CT反演技术对309工作面未开采区域进行原位探测。根据探测结果，结合冲击危险性评价模型进行

工作面冲击危险区域的预测，以指导后续卸压防冲工作。此次探测区内煤岩层总体处于中等冲击危

In order to prevent the occurrence of rock burst accidents，based on PASAT-M CT micro⁃

seismic detection system，active CT inversion technology was used to detect the unmined area of 309 work⁃

ing face in Tingnan Coal Mine.According to the detection results，combined with the impact risk assessment

model，the prediction of the impact risk area of the working face is carried out to guide the subsequent pres⁃

sure relief and anti-impact work.The coal strata in the detection area are generally in the middle impact risk

level.The impact risk assessment model considering the seismic wave velocity anomaly coefficient and the

seismic wave velocity gradient coefficient is used to predict，and the results are basically consistent with the

actual situation.The combination of active seismic wave CT inversion technology and impact risk assessment

model can effectively detect the potential impact risk area in the mining area and provide accurate guidance

for the next stage of pressure relief and anti-impact measures.
