<p>Provided is a blow pipe structure for a blast furnace facility configured so as to be capable of suppressing slag adhesion by using a simple structure even if pulverized coal with an unadjusted softening temperature is used. The blow pipe structure is attached to a tuyere (22) in a blast furnace main body (20) that produces pig iron from iron ore. The blow pipe structure injects auxiliary fuel pulverized coal (3) together with hot air (2) and includes a component that melts on to the pulverized coal (3) slag as a result of the hot air (2) and/or combustion heat from the pulverized coal (3). The blow pipe structure has an internal/external double pipe structure having an internal pipe (30b) that continues from a header pipe (41) that supplies the hot air (2) to the vicinity of the tuyere (22) and opens said internal pipe (30b) being provided inside an external pipe (30a) that continues from the header pipe (41) to the tuyere (22). A pulverized coal outlet (31a) for an injection lance (31) into which the pulverized coal (3) is inserted opens to the inside of the internal pipe (30b).</p>
