Based on the existing research results, Fluent software is applied to analyze the flow field in the pressure pipeline by theoretical calculation and numerical simulation, and the numerical simulation study of the three-dimensional horizontal pipeline is carried out to obtain the velocity and pressure distribution clouds of the flow field at the bend of the pressure pipeline, and analyze the foam under different inlet pressure, gas-liquid ratio, and the changes of various elements such as flow velocity, and obtain the commonly used polymer dust-reducing foam in the actual process The law of the change of pressure loss in the pipeline by air-liquid ratio and inlet pressure size is explored, and the influencing factors and mechanisms affecting the structural performance of the roadheader foam transport pipeline are discussed, the initially designed pipeline is optimized, and the simulated outlet pressure results are simulated for foam injection. The results show that polymer dust reduction foam in the process of pipeline transportation, the pressure loss rate before the optimization is about 90%, and the pressure loss rate after optimization is 60%; the optimized pipeline foam will be more stable and concentrated at the exit speed; when the air-liquid ratio is certain, the pressure loss rate will increase gradually with the increase of inlet pressure; when the pressure is certain, the pressure loss rate will gradually decrease with the increase of air-liquid ratio; the pipeline foam will be more stable and concentrated with the increase of outlet pressure. The pressure loss rate gradually decreases with the increase of gas-liquid ratio at a certain pressure; the pressure loss of the hand-shaped four-way in the pipeline is significantly better than that of the tapering tube-type positive four-way; the foam spraying simulation is carried out at the lowest outlet pressure, and the effective range of foam can reach 4m, which meets the requirement of "wrapped" coverage of foam spraying. The optimized pipe structure provides a reliable basis for the optimized design and scientific research of applying polymer dust-reducing foam in the roadhear pipeline.
