[0001] The invention relates to the technical field of dust prevention and control, and in particular to an automatic dust adjustment and prevention system for a coal mining process. Background Art

[0002] During coal mining, the generation of dust is an important and serious safety hazard. Coal mine dust not only threatens the health of miners, but long-term exposure to dust can also lead to respiratory diseases and lung diseases, such as pneumoconiosis. In addition, if the dust concentration in the mine reaches a certain level, it may also cause an explosion, posing a huge safety risk. Therefore, the prevention and control of mine dust is particularly important, and taking effective dust reduction measures is the key to ensuring safe production in mines.

[0003] However, the existing coal mine dust control system usually monitors dust concentration through manual inspections, regular sampling and testing. However, these traditional methods have shortcomings such as delayed response, low efficiency, and inability to monitor all areas in real time, and cannot achieve comprehensive and real-time control of dust concentration in mines. In addition, the layout of dust reduction equipment is often static and cannot be dynamically adjusted according to actual conditions, resulting in unstable dust reduction effects and inability to respond to sudden changes in dust concentration during coal mine production in a timely manner.

Finally, the mine dust sewage is received by the water receiving tray in the dust discharge pipe, and then discharged from the mine through the drainage pipe.

[0010] Further, whether the generated mine dust is agglomerated is determined based on the mine dust coordinates and their corresponding real-time dust concentration. If agglomerated, the process of generating the mine dust center coordinates based on the mine dust coordinates and their corresponding real-time dust concentration is as follows: Assume that there are several mine dust coordinates, the several mine dust coordinates include , , , where n is a positive integer; then the real-time dust concentration corresponding to several mine dust coordinates is , , , , where n is a positive integer, and for Corresponding real-time dust concentration; Establish a three-dimensional coordinate system B, and map the coordinates of the mine dust into the three-dimensional coordinate system B; Set aggregation threshold; If there is an area in the three-dimensional coordinate system B, the real-time dust concentration corresponding to the mine dust coordinates in the area is accumulated.

[0011] Furthermore, the corresponding wind force vector is generated according to the direction, caliber, exhaust and jet of the dust removal air hole, so that the wind force vector of the dust removal air hole can be calculated to obtain the path vector in the following process: According to the direction of the dust removal holes, the direction of the wind vector generated by the exhaust and the jet; The modulus length of the wind force vector is generated according to the diameter of the dust removal air hole, that is, the modulus length of the wind force vector is generated according to the wind force level of the dust removal air hole; Assume that there are several dust removal holes, the several dust removal holes include , , , , where n is a positive integer; the corresponding wind force vector is generated according to the direction and diameter of the dust removal air hole, and then several wind force vectors are generated, and the several wind vectors include , , , , where n is a positive integer, and for The corresponding wind force vector; If the path vector is , then the wind force vector of the dust removal hole can be calculated to obtain the path vector even if .

According to the direction, diameter, exhaust and jet of the dust removal hole, the corresponding wind vector is generated to make the direction of the wind vector consistent with that of the path vector. The wind vector causes the mine dust to adhere to the filter screen of the dust reduction device, and then the filter screen is cleaned by the water spraying equipment in the dust reduction device to generate mine dust sewage. Finally, the mine dust sewage is received by the water receiving tray in the dust discharge pipe, and then discharged from the mine through the drainage pipe.
