[0002] Monitoring of coal mine production behavior is crucial to ensuring the ecological and environmental safety of mining areas and avoiding over-exploitation of resources. Illegal mining activities, such as over-capacity production and illegal mining, not only consume national resources, but may also cause geological disasters and environmental pollution, posing a threat to public safety.

[0003] Compliance production monitoring helps improve the economic benefits of coal mines and prevent excessive wear and tear of equipment and reduced production efficiency due to over-intensive production. In addition, by preventing illegal activities such as illegal mining in suspended coal mines, the interests of legitimate coal companies can be protected and market order can be maintained.

[0004] Traditional manual inspection methods are inefficient and usually require a lot of manpower, especially in vast mining areas. Inspectors need to check mining equipment and operating areas one by one, which is a very time-consuming process and difficult to carry out frequently, thus affecting the effect of real-time monitoring. Manual inspections rely on the experience and judgment of individual inspectors, which may produce inconsistent results due to personal subjective judgment and experience differences.

[0005] Coal mining involves many devices and links, and the data sources are diverse, including but not limited to sensor data, production logs, and surveillance videos. How to effectively integrate these heterogeneous data sources is a technical challenge. The illegal mining in closed coal mines is usually highly concealed and difficult to discover and confirm through traditional methods.

[0006] The monitoring system needs to be able to not only process a large amount of data input, but also analyze the data in real time to detect abnormal behavior. This requires the system to have efficient data processing capabilities and a fast response mechanism.

[0007] In order to solve the above challenges, the present invention proposes a method and system for generating dynamic portraits of coal mine production behavior based on production data. The system adopts advanced data processing technology, including machine learning models and complex event processing (CEP) technology, to achieve real-time and accurate monitoring of coal mine production behavior.

[0045] Step 2: Analyze the relationship between coal mine electricity consumption data and personnel positioning monitoring data at different time series to determine the relationship between personnel and electricity consumption.

[0046] The relationship between coal mine electricity consumption data and personnel positioning monitoring data under different time series is analyzed, and the relationship between personnel factors and electricity consumption is obtained. r (t) is expressed as,

[0047]

[0048] Among them, e r is the average power consumption per person, N(τ) is the number of people per time τ, W(τ) is the work intensity function, Δt i It is expressed as the time difference of the i-th worker going up and down the well, and τ is expressed as an integral variable, representing any time point in the time period from t0 to t.

[0049] The work intensity function W(τ) is specifically expressed as:

[0050] W(τ)=H(τ)·(I(τ)·Ψ(τ,N(τ)))·η(τ)·(1+sin(ωτ+φ))

[0051]

[0052] η(τ)=e -λτ

[0053] Among them, H(τ) is the number of working hours in time τ, I(τ) is the labor intensity index, which is obtained based on the physical requirements of the work, Ψ(τ,N) is the dynamic adjustment factor, which takes into account the impact of the number of people on the workload, z is an index that reflects the impact of work distribution on individual workload, η(τ) is an attenuation function that simulates the attenuation of efficiency over time, λ is the attenuation coefficient, ω and φ are the frequency and phase of the sine function, which respectively determine the period and starting point of the change in work intensity.

[0054] Step 3: Analyze the relationship between coal mine electricity consumption data and equipment operation data at different time series to determine the relationship between main mining work and electricity consumption.

[0055] The relationship between coal mine electricity consumption data and equipment operation data under different time series is analyzed, and the relationship between the main mining work of the equipment and the electricity consumption is obtained. s (t) is expressed as,

[0056]

[0057] Among them, α and β represent the power consumption of basic start-stop and additional start-stop, respectively. F(τ) represents the number of basic start-stops of the equipment within time τ. L(τ) represents the operating load of the equipment at time τ. thresh It is expressed as the load threshold. When this threshold is exceeded, additional start and stop are required to protect the equipment. δ(L(τ),L thresh ) is represented as a conditional logic function. When L(τ)>L thresh , δ=1, otherwise δ=0, e s It is represented as the average power consumption of a unit device, and R(τ) is represented as the operating time of the device in time τ.

[0058] Step 4: Analyze the relationship between coal mine electricity consumption data and coal dynamic flow data at different time series to determine the relationship between transportation and electricity consumption.

[0059] According to the dynamic flow of coal in the mine, determine the relationship between transportation and electricity consumption E y (t) is expressed as,

[0062] Step 5: Based on the relationship between personnel and electricity consumption, the relationship between main mining work and electricity consumption, and the relationship between transportation and electricity consumption, a mining intensity evaluation model is constructed.

[0063] The construction of mining intensity evaluation model includes relationship modification and model construction. The relationship modification includes converting the historical total electricity consumption E z (t) minus E s (t) and E y (t), and obtain the difference in power consumption E c (t), denoted as E c (t) = E z (t)-E s (t)-E y (t), the difference in power consumption E c (t) and Er (t) Make the difference and take the absolute value to get the error power consumption E w (t), the error power consumption E w (t) is compared with the minimum allowable error l.

Use E r (t) and E c (t) The reason for the comparison is that the power consumption of personnel is more unstable than that of equipment collection and coal transportation, so E is used. r (t) and E c (t)Comparison can better reflect the error.

[0064] The construction of the mining intensity evaluation model based on the revised electricity consumption relationship is expressed as:

[0065] E j (t) = W1E r (t)+W2E s (t)+W3E y (t)

[0067] Step 6: Determine whether over-intensity production is occurring based on the mining intensity evaluation model, and determine whether illegal mining is occurring based on the relationship between personnel and electricity consumption.

[0068] The new behavior data is arranged in time series and brought into the mining intensity evaluation model to obtain the estimated power consumption of each time series behavior data. The estimated power consumption is compared with the maximum power consumption threshold. If it is less than the maximum power consumption threshold, the data point corresponding to this time series is marked green. If it is greater than the maximum power consumption threshold, the data point corresponding to this time series is marked red. Finally, the behavior data is arranged in time series into a red and green curve through dynamic portraits and input into the terminal.

[0069] Judging whether there is illegal mining based on the relationship between personnel and electricity consumption includes substituting the behavior data when the mining industry is shut down into E r(t), the estimated power consumption of personnel is obtained, and the estimated power consumption of personnel is compared with the minimum power consumption threshold. If it is less than the minimum power consumption threshold, the data point corresponding to this time series is marked green; if it is greater than the minimum power consumption threshold, the data point corresponding to this time series is marked yellow. Finally, the behavior data during the mining shutdown is arranged in time series into a yellow and green curve through dynamic portrait, and input into the terminal.

[0070] Relevant personnel can perform visual operations on the terminal, which is conducive to improving processing efficiency.
