Description

Technical Field

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

[0002] During the process of coal mine mining, the generation of dust is an important and serious potential safety hazard. Coal mine dust not only poses a threat to the health of miners, but long-term exposure to a dusty environment 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 trigger an explosion, causing great safety risks. Therefore, the prevention and control of mine dust is particularly important, and taking effective dust reduction measures is the key to ensuring the safe production of the mine.

[0003] However, existing coal mine dust prevention and control systems usually monitor the dust concentration through manual inspections, regular sampling and testing, etc. However, these traditional methods have disadvantages such as lagging response, low efficiency, and inability to monitor all areas in real time, and cannot achieve comprehensive and real-time control of the dust concentration in the mine. In addition, the layout of dust reduction equipment is often static and cannot be dynamically adjusted according to the actual situation, resulting in unstable dust reduction effects and inability to respond in a timely manner to sudden changes in dust concentration during the coal mine production process. How to monitor and control the dust concentration in a timely manner is an issue that we need to consider currently. Summary of the Invention

[0030] Install the air - flow controller on both sides of the mine roadway. By controlling the air extraction and jetting of the air holes, control the movement direction of the mine dust so that the movement direction of the mine dust points to the filter screen in the dust - settling device;

[0031] Drive the filter screen to move towards the water - spraying device through the roller, and wash the mine dust attached to the filter screen through the water - spraying device to generate mine - dust sewage;

[0032] Obtain the mine - dust sewage generated by the water - spraying device washing the filter screen through the water - receiving tray, and then discharge the mine - dust sewage out of the mine through the drainage pipe;

[0042] Further, the process of obtaining the real - time dust concentration through a dust - concentration sensor, regulating the air - flow controller according to the real - time dust concentration, transporting dust to the dust - settling device through the air - flow controller, generating dust - containing sewage by the dust - settling device according to the dust, and then discharging the dust - containing sewage out of the mine through the dust - exhaust pipe includes:

[0043] The air holes include several aperture sizes, and different aperture sizes correspond to different wind - force levels;

[0044] Set the dust - settling radiation range, dust radiation range, and dust - removal threshold;

[0045] Obtain the real - time dust concentration through a dust - concentration sensor;

[0046] Obtain in real - time the dust coordinates corresponding to the dust - concentration sensors with real - time dust concentrations greater than the dust - removal threshold within the dust - settling radiation range corresponding to the dust - settling device. Determine whether the generated dust has aggregation according to the dust coordinates and their corresponding real - time dust concentrations. If there is aggregation, generate the dust center coordinates according to the dust coordinates and their corresponding real - time dust concentrations. If there is no aggregation, no operation is required; then obtain the air holes within the dust radiation range corresponding to the dust coordinates, and mark the air holes as dust - removal air holes;

[0047] Obtain the geographical location of the dust - settling device, and record the geographical location as the dust - settling coordinates;

[0048] Set the conventional aperture;

[0049] If there are dust center coordinates, take the dust center coordinates as the starting point and the dust - settling coordinates as the ending point to generate a path vector. Then regulate the direction, aperture size, air extraction, and air injection of the dust - removal air holes, and generate a corresponding wind - force vector according to the direction, aperture size, air extraction, and air injection of the dust - removal air holes, so that the wind - force vector of the dust - removal air holes can obtain the path vector through operation;

[0050] If there is no central coordinate of mine dust, the dust removal air hole takes its own geographical location as the starting point and the dust settlement coordinate as the end point to generate a path vector. The diameter of the dust removal air hole is adjusted to the conventional diameter, and then the direction, air extraction and air injection of the dust removal air hole are regulated. According to the direction, diameter, air extraction and air injection of the dust removal air hole, a corresponding wind force vector is generated to make the direction of the wind force vector consistent with that of the path vector;

[0051] The mine dust is attached to the filter screen of the dust settlement device through the wind force vector, and then the filter screen is cleaned by the water spraying device in the dust settlement device to generate mine dust sewage. Finally, the mine dust sewage is received by the water receiving tray in the dust discharge pipeline and discharged out of the mine through the drainage pipeline.

[0052] Further, it is judged whether the generated mine dust has aggregation according to the mine dust coordinate and its corresponding real-time dust concentration. If there is aggregation, the process of generating the central coordinate of the mine dust according to the mine dust coordinate and its corresponding real-time dust concentration is as follows:

[0053] Suppose there are several mine dust coordinates, and the several mine dust coordinates include 、 、 , where n is a positive integer; then the real-time dust concentrations corresponding to the several mine dust coordinates are 、 、 、 , where n is a positive integer, and is the corresponding real-time dust concentration;

If the accumulated result aggregation threshold, the generated mine dust has aggregation, and the central position of the region is obtained and recorded as the central coordinate of the mine dust; otherwise, the generated mine dust has no aggregation.

[0057] Further, the process of obtaining the path vector through the operation of the wind force vector of the dust removal air hole according to the direction, diameter, air extraction and air injection of the dust removal air hole is as follows:

[0058] Generate the direction of the wind force vector according to the direction, air extraction and air injection of the dust removal air hole;

[0059] Generate the modulus length of the wind force vector according to the diameter of the dust removal air hole, that is, generate the modulus length of the wind force vector according to the wind force level of the dust removal air hole;

[0060] Assume that there are several dust removal pores, and the several dust removal pores include , , , , where n is a positive integer; generate the corresponding wind force vectors according to the directions and caliber sizes of the dust removal pores, then generate several wind force vectors, and the several wind force vectors include , , , , where n is a positive integer, and is 's corresponding wind force vector;

[0061] If the path vector is , then the wind force vectors of the dust removal pores can be obtained through operations to get the path vector, that is, .

[0062] Furthermore, the process of obtaining the dust content of the mine dust sewage, generating the corresponding early warning information according to the dust content, and making corresponding processing on the early warning information includes:

[0063] Set a turbidity sensor at the joint of the water receiving tray and the drainage pipe, and obtain the dust content of the mine dust sewage through the turbidity sensor;

[0064] Obtain the geographical location of the turbidity sensor, and generate the monitoring ID of the turbidity sensor according to the geographical location, and the monitoring ID is unique;

[0065] Set up a database and a collection period;

[0066] The turbidity sensor regularly obtains the dust content according to the collection period, obtains the collection time, generates sewage information according to the dust content, collection time and monitoring ID, and submits the sewage information to the database for storage;

[0067] According to the monitoring ID, obtain the corresponding dust content and collection time in the database, and generate the corresponding conventional mine dust range for the monitoring ID according to the dust content and collection time;

[0068] When the database receives the sewage information, obtain the conventional mine dust range corresponding to the monitoring ID in the sewage information. If the dust content in the sewage information is within the conventional mine dust range, no operation is required. If the dust content in the sewage information is outside the conventional mine dust range, generate early warning information according to the monitoring ID in the sewage information, send the early warning information to the user, inform that there is a problem at the turbidity sensor corresponding to the monitoring ID, and let the user make corresponding processing.
