Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] The water hazard warning module is used to send out location warning signals according to the spatial characteristics of mine water hazards and feed them back to the dynamic monitoring module to initiate the water hazard emergency treatment plan to achieve the prevention and control of mine water hazards.

[0067] In the above technical scheme, this embodiment realizes the full intelligent and automated management of mine monitoring through the information collection module, dynamic monitoring module, data management module, spatial analysis module, and water hazard warning module, thereby significantly improving the response speed and efficiency of the mine in the face of water hazard threats and building a solid line of defense for mine safety.

[0068] First, the information acquisition module is used to monitor and collect key data of mine water inrush events in real time, including location coordinates, water volume and GIS images, so as to provide initial data for real-time monitoring and analysis of mine water inrush conditions and ensure the acquisition of mine water inrush conditions; then, the dynamic monitoring module is used to extract changes in key mine characteristics within a preset time period based on mine water inrush location information, water inrush volume data and mine GIS images to monitor the mine status, obtain mine abnormal information based on the mine status monitoring results, and analyze changes in key mine characteristics within a preset time period based on the mine abnormal information, such as water inrush frequency, intensity and distribution location information, to achieve accurate monitoring of the mine health status, so as to timely discover abnormal conditions and warn of potential threats; then, the data management module constructs a three-dimensional mine simulation model through historical data, and specifically obtains historical mine water inrush location information, historical water inrush volume and mine GIS images based on the mine rescue management platform to construct a three-dimensional mine simulation model, which is used to screen historical mine water hazard types, identify previous mine water hazard patterns, predict possible disaster types, and enhance preventive measures.

[0069] Furthermore, the spatial analysis module is used to spatially compare the abnormal information with the water hazard type to reveal the spatial distribution pattern of water hazards. By spatially matching the layer data of the mine abnormal information with the mine water hazard type, the spatial characteristics of mine water hazards can be identified and extracted, and the location information of high-risk mine risk areas can be identified and timely prevented and controlled. Finally, the water hazard early warning module sends a location warning signal based on the spatial characteristics of mine water hazards and feeds it back to the dynamic monitoring module to start the water hazard emergency response plan. The early warning signal is generated based on the spatial characteristics, the emergency response plan is activated, the threat can be immediately responded to, emergency evacuation or protection measures can be initiated, and the early control of mine water hazards and the formulation of response plans can be improved.

[0070] As an implementation mode of the present invention, the mine status monitoring mode of the dynamic monitoring module is:

[0071] By formula Calculate the mine coefficient M c ;

[0072] Where M is the total number of water inrush events within the preset time period, and k∈[1,M]; wi k is the kth water inrush frequency, wp k is the kth water inrush intensity, ld k is the kth water inrush location distribution parameter; wi 0 is the standard water inrush frequency, wp 0 is the standard water inrush strength, ld 0 is the standard water inrush location distribution parameter; Δwi is the preset water inrush intensity deviation value, Δwp is the preset water inrush frequency deviation value, Δld is the preset water inrush location distribution parameter deviation value; δ 1 is the first preset weight coefficient, δ 2 is the second preset weight coefficient, δ 3 is the third preset weight coefficient; ε k is the influence coefficient of the kth water inrush position; f is the preset function.

[0073] In the above technical solution, in this embodiment, the dynamic monitoring module is used to realize the safety monitoring and processing of the mine status, specifically through the formula Calculate the mine coefficient M c The mine coefficient here is comprehensively determined based on the water inrush data information obtained through monitoring. During the development of the mine, due to the influence of local geological conditions and environmental factors, the safety conditions for mine settings are generally determined, and as the frequency, intensity and distribution range of water inrush changes, the safety risks of the mine continue to change. The specific safety risks are predicted by the change in the mine coefficient. The size of the mine coefficient can further make a preliminary judgment on the abnormal information of the mine and ensure accurate judgment of the safety risks.

