An outburst is a hazardous and complex phenomenon characterized by the sudden and violent release of large amounts of coal and gas within a short period. Such unexpected events can result in catastrophic consequences, including loss of life and considerable economic damage. Coal gas outbursts, driven by rapid and intense energy release, can significantly impact the surrounding environment. In the early stages of these events, coal fracturing and gas discharge are critical determinants of their onset and intensity. This study focuses on the K10 seam of the Tazreh coal mine and utilizes an advanced laboratory apparatus to investigate the energy dynamics involved in such occurrences. The critical energy release was measured at 30.66 mJ/g, with the corresponding threshold pressure for outburst initiation estimated at 0.35 MPa. To evaluate the effect of methane degassing, controlled experiments were conducted on coal samples from the seam using the custom-designed device. The results revealed that reducing the internal gas pressure by 20% through degassing effectively prevented outburst initiation. These findings represent a notable advancement in coal mine safety and offer practical insights for developing proactive risk mitigation strategies in similar high-risk mining environments.
