Description

Technical Field

[0001] The invention relates to the technical field of mine ventilation prediction, and in particular to a mine ventilation impact prediction system based on data analysis. Background Art

[0002] The main purpose of mine ventilation is to supply enough fresh air underground to meet the oxygen needs of personnel; dilute toxic and harmful gases and dust underground to ensure a safe production environment; regulate the climate underground to create a good working environment, so it is an important factor affecting safe production. The commonly used design steps of mine ventilation network are based on the known tunnel layout, natural ventilation characteristics, and the selection and layout of ventilation facilities based on existing designs or experience. The preliminary design, and then solve the ventilation system and its branch ducts and fans. The air volume, resistance and pressure and other parameters, finally, by making local adjustments to the preliminary design plan, all ventilation parameters meet the requirements, that is, the mine ventilation design is completed.

[0003] The existing mine ventilation prediction system still has shortcomings. When calculating, the existing mine ventilation system often only calculates the ventilation effect under the initial state. However, during use, as the equipment ages and the vents are blocked by dust, the wind pressure, air volume and other parameters of the mine ventilation equipment will be affected, thereby affecting the ventilation effect and causing insufficient mine ventilation.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0005] In the present invention, the ventilation influence coefficients of wind pressure and wind volume are analyzed according to the actual ventilation effect variation range, and then the future wind volume difference or wind pressure difference is predicted according to the analyzed ventilation influence coefficient, so that the system can automatically adapt to different mine tunnel layouts, natural ventilation characteristics and other mining conditions with different ventilation influence coefficients, and at the same time, the ventilation influence coefficients of wind volume or wind pressure can be corrected, so that the prediction ability of the mine ventilation impact prediction system will become more accurate as the use time increases, and the predicted wind volume difference and wind pressure difference can be used to timely predict the possible future insufficient wind volume or wind pressure. Different levels of reminders can be made according to the situation of insufficient air volume or air pressure, so as to remind the administrator to perform maintenance and repair on the equipment before insufficient air volume or air pressure occurs. At the same time, the early warning reminder unit can also detect the real-time air volume or air pressure difference. When insufficient air volume or air pressure occurs, the administrator will be reminded immediately to prevent safety accidents, thereby improving the safety of system use. The problem that it is difficult to make continuous predictions and warnings on the subsequent use of mine ventilation equipment in the existing mine ventilation prediction system, resulting in insufficient ventilation in the mine as the equipment is used for a longer time, and a mine ventilation impact prediction system based on data analysis is proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A mine ventilation impact prediction system based on data analysis, characterized in that it includes a service platform, a mine data acquisition unit, a ventilation impact prediction unit, a ventilation impact review unit, and an early warning control unit. The mine data acquisition unit is used to collect dust density levels outside the mine, wind parameters at the air inlet of the mine ventilation opening, and wind parameters at the air outlet of the mine ventilation opening, wherein the wind parameters include air volume and wind pressure, and the wind pressure boost value and air volume loss value at the mine ventilation opening are calculated by the difference between the wind parameters at the air inlet and the air outlet of the mine ventilation opening. The mine data acquisition unit sends the above data to the service platform;

[0008] The ventilation impact prediction unit can obtain the data sent by the mine data acquisition unit through the service platform, and analyze the data to obtain the wind pressure difference, wind volume difference and dust density level outside the mine at different times, and obtain the influence of the action time of a certain dust density level on the wind pressure difference and wind volume difference through formula analysis, so as to predict the expected change range of the mine ventilation effect under the continuous action of the dust density level, and send the expected change range of the mine ventilation effect to the service platform;

[0009] The ventilation impact review unit can obtain the estimated change range of the mine ventilation effect and the time required to reach the change range through the service platform, and after the time span reaches the estimated time, obtain the actual wind pressure difference and air volume difference at the mine ventilation inlet and the mine ventilation outlet through the mine data acquisition unit, and compare them with the wind pressure difference and air volume difference predicted by the ventilation impact prediction unit, and judge whether the estimated change range of the mine ventilation effect predicted by the ventilation impact prediction unit is accurate through the comparison result;

