Embodiment Construction
[0067] Figures 1~3 is the best embodiment of the present invention, the following is combined with the appendix Figures 1~3 The present invention will be further described.
[0068] like figure 1 As shown, in the coal mine, there are a working face area 2 and a return airway area 1 and an air inlet roadway area 3 located on both sides of the working face area 2, and the shearer 4 operates in the working face area 2. The linkage dust removal system in the fully mechanized mining face area of the mine is distributed in the return air roadway area 1, the working face area 2 and the air inlet roadway area 3.
[0069] The linkage dust removal system in the fully mechanized mining face area of the mine includes a control host 14 and a number of branch dust suppression units that are uniformly controlled by the control host 14. The branch dust suppression units are located in the return airway area 1, the working face area 2 and the air inlet roadway area 3 There are more th...

The invention discloses a linkage dust-removing system and method used in fully mechanized coal mining face regions of a mine and belongs to the field of dust-removing equipment in an underground coal mine. A plurality of branch dust-removing units are arranged in an underground air return roadway region (1), a working face region (2) and an air inlet roadway region (3) respectively; the linkage dust-removing system is characterized in that each of the air return roadway region (1), the working face region (2) and the air inlet roadway region (3) is provided with at least a dust concentration sensor (13); each dust concentration sensor (13) is connected with any one spraying and dust reduction sub-station (11) in the corresponding region; the spraying and dust reduction sub-stations (11) are connected with a control host computer (14) through a communication bus (7). By adoption of the linkage dust-removing system and method used in the fully mechanized coal mining face regions of the mine, the underground dust concentration can be monitored in real time through the control host computer; the working states of spraying devices can be uniformly controlled by the control host computer according to the dust concentration and the position of a coal mining machine.
Description
technical field [0001] The utility model relates to a method for dedusting the area of a fully mechanized mining face in a mine, belonging to the field of underground dedusting equipment in coal mines. Background technique [0002] Coal mines emit a large amount of dust into the air in all aspects of production, storage, transportation and roadway excavation. Modern fully mechanized mining and fully mechanized excavation equipment has been maturely used in the production process of coal mines, which greatly improves the mining efficiency, but also produces more and more dust. The fully mechanized mining and fully mechanized excavation face is the workplace with the largest amount of dust in coal mines, and its dust production accounts for about 60% of mine dust production. In order to prevent the occurrence of vicious accidents such as coal dust explosion in mines and improve the labor hygiene conditions in mines, the above areas are the focus of mine dust prevention and ...
