Abstract: The working face of isolated islands in coal mining is often susceptible to impact-induced dynamic hazards caused by surrounding goaf areas. In this study, CT detection technology (seismic computer-assisted tomography imaging technology) was applied to infer the distribution of abnormal zones within the coal-rock mass of the 5316 isolated island working face at Baodian Coal Mine. By integrating the CT inversion results with microseismic monitoring technology, the impact risk was promptly assessed using relevant microseismic data. The effect of controlling the advancing mining speed was investigated to reduce the pressure on the advanced supports. The study found that the edge support pressure of the goaf, the fault zone, and the connection roadway were the main factors leading to abnormal stress zones in the working face. Excessive pressure on the advanced supports could cause the roof to sink, resulting in increased energy and frequency of microseismic events. By controlling the mining speed of the working face to meet the time required for stress adjustment of the coal seam and roof, it is possible to avoid continuous high-speed mining, ensure sufficient stress adjustment in the working face, and develop corresponding prevention and control measures to ensure mining operations.
