Description
Summary:Abstract As the depth of coal mining continues to increase, mining disturbances can easily induce rock bursts, which seriously restricts the safe and efficient production of the mine. Therefore, we took a combination of theoretical analysis, mathematical modeling, and field application and selected the 1102 working face of Yadian Coal Mine as the research background. The primary control factors contributing to rock bursts were analyzed, and a mathematical model for rock burst risk evaluation was developed. The research results show that geological objective factors and human subjective factors were the primary factors of rock bursts, with respective weights of 0.75 and 0.25. Burst tendency and coal pillar width played the most significant influence on rock burst occurrences. A multi-level risk evaluation model for rock bursts in coal mines was developed based on fuzzy mathematics theory. The 1102 working face has weak rock burst hazards, consistent with on-site conditions, so verifying the precision and dependability of the evaluation model and offering a crucial theoretical foundation for the evaluation and prevention of rock bursts in coal mines.
