Abstract: In view of the serious dust pollution in the first-level crushing station of open-pit coal mines, in order to solve the problems of high investment, large energy consumption and poor dust suppression effect in the existing dust control technology, a micro-power induced dust suppression hood for first-level crushing station hopper of open-pit mine was developed based on micro-power induced dust suppression mechanism, and a field application test was conducted. This dust suppression hood has simple structure, is composed of a cover body, a first level dust layer, a second level dust layer and a vibration device. Thus, the air discharged from the hood has passed through two times of dust reduction, the dust concentration has been significantly reduced. It has a good prospect of popularization and application by vigorously improving the production environment.
