A heading face dry dust removing system with a follow-up air duct support comprises a heading machine (1), a reversed loader (2), a movable rack (3), a belt conveyor (4), a dry filter dust remover (5), an extraction type fan (6), a dust suction hood (7), a negative pressure air duct (8), a support rack (9), a suspension slideway (10) and a suspension support (12), wherein the suspension support is fixed at the tail of the belt conveyor, the suspension slideway is suspended on the suspension support, and pulleys (11) matched with the suspension slideway are mounted in the suspension slideway; the negative pressure air duct is divided into a fixed section connected with the dust suction hood and a telescopic section connected with the dry filter dust remover, the fixed section is fixed on the reversed loader through the support rack, and the telescopic section is suspended onto the suspension slideway through the pulleys. The heading face dry dust removing system has the advantages that high dust removing efficiency is coordinated with a heading process, the negative pressure air duct can move along with the heading machine, the work intensity of miners is lowered, the work efficiency of the miners is increased, and time and labor are saved.