[0010] The early warning and control unit can obtain the expected change range of the mine ventilation effect and the time required to reach the change range from the service platform, and generate corresponding ventilation danger signals, ventilation reminder signals, and ventilation normal signals according to the expected change range of the mine ventilation effect. The early warning and control unit can also obtain the wind parameter difference at the air inlet and outlet of the mine ventilation port from the service platform, compare the wind difference, and generate corresponding pressurization signals or normal signals according to the wind difference data.

[0011] As a preferred embodiment of the present invention, the process of analyzing data by the ventilation impact prediction unit is as follows:

[0012] The wind pressure difference F0, wind volume difference M0 and dust density level R0 at the starting time point are obtained. When the dust density level R0 changes, the dust density level after each change is recorded as R1, R2... After a period of time T, the wind pressure difference T1 and wind volume difference M1 are obtained again, and the average dust density level R within the period of time T is calculated, R = (R1 + R2... + Rn) / n, and the change range of the mine ventilation effect is calculated according to the formula. The change range of the mine ventilation effect includes the wind pressure change range F and the wind volume change range M. Where K and q are coefficients. The ventilation impact prediction unit predicts the change range of the future mine ventilation effect according to the change range of the above-mentioned mine ventilation effect and the working time t of the ventilation equipment. When predicting the change range of the future mine ventilation effect, the ventilation impact prediction unit obtains the current dust density level Ri, wind pressure difference Fi and wind volume difference Mi, and brings the current dust density level Ri, wind pressure difference Fi and wind volume difference Mi into the above formula, thereby obtaining the expected change range of the future mine ventilation effect after time t. Among them, Fj is the future wind pressure difference of the mine ventilation outlet after time t, Mj is the future wind volume difference of the mine ventilation outlet after time t, and the mine data acquisition unit simultaneously collects the average dust density level within the time t, and sends the expected change range Mj of the mine ventilation effect and the dust density level Ri to the service platform.

[0013] As a preferred embodiment of the present invention, after obtaining the expected change range Mj of the ventilation effect of the mine in the future, the ventilation impact review unit performs timing, obtains the wind pressure difference Ft and the wind volume difference Mt at that time point from the mine data acquisition unit after the time t, and compares the wind pressure difference Ft with the wind pressure difference Fj, and the wind volume difference Mt with the wind volume difference Mj;

[0014] If the difference between the wind pressure difference Ft and the wind pressure difference Fj is less than the preset prediction threshold, a wind pressure prediction accuracy signal is generated; if the difference between the wind pressure difference Ft and the wind pressure difference Fj is greater than or equal to the preset prediction threshold, a wind pressure prediction error signal is generated and sent to the service platform;

[0015] If the difference between the air volume difference Mt and the air volume difference Mj is less than the preset prediction threshold, an air volume prediction accuracy signal is generated; if the difference between the air volume difference Mt and the air volume difference Mj is greater than or equal to the preset prediction threshold, an air volume prediction error signal is generated and sent to the service platform;

[0016] After the service platform receives the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri, the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri are sent to the administrator device. After the administrator device receives the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri, if the average dust density level within time t is the same as the Ri used for prediction, the coefficient K or q is adjusted according to the actual situation. If the average dust density level within time t is different from the Ri used for prediction, the error is caused by the different dust density levels, and the wind pressure prediction error signal or the wind volume prediction error signal is ignored.

