Description
technical field [0001] The invention relates to a foam and water mist dual-purpose mining integrated dust suppression device, which is especially suitable for the dust prevention and control of cutting heads of roadheaders, shearer drums, quarries and other dust-producing places. Background technique [0002] During the continuous mining operation in the coal mine, due to the change of the operation process, the change of the property of the cut coal rock and the change of the cutting position will lead to different dust production. [0003] Due to the advantages of low cost, flexible use and convenient maintenance, spray dust suppression technology has been widely used in various dust production points in the mine. However, due to the discrete state between the droplets, it is impossible to achieve a satisfactory dust reduction effect in the case of large dust production such as cutting and drilling. The new foam dust suppression technology utilizes the characteristics of ...
