| description | The invention relates to the technical field of tunnel engineering experiment research, in particular to an experiment device and method for simulating tunnel stratum gas drainage, the experiment device comprises an experiment box body, a tunnel model, a geological simulation material, a top loading assembly and an extraction assembly, the tunnel model is sleeved with a mounting hole in a sealed mode, the inner side face of the tunnel model is an excavation face, and the top loading assembly is arranged on the excavation face. A differential type digital display displacement meter, a strain type soil pressure box and a gas pressure sensor are arranged on the outer side face of the tunnel model, a differential type digital display displacement meter and a resistance type strain gauge are arranged on an excavation face, and the geological simulation material comprises a stratum simulation material and a coal series simulation material. The top loading assembly comprises a force transfer plate, a counter-force f |