[0074] Among them, the first preset weight coefficient δ 1 The second preset weight coefficient δ is obtained by simulating the importance of the influence of the change of water inrush frequency on the abnormal information of the mine. 2 The third preset weight coefficient δ is obtained by simulating the importance of the influence of the change of water inrush intensity on the abnormal information of the mine; 3 The importance of the influence of the change of the distribution parameters of the water inrush position on the abnormal information of the mine is obtained by simulation calculation; it needs to be further explained that δ 1 , δ 2 , δ 3 , wi 0 、wp 0 ,ld0 All of them are obtained by simulation based on historical data and will not be described in detail here; Δwi, Δwp, and Δld are all selected and set based on empirical data and will not be described in detail here; the kth water inrush position influence coefficient ε k The setting is made based on the different impacts of different water inrush locations on the safety of the entire mine, which will not be elaborated here; the preset function f is an adjustment function set based on historical data to ensure that the adjusted coefficient is within a specific reasonable range.

[0075] As an implementation mode of the present invention, a method of obtaining mine abnormal information according to the mine status monitoring result is:

[0076] The mine coefficient M c and the preset mine coefficient threshold interval [M cA , M cB ] for comparison:

[0077] If M c ∈[M cA , M cB ], it is judged that there is a safety risk in the mine and the current abnormal information of the mine is obtained;

[0078] If M c <M cA , then it is judged that there is no safety risk in the mine;

[0079] If M c >M cB , it is judged that there is a safety problem in the mine and an alarm signal is issued.

[0080] In the above technical solution, the mine status detection result analysis in this embodiment specifically converts the mine coefficient M c and the preset mine coefficient threshold interval [M cA , M cB ] to compare the size; and determine if it falls within the preset threshold range [M cA , M cB ], the mine is judged to have safety risks. This preset threshold interval is the standard result simulated by the machine based on the historical mine-related data. The data falling in this standard interval reflects the result information that needs to be obtained. In addition, if the mine coefficient M c Less than M cA , then it is judged that there is no safety risk in the mine. On the contrary, if M c Greater than M cA , it is judged that a safety problem has occurred in the mine, and an alarm signal notification, emergency power outage and risk avoidance measures are required.

[0081] As an embodiment of the present invention, the detection data of the mine abnormal information includes:

[0082] Mine drainage volume: The mine drainage volume of the mine drainage channel is collected through IoT sensors;

[0083] Mine water inrush volume: The dynamic monitoring module obtains the mine water inrush volume through IoT sensors;

[0084] Mine soil water volume: IoT sensors at the monitoring points of the mine collect the mine soil water volume of the geological soil layer.

[0085] In the above technical scheme, the detection data of mine abnormal information in this embodiment includes mine drainage, mine water inrush, and mine soil layer water volume. The specific data of mine abnormal information can be further refined based on the mine drainage, mine water inrush, and mine soil layer water volume, which is convenient for judging and identifying mine water hazard risks.

[0086] As an embodiment of the present invention, the types of mine water hazards include:

[0087] Roof water damage, bottom plate water damage, borehole water damage, and compound water damage; compound water damage includes a combination of water damage types including roof water damage, bottom plate water damage, and borehole water damage.

[0088] In the above technical solution, the mine water hazard in this embodiment is determined based on the mine drainage channel, including roof water hazard, floor water hazard, borehole water hazard, and composite water hazard.

[0089] As an implementation mode of the present invention, the spatial analysis module performs spatial matching analysis in the following manner:

[0090] Collect the drainage volume layer data set, the water inrush volume layer data set, and the soil layer water volume layer data set of each mine within a preset time period;

[0091] Analyze the curves E of the mine drainage layer data set, the mine water inrush layer data set, and the mine soil layer water volume layer data set that change with time 1 , Curve E 2 , Curve E 3 ;

[0092] Construct the curve E through the same coordinate system 1 , Curve E 2 , Curve E 3 And determine the overlap area S between the two curves respectively 1 , S 2 , S 3 The size is compared with the standard threshold and the corresponding spatial characteristics of mine water hazards are obtained:

[0093] If the overlap area S 1 , S 2 , S 3If all of them are greater than their standard thresholds, it is judged as a complex water hazard risk;

[0094] If the overlap area S 1 , S 2 , S 3 If two of them are greater than their standard thresholds, it is judged as two water damage risks among roof water damage, bottom water damage, and drilling water damage;

[0095] If the overlap area S 1 , S 2 , S 3 If only one of them is greater than the standard threshold, it is judged as a water damage risk among roof water damage, bottom water damage, and drilling water damage;

[0096] If the overlap area S 1 , S 2 , S 3 If all are less than their standard thresholds, it is judged as no risk and other water damage risks.

