Tunneling working face dust control and fall system

The invention discloses a heading face dust fall control system, and relates to the technical field of dust fall control, the heading face dust fall control system comprises a heading machine main body, a supporting frame is fixedly connected to a machine body of the heading machine main body, a water storage tank containing water is fixedly connected to the top of the supporting frame, and a fixing frame is fixedly connected to the top of a rack, close to a heading cutter head, of the heading machine main body; and an injection dust control device is arranged at the top of the fixed frame. By arranging the dust falling device with two functions, the dust suction mode can be controlled according to whether residual water exists on the inner wall of the water storage tank or not so as to select different dust falling modes, surrounding dust and particulate matter can be effectively gathered together by generating rotating airflow similar to tornado when no water exists, and the dust falling effect is improved.
