[0070] Figure 2 A flow chart of another spray dust reduction control method provided in an embodiment of the present invention is as follows: Figure 2 As shown, the method includes:

[0071] Step 201: Acquire monitoring data in the environment to be sprayed.

[0072] In the embodiment of the present invention, each step is performed by a spray dust reduction control device.

The following machine position area is an area where the unmanned following machine spray function can be executed when unmanned following machine mining is realized in the fully mechanized mining face.

[0076] Specifically, it is determined whether the position of the coal mining machine is within the following machine position area. If so, the following machine spray mode is determined as the target spray mode; if not, it is determined that the target spray mode is not the following machine spray mode.

[0077] It is worth noting that the following machine spray conditions and the following machine position area can be set according to actual needs, and the embodiment of the present invention does not limit this.

[0078] In the embodiment of the present invention, unmanned machine-following mining is to plan the section and time of automatic spray triggering as the position of the coal mining machine changes.

[0080] Specifically, it is determined whether the electromagnetic valve switch signal is on. If so, the auxiliary spray mode is determined as the target spray mode; if not, it is determined that the target spray mode is not the auxiliary spray mode.

[0081] It is worth noting that the auxiliary spray conditions can be set according to actual needs, and the embodiment of the present invention is not limited to this.

[0082] In the embodiment of the present invention, a switch is provided for each solenoid valve to realize the mutual assistance between spraying and other actions, thereby reducing the coal dust generated during the operation of the hydraulic support.

[0084] Specifically, the current dust concentration is compared with the single-machine dust concentration threshold and the grouped dust concentration threshold. If the current dust concentration is less than or equal to the single-click dust concentration threshold, it indicates that the dust concentration in the current working condition is not high and no spray dust reduction is required; if the current dust concentration is greater than the single-machine dust concentration threshold and less than the grouped dust concentration threshold, it indicates that the dust pollution in the current working condition can be solved by single-machine spraying, and the single-machine spray mode is determined as the target spray mode; if the current dust concentration is greater than the grouped dust concentration threshold, it indicates that the dust concentration in the current working condition is high, and the grouped spray mode is determined as the target spray mode.

[0090] Step 204: Based on the underground personnel position information and the underground equipment position information, determine whether the first distance between the hydraulic support and the underground personnel and the second distance between the hydraulic support and the underground equipment are both greater than the preset obstacle avoidance distance threshold. If so, execute step 205; if at least one of them is no, execute step 203.

[0091] In an embodiment of the present invention, the underground personnel position information and the hydraulic support position information (spray position) are calculated by the Euclidean distance calculation formula to generate a first distance between the hydraulic support and the underground personnel; the underground equipment position information and the hydraulic support position information (spray position) are calculated by the Euclidean distance calculation formula to generate a second distance between the hydraulic support and the underground equipment.

[0092] In an embodiment of the present invention, if both the first distance and the second distance are greater than the obstacle avoidance distance threshold, it indicates that the spray will not accidentally spray onto personnel or equipment in the well, the spray distance is safe, and step 205 is continued; if the first distance is less than or equal to the obstacle avoidance distance threshold, or the second distance is less than or equal to the obstacle avoidance distance threshold, it indicates that the spray will spray onto personnel or equipment in the well, the spray distance is unsafe, and step 203 is continued until both the first distance and the second distance are greater than the obstacle avoidance distance threshold.

Specifically, the hydraulic support is controlled to perform spraying according to the spray time and the spray range to achieve action-assisted spray dust reduction.

[0100] In the embodiment of the present invention, the spray parameters corresponding to each target spray mode are spray dust reduction parameters configured by the user through the human-machine interface. The human-machine interface can be in the control room or in the comprehensive mining working face controller device. The configured spray dust reduction parameters are saved on each comprehensive mining working face controller device, which is convenient for real-time adjustment and query by the comprehensive mining working face staff.

[0101] Step 206: During the spray dust reduction process, the state of the target spray pattern is visually displayed.
