Summary
Laser induced fluorescence (LIF) combined with Beluga Whale Optimization-Extreme Learning Machine (BWO-ELM) accurately identifies coal mine water sources. This advanced method overcomes traditional limitations, enhancing safety and efficiency in mining operations.
Area of Science:
- Geosciences
- Environmental Science
- Data Science
Background:
- Traditional coal mine water source identification methods are slow and risk sample pollution.
- Laser induced fluorescence (LIF) offers high sensitivity and real-time detection for water source identification.
- Extreme Learning Machine (ELM) models face challenges with random weight and bias selection.
Purpose of the Study:
- To develop and evaluate an optimized model for rapid and accurate identification of coal mine water sources.
- To address the limitations of traditional methods and standard ELM by integrating advanced optimization algorithms.
- To enhance the safety and efficiency of coal mine operations by preventing water inrush disasters.
Main Methods:
- Laser induced fluorescence (LIF) technology was used to collect spectral data from mixed water samples.
- Data preprocessing involved polynomial smoothing (SG) and spectral multiple scattering correction (MSC).
- Dimensionality reduction was performed using factor analysis (FA) and linear discriminant analysis (LDA).
- Optimized ELM models, including Beluga Whale Optimization-ELM (BWO-ELM) and Particle Swarm Optimization-ELM (PSO-ELM), were constructed and compared with standard ELM and Long Short Term Memory (LSTM).
Main Results:
- The SG-LDA-BWO-ELM model demonstrated superior performance with a fitting coefficient of 0.99990.
- This optimized model achieved a root mean square error of 0.00041 and a mean absolute error of 0.00021.
- The BWO-ELM model exhibited the best convergence and smallest absolute error among all tested models.
Conclusions:
- The integrated LIF and SG-LDA-BWO-ELM approach provides a highly accurate and efficient method for identifying coal mine water sources.
- This technology is crucial for the timely detection of potential water inrush, significantly improving mine safety.
- The findings support the application of advanced AI-driven spectral analysis for proactive disaster prevention in the mining industry.