[0017] As a preferred embodiment of the present invention, after the early warning and control unit obtains the expected change range of the mine ventilation effect, the wind pressure difference Fj and the air volume difference Mj in the expected change range of the mine ventilation effect are compared with the respective wind pressure threshold or air volume threshold. If the wind pressure difference Fj> the preset wind pressure threshold, a normal wind pressure signal is generated; if the wind pressure difference Fj≤ the preset wind pressure threshold, an insufficient wind pressure signal is generated; if the wind volume difference Mj< the preset wind volume threshold, a normal wind volume signal is generated; if the wind volume difference Mj≥ the preset wind volume threshold, an insufficient wind volume signal is generated;

[0018] When the early warning and control unit generates an insufficient wind pressure signal and an insufficient wind volume signal at the same time, a ventilation danger signal is generated;

[0019] When the early warning and control unit generates only one of the insufficient wind pressure signal or the insufficient wind volume signal, a ventilation reminder signal is generated;

[0020] When the early warning and control unit does not generate an insufficient wind pressure signal and an insufficient air volume signal, it generates a normal ventilation signal. The early warning and control unit sends the ventilation danger signal, the ventilation reminder signal or the normal ventilation signal to the service platform, and the service platform sends the above signal to the administrator device to remind the administrator to perform inspection and maintenance in time.

[0021] As a preferred embodiment of the present invention, the early warning and control unit obtains the current wind pressure difference and wind volume difference from the service platform in real time, and compares them with the respective wind pressure thresholds or wind volume thresholds. If the wind pressure difference is ≤ the wind pressure threshold, it is marked as a wind pressure hazard. If the wind volume difference is ≥ the wind volume threshold, it is marked as a wind volume hazard. When the early warning and control unit identifies any one or both of the wind pressure hazard or the wind volume hazard, a pressurization signal is generated, and the pressurization signal is sent to the mine ventilation equipment and the administrator equipment at the same time. After receiving the pressurization signal, the mine ventilation equipment increases the voltage of the ventilation equipment to increase the air volume and wind pressure in a short time. After receiving the pressurization signal, the administrator equipment promptly reminds the staff and performs maintenance and repair on the ventilation equipment. When the early warning and control unit does not identify the wind pressure hazard or the wind volume hazard, a normal signal is generated without response.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the influence of dust density level on the variation range of mine ventilation effect is calculated through the actual variation range of mine ventilation effect within a period of time, and the ventilation influence coefficients of wind pressure and air volume are analyzed according to the actual variation range of ventilation effect, and then the future wind volume difference or wind pressure difference is predicted according to the analyzed ventilation influence coefficient, so that different ventilation influence coefficients are provided for different mine tunnel layouts, natural ventilation characteristics, etc., so that the system can automatically adapt to different mining conditions and ensure the accuracy of the prediction.

[0024] 2. In the present invention, by comparing the predicted wind pressure difference or wind volume difference with the actually collected wind pressure difference or wind volume difference, the ventilation influence coefficient of the wind volume or wind pressure is corrected, so that the prediction ability of the mine ventilation impact prediction system will become more accurate as the use time increases, thereby realizing the learning evolution of the prediction ability and improving the prediction accuracy.

[0025] 3. In the present invention, different levels of reminders are made in time for possible future insufficient air volume or insufficient air pressure situations through the predicted air volume difference and air pressure difference, thereby reminding the administrator to perform maintenance and repair on the equipment before the insufficient air volume or insufficient air pressure occurs, to prevent the situation of insufficient wind pressure or air volume in the working state and to prevent the impact on work efficiency. At the same time, the early warning reminder unit can also detect the real-time air volume or air pressure difference. When insufficient air volume or air pressure occurs, the administrator is immediately reminded to prevent safety accidents and improve the safety of system use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0029] Embodiment 1:

[0030] See also Figure 1 As shown, a mine ventilation impact prediction system based on data analysis is characterized in that it includes a service platform, a mine data acquisition unit, a ventilation impact prediction unit, a ventilation impact review unit, and an early warning and control unit. The mine data acquisition unit is used to collect the dust density level outside the mine, the wind parameters at the air inlet of the mine ventilation opening, and the wind parameters at the air outlet of the mine ventilation opening, wherein the wind parameters include air volume and wind pressure, and the wind pressure boost value and air volume loss value at the mine ventilation opening are calculated by the difference of the wind parameters at the air inlet and the air outlet of the mine ventilation opening. The mine data acquisition unit sends the above data to the service platform;

