An absorption-induction convectional dust-controlling/removing air/fog curtain device of a fully-mechanized working face and a method thereof, wherein the device includes an extraction type dust-purifying blower, a sector deflector, a shearer external spraying device and an inter-hydraulic-support spraying device. The shearer external spraying devices are mounted at both sides of a shearer body close to rocking arms of a shearer and the inter-hydraulic-support spraying devices are mounted at two un-advanced hydraulic supports and two hydraulic supports at a leeward side of a front drum of the shearer respectively. Two extraction type dust-purifying blowers symmetrically mounted at the rocking arm close to the body of the shearer are started simultaneously with their air inlets exactly facing front and rear drums of the shearer respectively, and air outlets connected with the sector deflector. With the device and the method, the working environment is improved and safe production of the coal mine is guaranteed.
