| Abstract: | Abstract: With the air return way of the 2506 workface in Guantai coalmine as the research object,according to the specific situation of large deformation of rock and difficult to support in the roadway excavation process, the author conducted the similar material simulation test and draw the scope of roadway loose circle. Based on the result of the similar material simulation, we solved the problem of supporting in the soft rock tunnel by reducing the roadway cross-section size and increasing the intensity of support and gave the corresponding suggestions and measures. |
