The invention discloses a space three-dimensional dust control and removal method for dust produced during bracket moving of a fully mechanized mining face. Different dust-proof measures are conductedon the upper, middle and lower spaces of the fully mechanized mining face, an air curtain machine or different kinds of nozzles is/are utilized to form a gas-water double-curtain closed space and a single fog filed closed space, a sensor sends a signal to a central processing system, thus fully-automatic spraying dust-reduction in the bracket moving process of column descending, bracket advancing, column ascending and the like is conducted, and the high-concentration dust is concentrated in the closed space to be treated in a concentrated mode, or the high-concentration dust is blocked outside the closed space; by utilizing closed dust-isolation and spraying dust-reduction modes, a wireless transmission system is adopted, a remote control device is utilized to send a radio signal, a signal processor receives the signal and transmits the signal to the controller, thus the controller can adjust the air volume of the air curtain machine, the spraying range of the nozzles and the water passing pressure, the dust reduction efficiency in the bracket moving process is improved to 95% or above, coal dust explosion accidents are avoided, and the operation environment of workers is also greatly improved.
