Through 3D FEM numerical simulation analysis of construction of the adit and main tunnel intersection structure with different intersection angles, this paper draws the conclusions that the smaller the intersection angle, the higher the concentration degree of the surrounding rock stresses and the larger the adit lining stresses.

To extract shaft orbit\'s features invariant to rotation, scaling and translation, the unique strengths of Haar orthogonal matrix type are found, the horizontal and vertical coordinates of shaft orbit are fast proceeded by Haar transform, respectively, and the slopes with different resolutions are obtained at different positions by using the corresponding transform coefficients, and then the multi-resolution angles between the adjacent slope straight line are extracted skillfully and used for the hierarchical recognition, the recognition process accords with the principle of human\'s recognizing things by using hierarchy analysis approach.
