Problems solved by technology
However, due to the close distance between the manned operation area and the location where dust and gas are generated, the concentration of dust and gas in direct contact with the workers on the site is high, which has caused serious harm to human health. Greatly increased, rational layout and improved ventilation have become the key issues to be solved in the current excavation face and tunnel

The device is arranged near the wall surface of a roadway of the driving working face through the traveling mechanisms and is connected with a pressure ventilation barrel, the rotary air blocking plate, the air outlet adjusting plate and the traveling mechanisms are adjusted according to the concentration of dust and gas, an air curtain for controlling dust and gas is adjusted in real time, and dust control and gas control of the working face are achieved; and in addition, the device has the advantages of high adjustment precision, sensitivity in responsiveness and the like.
Description
technical field [0001] The invention relates to the technical field of mine or tunnel ventilation safety, in particular to an intelligent control and self-moving device for dust control air curtains and a dust control method using the device. Background technique [0002] For a long time, dust and gas have been one of the most important factors affecting the safe production of mine driving faces and tunnels. In the mine excavation face and tunnel construction process, high-concentration dust and gas are produced in the coal breaking process, and with the rapid development of construction machinery and equipment, the excavation efficiency has been greatly improved, and the excavation face and tunnel generated The amount of dust and gas seriously threatens the safe production of excavation face and tunnel. [0003] At present, the ventilation system is indispensable during the construction of the excavation face and the tunnel. It is mainly used to provide the necessary oxyge...
