Recent advancements in rock burst prevention safety are set to revolutionize mining operations, particularly in coal mines. A groundbreaking study led by Zhenhua Ouyang from the School of Mine Safety at the North China Institute of Science and Technology has introduced a novel classification and weighting evaluation method aimed at enhancing safety measures against rock bursts. Published in ‘Meikuang Anquan’, which translates to ‘Mining Safety’, this research addresses a significant gap in current mining practices—the lack of post-implementation safety evaluations for anti-impact measures.
Rock bursts, sudden and violent failures of rock, pose a serious risk to miners and operations alike. Ouyang’s research categorizes rock bursts into five distinct types: coal type, coal pillar type, roof type, fault type, and comprehensive type. This classification is pivotal, as it considers various factors such as occurrence location, failure form, and load type, providing a comprehensive framework for understanding and mitigating risks.
“Our method not only evaluates the risk before mining begins but also assesses the effectiveness of safety measures after they are put in place,” Ouyang stated. This innovative approach is essential for ensuring ongoing safety in active mining environments, where conditions can change rapidly.
The study proposes a classification weighted evaluation method that integrates multiple safety factors, including surrounding rock conditions, monitoring systems, and management capabilities. The safety factor calculation formula developed in the research allows for a nuanced assessment of anti-impact safety, categorizing it into three levels: safe, basic safe, and unsafe.
By applying this method to the 31119 working face of a mine, Ouyang and his team demonstrated a complete process for evaluating anti-impact safety, validating their findings against real-world incidents of rock bursts. This practical application not only reinforces the reliability of their evaluation method but also highlights its potential commercial implications. Enhanced safety measures could lead to reduced downtime, lower insurance costs, and ultimately, increased productivity for mining companies.
As the construction and mining sectors face growing scrutiny over safety practices, the implications of Ouyang’s research extend beyond coal mining. The classification and weighting evaluation method could be adapted for various construction environments where rock stability is a concern, potentially transforming safety protocols across the industry.
With the mining sector increasingly focused on sustainability and safety, Ouyang’s research represents a critical step forward. The ability to assess and enhance safety measures post-implementation could set new standards for risk management in mining and construction. As Ouyang aptly put it, “Safety is not just a measure; it’s a continuous process that must evolve with our practices.”
