In a groundbreaking study published in ‘Meikuang Anquan’ (translated as ‘Mining Safety’), researchers have harnessed seismic channel wave exploration technology to tackle the persistent challenge of accurately detecting geological factors that can lead to disasters in mining operations. The study, led by JIN Mingfang and colleagues, focuses on the Yi’an Mining Industry, specifically examining the geological features at the 11061 working face.
The research addresses a critical concern in the mining sector: the risk of coal seam outbursts and the associated safety hazards. By utilizing seismic channel wave technology, the team was able to analyze the dispersion curves and select the optimal channel wave frequency for their investigation. This method allowed them to perform a short-time Fourier transform on the channel wave train, extracting vital information about the traveling time of the waves in the frequency domain.
“The integration of seismic channel wave technology into our geological assessments represents a significant advancement in our ability to predict and mitigate risks associated with mining operations,” said JIN Mingfang. The researchers successfully created an isoline map of channel wave speed and fitted it with the actual exposed thickness of the coal seam, ultimately producing an isopach map that is crucial for understanding the geological landscape.
In addition to determining the thickness of the coal seam, the study revealed that there were no faults within the working face that could pose a risk, specifically those with a drop greater than half the coal thickness. This insight is invaluable for mining companies, as it allows for more informed decision-making regarding safety measures and production planning.
The practical implications of this research extend beyond mere academic interest. By optimizing local outburst prevention measures based on their findings, the Yi’an Mining Industry reported no abnormal gas emissions during the mining process. Furthermore, the monthly production plan was adjusted according to the thickness changes of the coal seam, ensuring a stable output. This not only enhances safety but also boosts productivity, which is vital in an industry where efficiency directly impacts profitability.
As the construction sector continues to evolve, the integration of advanced detection technologies like seismic channel wave exploration could reshape how companies approach geological assessments and disaster prevention. The ability to accurately map geological features in real-time can lead to safer mining practices and more efficient resource extraction, ultimately benefiting the entire supply chain.
The research, led by JIN Mingfang and his team, underscores the importance of innovation in the mining industry. For more information about their work, you can visit lead_author_affiliation.
