Abstract
Description
Technical Field
[0001] This invention relates to the field of mine ecological monitoring technology, specifically to a mine ecological monitoring method and system based on big data analysis. Background Technology
[0002] Mining processes such as drilling, blasting, ore crushing, and mineral processing generate large amounts of production dust (such as PM10 and PM2.5 with a diameter ≤10μm). When this dust is carried by the wind to the ecological restoration area, it covers the leaves of vegetation, forming a dust film. This not only hinders sunlight and reduces the efficiency of photosynthesis, but also blocks the stomata of the leaves, affecting respiration. In the long run, this can lead to vegetation withering and shedding. At the same time, dust deposited on the soil surface will change the soil pH value, reduce permeability, and affect seed germination and root growth. Its interference with mine ecological restoration is characterized by strong concealment and long duration.
[0003] Traditional detection methods rely heavily on manual sampling and observation, which can only obtain local dust concentrations or vegetation growth status. Furthermore, manual sampling is time-consuming, prone to errors, and fails to capture dynamic changes in dust. Judging dust sources and diffusion trends solely based on experience cannot quantify the dust contribution rate of each operational stage, nor can it accurately predict the extent of dust impact on ecological restoration areas. Moreover, existing systems often only have data monitoring functions and cannot link detection results with restoration measures, making it difficult to optimize mine dust control strategies based on mine ecological feedback analysis. Therefore, this paper proposes a mine ecological detection method based on big data analysis. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a mine ecological monitoring method based on big data analysis, which can link monitoring results with remediation measures, thereby enabling the optimization of mine dust control strategies based on mine ecological feedback analysis.
[0005] The technical solution adopted in this invention is as follows: A mine ecological monitoring method based on big data analysis includes the following steps: S1: Obtain historical basic data for mine ecological monitoring, including historical dust data, historical related ecological data, and historical related operational data; S2: Perform data calibration on the historical dust data, historical associated ecological data, and historical associated operational data from step S1; S3: Based on the historical dust data, historical associated ecological data, and historical associated operational data from step S2, train a big data analysis model to generate a correlation analysis model, which includes: Dust source localization sub-model: The random forest algorithm is adopted, and a multi-classification model is constructed by integrating decision trees. Historical dust data and historical related operation data are used as feature vectors to form a model training sample set. The dust contribution rate of each operation link is output through the decision tree voting mechanism to realize the quantitative localization of dust sources. Dust diffusion prediction sub-model: The computational fluid dynamics numerical simulation method is adopted, and a physical and mathematical coupled model is constructed by combining the atmospheric diffusion equation. Historical dust data and historical related operation data are input, boundary conditions are set, and the dust diffusion trajectory at different time periods is output by solving the continuity equation, momentum equation and diffusion equation. The sub-model for evaluating the restoration effect adopts an LSTM neural network and uses its time series data processing capabilities to build a regression evaluation model. The time series of historical related ecological data is used as training samples to label the restoration effect level for the corresponding time period. S4: Real-time acquisition of dynamic data from mine ecological monitoring. The dynamic data includes real-time dust data, real-time related ecological data, and real-time related operational data. The data is stored as a sub-dataset for each time period, with one day as the preset time period. S5: Summarize the time period subsets in step S4 of the 7-day cycle, generate a dynamic dataset, and then perform data calibration on the dynamic dataset; S6: Input the dynamic dataset from step S5 into the correlation analysis model generated in step S3 to generate phased dust source location results, phased dust diffusion prediction results, and phased remediation effect evaluation datasets within a 7-day period. S7: Based on the phased repair effect evaluation dataset described in step S6, and combined with the historical associated operation data described in step S1, the governance and repair optimization model is trained using LSTM neural network and DQN reinforcement learning algorithm. S8: Input the phased dust source location results, phased dust diffusion prediction results, and phased remediation effect evaluation dataset from step S6 into the governance and remediation optimization model in step S7 to generate an optimization scheme that includes dust suppression equipment parameter adjustments and ecological restoration auxiliary measures.
[0006] Furthermore, the real-time dust data includes TSP, PM2.5, and PM10 concentration data, which are acquired by laser scattering dust sensors. The laser scattering dust sensors are deployed along the perimeter of the mine restoration area and within 50-100m of the dust source, and the distance between two adjacent laser scattering dust sensors does not exceed 200m.
[0007] Furthermore, in steps S2 and S4, historical dust data, historical associated ecological data, historical associated operation data, and real-time dust data, real-time associated ecological data, and real-time associated operation data are all converted into JSON format.
[0008] Furthermore, the dust data calibration in step S2 includes: Calibration samples were acquired monthly using a gravimetric method and compared with concurrent data from a laser scattering dust sensor to calculate the calibration coefficient K. K = gravimetric measurement value / sensor measurement value. When |K~1| is greater than the calibration threshold, the historical dust data is corrected. The corrected data = original sensor data × K.
[0009] Furthermore, in step S4, Real-time dust data is acquired through laser scattering dust sensors deployed in the mine, and the data is transmitted to edge computing nodes in real time. Real-time ecological data is acquired once a day using mobile monitoring equipment, covering all fixed quadrats in the restoration area; Real-time correlated operation data is synchronously acquired through weather stations, equipment control systems, and vehicle positioning systems, and automatically summarized into time-period subsets daily.
[0010] Furthermore, in step S6, The phased dust source location results are output in the form of a pie chart, showing the dust contribution rate of each operation stage, and marking the key sources with a contribution rate of ≥20%. The phased dust diffusion prediction results output the 7-day average diffusion range, marking the affected ecological restoration areas and diffusion direction.
[0011] Furthermore, in step S1, the historical associated ecological data includes vegetation survival rate, leaf chlorophyll content, soil pH value, and soil surface dust deposition amount, and the historical associated operational data includes wind speed, wind direction, daily mining output, dust suppression measures intensity, historical remediation measures data, and historical remediation effect data.

The first generation module is used to train a big data analysis model based on the historical dataset and generate a correlation analysis model. The second data acquisition module is used to acquire dynamic data of mine ecological monitoring in real time. The dynamic data includes real-time dust data, real-time associated ecological data and real-time associated operation data. It is preset that 1 day is a time period and is stored as a time period subset. The summary module is used to summarize the time period subsets in step S4 of the 7-day cycle and generate a dynamic dataset. The second generation module is used to input the dynamic dataset into the correlation analysis model generated in step S3 to generate the phased dust source location results, phased dust diffusion prediction results, and phased remediation effect evaluation dataset within the 7-day period. The third generation module is used to train a governance and repair optimization model based on the phased repair effect evaluation dataset and the historical associated operation data in step S1, using LSTM neural network and DQN reinforcement learning algorithm. The fourth generation module is used to input the phased dust source location results, the phased dust diffusion prediction results, and the phased remediation effect evaluation dataset into the governance and remediation optimization model in step S7, and generate an optimization scheme that includes dust reduction equipment parameter adjustments and ecological restoration auxiliary measures.
[0013] The beneficial effects of this invention are: This invention improves the accuracy and timeliness of mine ecological monitoring, and achieves accurate capture of multi-dimensional data. In addition, to address the shortcomings of traditional monitoring that rely on experience and cannot be quantified, this invention trains a correlation analysis model composed of multiple sub-models based on historical datasets.