[0097] In the above technical solution, this embodiment converts the collected layer data through the GIS software platform, and converts the spatial features into digital data. Specifically, firstly, the mine drainage layer data set, the mine water inrush layer data set, and the mine soil layer water volume layer data set within a preset time period are collected; then, the curves E of the mine drainage layer data set, the mine water inrush layer data set, and the mine soil layer water volume layer data set that change with time are analyzed. 1 , Curve E 2 , Curve E 3 ; Finally, construct curve E through the same coordinate system 1 , Curve E 2 , Curve E 3 And determine the overlap area S between the two curves respectively 1 , S 2 , S 3 The size is compared with its standard threshold, and the corresponding mine water hazard spatial characteristics are obtained; by comparing the change trends between different curves, different water hazard spatial information is obtained, and the size of the water hazard spatial characteristics is judged. This judgment result is determined based on the changes in the three characteristics of mine drainage, water inrush and soil water absorption. Generally, the better the channel drainage function, the lower the probability of water inrush and soil water absorption. The corresponding S 1 , S 2 , S 3 They should all be much smaller than the pre-set standard threshold value. Based on the normal change characteristics of this mine, changes that are different from this characteristic should indicate corresponding water hazard risk characteristics.

[0098] Specifically, determine if the overlap area S 1 , S 2, S 3 If the overlap area S is greater than the standard threshold, it is judged as a composite water hazard risk (maximum risk); 1 , S 2 , S 3 If two of them are greater than their standard thresholds, it is judged as two water damage risks among roof water damage, bottom water damage, and drilling water damage (the risk is the second largest); if the overlap area S 1 , S 2 , S 3 If only one of them is greater than the standard threshold, it is judged as a water hazard risk among roof water hazard, bottom plate water hazard, and drilling water hazard (the risk is general); if the overlap area S 1 , S 2 , S 3 If all are less than their standard thresholds, it is judged as no risk and other water damage risks (minimum risk).

[0099] As an embodiment of the present invention, it also includes:

[0100] By formula Calculate and obtain the j-th preset time interval spatial coefficient Sp j ; where θ j is the spatial characteristic influence coefficient of the j-th preset time interval; β a is the overlap area S 1 The preset weight coefficient, β b is the overlap area S 2 The preset weight coefficient, β c is the overlap area S 3 The preset weight coefficient of S 1 ′ is the first standard overlap area, S 2 ' is the second standard overlap area; S 3 ' is the third standard overlap area;

[0101] The j-th preset time interval spatial coefficient Sp j The standard spatial coefficient threshold interval [Sp x , Sp y ] for comparison:

[0102] If Sp j <Sp x , then the current water hazard type risk is judged to be low;

[0103] If Sp j >Sp y , then it is judged that the current water hazard type risk is high;

[0104] If Sp y ≥Sp j ≥Sp x, it is determined that there is a flood at present and a warning signal of the flood location is issued.

[0105] In the above technical solution, the formula Calculate and obtain the j-th preset time interval spatial coefficient Sp j , through the space coefficient Sp j The comprehensive result reflects the change information related to mine water hazards. The data results can further reflect the risk of the current water hazard type. By using the spatial coefficient Sp j The standard spatial coefficient threshold interval [Sp x , Sp y ] for comparison, if it is less than Sp x , then the current water hazard type risk is judged to be low. If it is greater than Sp y , then the current water hazard type risk is judged to be high. If it is within the current standard spatial coefficient threshold range [Sp x , Sp y ], it is determined that there is a water hazard, and it is necessary to issue the specific location information of this type of water hazard and make a signal warning notification.

[0106] Among them, it needs to be explained that S 1 ′、S 2 ′、S 3 ′ are obtained by simulation based on historical data and will not be described in detail here; spatial characteristic influence coefficient θ j The water hazard protection performance of different time intervals is pre-selected and set according to the current mine type and structure, which will not be described in detail here.
