The invention discloses a multi-pipe down pipe method in a vertical drilling hole. The multi-pipeline down pipe method includes the steps that (A) the vertical drilling hole is constructed in the pipeorifice coordinate position, needing to lower a pipeline, of the middle section of the upper part of a lowering path, and the bottom of the hole communicates with a middle section drift way; (B) allprefabricated pipe sections are sequentially lowered in the drilling hole in a bushing-welding mode, each of the pipelines are lowered and then fixed through support seat devices, and the bottom of apipeline (7) is connected with corresponding horizontal pipelines in a through lane through bends. According to the multi-pipeline down pipe method, working in the hole is not needed, quality of construction is small, the construction period is short, the cost is low, operation safety is guaranteed, and the economic benefit is obvious.
