Description

technical field [0001] The invention belongs to the technical field of mining engineering ventilation and dust removal, and in particular relates to a vortex fog curtain device for a roadheader and a use method thereof. Background technique [0002] my country's coal mine excavation face is seriously damaged by dust. Coal mine comprehensive roadheaders are widely used in coal mine excavation roadways, which generate a lot of dust and noise, and dust will bring health hazards to the workers in the excavation face. Therefore, it is necessary to Dust suppression operation is carried out during machine cutting coal operation. At home and abroad, a lot of research has been done on the problem of dust prevention in fully mechanized excavation in coal mines. At present, in order to reduce the dust concentration in the tunneling face, the conventional spray dust reduction method is usually adopted, that is, the water mist nozzle is installed on the body of the roadheader, the cuttin...