[0031] The ventilation impact prediction unit can obtain the data sent by the mine data acquisition unit through the service platform and analyze the data. The process of the ventilation impact prediction unit analyzing the data is as follows:

[0032] The wind pressure difference F0, wind volume difference M0 and dust density level R0 at the starting time point are obtained. When the dust density level R0 changes, the dust density level after each change is recorded as R1, R2... After a period of time T, the wind pressure difference T1 and wind volume difference M1 are obtained again, and the average dust density level R within the period of time T is calculated, R = (R1 + R2... + Rn) / n, and the change range of the mine ventilation effect is calculated according to the formula. The change range of the mine ventilation effect includes the wind pressure change range F and the wind volume change range M. In this formula, only K and q are unknowns. The values ​​of K and q are obtained based on known data, so that different mining areas and different tunnel layouts can have different values ​​of K and q, thereby improving the applicability of the system. K and q are coefficients. The ventilation influence coefficient is calculated based on the above actual situation and used for subsequent predictions. The ventilation influence prediction unit predicts the future range of change of the mine ventilation effect based on the above-mentioned range of change of the mine ventilation effect and the working time t of the ventilation equipment. When predicting the future range of change of the mine ventilation effect, the ventilation influence prediction unit obtains the current dust density level Ri, wind pressure difference Fi and wind volume difference Mi, and substitutes the current dust density level Ri, wind pressure difference Fi and wind volume difference Mi into the above formula to obtain the expected range of change of the future mine ventilation effect after time t. Where Fj is the wind pressure difference of the mine ventilation port after time t, Mj is the wind volume difference of the mine ventilation port after time t, and the mine data acquisition unit simultaneously collects the average dust density level within the time t, and sends the estimated change range Mj and dust density level Ri of the mine ventilation effect to the service platform;

[0033] The ventilation impact review unit can obtain the expected change range of the mine ventilation effect and the time required to reach the change range through the service platform, and after the time span reaches the expected time, obtain the actual wind pressure difference and air volume difference at the mine ventilation inlet and the mine ventilation outlet through the mine data acquisition unit, and compare them with the wind pressure difference and air volume difference predicted by the ventilation impact prediction unit. Through the comparison results, it is judged whether the expected change range of the mine ventilation effect predicted by the ventilation impact prediction unit is accurate. The specific review process of the ventilation impact review unit is as follows: after obtaining the expected change range Mj of the mine ventilation effect in the future, the ventilation impact review unit starts timing, and after time t, obtains the wind pressure difference Ft and air volume difference Mt at that time point from the mine data acquisition unit, and compares the wind pressure difference Ft with the wind pressure difference Fj, and the wind volume difference Mt with the wind volume difference Mj;

[0034] If the difference between the wind pressure difference Ft and the wind pressure difference Fj is less than the preset prediction threshold, a wind pressure prediction accuracy signal is generated; if the difference between the wind pressure difference Ft and the wind pressure difference Fj is greater than or equal to the preset prediction threshold, a wind pressure prediction error signal is generated and sent to the service platform;

[0035] If the difference between the air volume difference Mt and the air volume difference Mj is less than the preset prediction threshold, an air volume prediction accuracy signal is generated; if the difference between the air volume difference Mt and the air volume difference Mj is greater than or equal to the preset prediction threshold, an air volume prediction error signal is generated and sent to the service platform;

[0036] After the service platform receives the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri, it sends the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri to the administrator device. After the administrator device receives the wind pressure prediction error signal or the wind volume prediction error signal and the dust density level Ri, if the average dust density level within time t is the same as the Ri used for prediction, the coefficient K or q is adjusted according to the actual situation. If the average dust density level within time t is different from the Ri used for prediction, the error is caused by the different dust density levels, and the wind pressure prediction error signal or the wind volume prediction error signal is ignored.

