[0082] Based on the safety data analysis, the miners will undergo personal safety checks to determine whether they have passed the personal safety checks. If yes, the miners will be allowed to work in the mines. If no, the miners will not be allowed to work in the mines.

[0083] Establish ventilation system structure database;

[0084] Based on the historical safety range of important gas concentrations, mine safety monitoring equipment regularly monitors the concentration of important gases in the mine. If any gas concentration does not meet the standard, the safety monitor will instruct the miners to wear self-rescuers and evacuate in an orderly manner;

[0085] Among them, important gas concentrations include gas concentration, oxygen concentration, harmful gas concentration and dust concentration;

[0086] Plan ventilation system troubleshooting plan based on ventilation system structure database;

[0087] Establish a database of power system principles and structures;

[0088] Plan power system maintenance and overhaul plans based on power system principle and structure database;

[0089] The safety monitor monitors the power system fault light in real time to see if it sounds an alarm. If so, the mine electrician will quickly locate the fault location and analyze the cause of the fault according to the power system fault troubleshooting guide, and take measures to repair it. If not, the mine electrician will continue to perform power system maintenance and inspection;

[0090] Establishing medical standards in mines;

[0091] Determine whether the medical level of the mine meets the medical level standards. If not, the miners will not be allowed to go down the mine. If yes, no treatment will be taken;

[0092] Establish a professional medical team and formulate a professional rescue and treatment plan;

[0093] If a major disaster occurs in a mine, the professional medical team will take prompt action according to the professional rescue and treatment plan.

[0094] Reference Figure 2 As shown, the personal safety check specifically includes:

[0095] Check whether the miners' work clothes are damaged, whether the miner's lamp can work normally, whether the safety helmet is qualified, and whether the self-rescuer is normal;

[0096] The safety officer checks whether the miners in each shift have received mine safety knowledge training and passed the mine safety knowledge test.

[0097] Reference Figure 3 As shown in the figure, establishing a ventilation system structure database specifically includes:

[0098] Based on historical data, build ventilation system structure drawings;

[0099] Re-monitor the ventilation system according to the ventilation system structural drawings, compare them with the original ventilation system structural drawings, modify and correct the inconsistencies, and obtain the latest ventilation system structural drawings;

[0100] Based on the latest ventilation system structure drawings, a ventilation system structure database is established.

[0101] The purpose of establishing a ventilation system structure database is to estimate the ventilation conditions of the working environment. As a result, ventilation inspections can be carried out according to the design of the ventilation system structure. As a result, locations with poor ventilation can be discovered in a timely manner, and targeted repairs can be carried out. At the same time, when ventilation anomalies occur, early warnings can be issued to avoid going downhole operations at this time, thereby ensuring the personal safety of operators.

[0102] Reference Figure 4 As shown in the figure, the ventilation system inspection plan includes:

[0103] Based on the type of ventilation method, the ventilator develops a special method for troubleshooting the ventilation system;

[0104] Real-time monitoring of the air velocity in the mine and calculation of the air velocity coefficient H;

[0105] Based on a specially developed method for checking the ventilation system, safety monitors monitor the air velocity at several important ventilation points and use the air velocity coefficient calculation formula to calculate the air velocity coefficient as H. If the H at a ventilation point is judged to be lower than the preset value, the ventilation facilities at that ventilation point are faulty, and the miners are arranged to evacuate in an orderly manner, and the ventilation personnel wear professional equipment for maintenance;

[0106] Develop a regular maintenance and inspection plan for ventilation facilities based on the type of ventilation facilities;

[0107] The air velocity coefficient calculation formula is:

[0108]

[0109] V m T m The air flow rate at the moment, h is the total time period for monitoring the air flow rate, S is the standard air flow rate, and H is the air flow rate coefficient during the monitoring time period.

[0110] The method of troubleshooting is to judge through the air flow rate coefficient. Because when the ventilation is good, the air flow rate will fluctuate within a fixed range. Therefore, the air flow rate coefficient will also fluctuate around a fixed value. Therefore, a judgment basis can be formed based on this to judge the ventilation condition.

[0111] Reference Figure 5 As shown in the figure, establishing the power system principle and structure database specifically includes:

[0112] Based on historical data, the power system principle data is obtained, and the power system principle database is updated according to the existing data to obtain the latest power system principle data;

[0113] Based on historical data, the power system structure data is obtained. According to the power system structure data, the existing power system structure is monitored. The average voltage and resistance calculation formula is used to calculate the average voltage and average resistance of the power facilities. The average voltage and average resistance of the tested power facilities are compared with the original power system structure data. Corrections are made to different places to obtain the latest power system structure data;

[0114] Integrate the latest power system structure data with the latest power system principle data to build a power system principle and structure database;

[0115] The integration steps are as follows:

[0116] Classify the power system structure data according to the types of power system facilities, search for the operating principle of each power facility in the latest power system principle data, integrate the information of each facility in the power system structure data with the operating principle of each facility in the power system principle data, and integrate the lines connecting the power facilities in the power system structure data with the principles of the corresponding lines in the power system principle data;

[0117] The average voltage and resistance are calculated as follows:

[0118]

[0119] Where P i is the rated power of the ith power facility, I i is the current passing through the i-th power equipment, n is the number of power facilities measured, R is the average resistance of the power facilities, and U is the average voltage of the power facilities.

[0120] When working underground, the normal operation of power equipment plays a vital role in safe production, because underground operations cannot be ventilated by natural wind and need to be ventilated with the help of ventilation equipment, which relies on electricity. In addition, workers need to use elevators to go down the well and return to the ground, so power facilities are also needed. Therefore, it is necessary to detect the normal operation of power equipment and formulate corresponding maintenance and repair plans to ensure the normal operation of mining operations.

[0121] Reference Figure 6 As shown in the figure, based on the power system principle and structure database, the power system maintenance and overhaul plan planning specifically includes:

[0130] Based on the update of the power system fault and solution database, the power system fault troubleshooting guide will be updated synchronously in real time.

[0133] Based on historical data, a safety factor is calculated, where the safety factor is equal to the average value of the ratio of the number of people who can live normally after receiving treatment to the number of casualties after all major disasters;

[0134] When the mine safety factor is greater than the preset value, the mine medical level will be recorded as the mine medical level standard.

[0135] Safety accidents in mines are usually unavoidable. Therefore, emergency rescue must be carried out for possible safety accidents. In order to reduce casualties, it is necessary to form a professional rescue and treatment plan to carry out orderly rescue and on-site medical treatment, thereby reducing the number of casualties to a minimum.

[0136] Reference Fig. 9As shown, the professional rescue treatment plan specifically includes:

[0137] After receiving the distress signal, the medical team will take action within the preset time;

[0148] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored, and when the computer-readable program is called, the above-mentioned comprehensive coal mining safety management method based on data analysis is executed.

[0149] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).
