A method by water, adjust the gas excavation face balance, which comprises the following steps: in the slurry warehouse set in semi partition will be divided into a slurry before and after the mud slurry warehouse warehouse two, before and after the mud slurry warehouse warehouse are connected; before the slurry warehouse is full of mud, injecting compressed air in the upper part of sludge storage; the slurry height monitoring liquid level sensor after slurry warehouse in the slurry when the height fluctuation, by adjusting the pump into the mud or mud pump speed will be adjusted to the height of the mud slurry in the preset height; height fluctuation at the same time through the air pressure of the compressed air pressure sensor monitoring after slurry warehouse the intake valve and exhaust valve by adjusting the pressure of compressed air to keep the preset value. Thus, the stability of the excavation face in the whole shield driving process is realized.