[0037] Embodiment 2:

[0038] See also Figure 1 As shown, the early warning and control unit can obtain the expected change range of the mine ventilation effect and the time required to reach the change range from the service platform, and generate corresponding ventilation danger signals, ventilation reminder signals, and ventilation normal signals according to the expected change range of the mine ventilation effect. After the early warning and control unit obtains the expected change range of the mine ventilation effect, the wind pressure difference Fj and the air volume difference Mj in the expected change range of the mine ventilation effect are compared with the respective wind pressure thresholds or air volume thresholds. If the wind pressure difference Fj> the preset wind pressure threshold, a normal wind pressure signal is generated; if the wind pressure difference Fj≤ the preset wind pressure threshold, an insufficient wind pressure signal is generated; if the wind volume difference Mj< the preset wind volume threshold, a normal wind volume signal is generated; if the wind volume difference Mj≥ the preset wind volume threshold, an insufficient wind volume signal is generated;

[0039] When the early warning control unit generates an insufficient wind pressure signal and an insufficient wind volume signal at the same time, a ventilation danger signal is generated;

[0040] When the early warning control unit generates only one of the insufficient wind pressure signal or the insufficient wind volume signal, a ventilation reminder signal is generated;

[0041] When the early warning control unit does not generate insufficient wind pressure signal and insufficient wind volume signal, it generates a normal ventilation signal. The early warning control unit sends the ventilation danger signal, ventilation reminder signal or ventilation normal signal to the service platform, and the service platform sends the above signal to the administrator's device to remind the administrator to perform timely inspection and maintenance.

[0042] The early warning and control unit can also obtain the difference in wind parameters at the air inlet and outlet of the mine ventilation opening from the service platform, compare the wind force difference, and generate a corresponding pressurization signal or normal signal based on the wind force difference data. The specific process is that the early warning and control unit obtains the current wind pressure difference and air volume difference from the service platform in real time, and compares them with their respective wind pressure thresholds or air volume thresholds. If the wind pressure difference is ≤ the wind pressure threshold, it is marked as a wind pressure hazard. If the wind volume difference is ≥ the wind volume threshold, it is marked as an air volume hazard. When the early warning and control unit identifies any one or both of the wind pressure hazard or the air volume hazard, a pressurization signal is generated and sent to the mine ventilation equipment and the administrator equipment at the same time. After receiving the pressurization signal, the mine ventilation equipment increases the voltage of the ventilation equipment to increase the air volume and wind pressure in a short time. After receiving the pressurization signal, the administrator equipment promptly reminds the staff and performs maintenance and repairs on the ventilation equipment. When the early warning and control unit does not identify the wind pressure hazard or the air volume hazard, a normal signal is generated and no response is made.

[0043] In the present invention, the ventilation influence coefficients of wind pressure and air volume are analyzed according to the actual amplitude of change of ventilation effect, and then the future wind volume difference or wind pressure difference is predicted according to the analyzed ventilation influence coefficient, so that the system can automatically adapt to different mine tunnel layouts, natural ventilation characteristics and other mining conditions with different ventilation influence coefficients, and at the same time, the ventilation influence coefficients of air volume or wind pressure can be corrected, so that the prediction ability of the mine ventilation impact prediction system will become more accurate with the increase of usage time, and different levels of reminders can be made in time for the possible future insufficient air volume or insufficient air pressure through the predicted air volume difference and wind pressure difference, so as to remind the administrator to perform maintenance and repair on the equipment before the insufficient air volume or insufficient air pressure occurs, and at the same time, the early warning reminder unit can also detect the real-time air volume or wind pressure difference, and immediately remind the administrator when insufficient air volume or wind pressure occurs, so as to prevent safety accidents and improve the safety of system use.
