| Abstract: | The calculating model is set and the formula of the thickness of the combined beam is deduced by the priciples of structure mechanics. The bolting pattern design is perfected for an oblique trapezoidal sublevel roadway in instable surrounding rocks. The model was applied and verified in the practice. |
