with the FLAC3D software.The statistical analysis of simulative supports' working resistance had be arranged and the adaptive supporting intensity or supports' resistance was given.The study provided the scientific foundations for confirming the parameters of the supports' resistance and safety exploitation with 6.2m high height seam mining in Yangchangwan coal mine. |
| Keywords: | high seam mining simulation experiment FLAC3D numerical simulation rock pressure rules shield working resistance |
