The invention discloses a dust production simulation experiment device for a heading machine cutting head and an experiment method thereof. The device comprises: an organic glass cover, a heading machine simulation device mounting platform, a heading machine simulation device, a compressed air airduct, a ventilation air duct, a pushing rod, and a measuring meter; According to the method, combination of outer computer control and manual regulation is adopted; through adjusting parameters such as stress of coal briquettes or rocks to be cut, cutting angles, cutting positions, and rotation speed during cutting operation, and air-flowing field of the organic glass cover, the real condition of dust production by the heading machine cutting head in the process of coal mining is simulated. The device is simple in structure, reasonable in layout, and is easy to adjust; the dust production condition of the heading machine cutting head with different cutting angles, at different rotation speed, and under different coal bed conditions can be simulated; the method also has functions of timing record and synchronous data processing.
