Deep well mining brings a series of new problems to the design of the pipeline stinger beam of the shaft drainage system, such as the large load on the pipeline beams, the difficulty of type selection and the difficulty of installation. Taking a deep well auxiliary shaft as an example, measures were taken to cancel the temperature force load, and load sharing effect of U-shaped pipe clamp on the escrow beam was studied by combining the theory with practice. Through PROE software, the finite element analysis of the escrow beam was carried out with ANSYS, and the strengthening measures of the beam were creatively integrated into the selection process. The mechanical analysis of the pipeline beam of the deep well drainage system was carried out from three aspects. On the basis of ensuring the safety of the system, the effect of reducing the load of the pipeline beam was achieved, and the specification of the tube pipeline was also reduced.
