Study on Seismic CT Technology Applied to Coal Mining Face
Abstract：Based on the site measured study results of the seismic CT technology applied to several coal mining faces in the recent years, the paper stated the application principle, method and explanation of the seismic technology applied to coal mining face for different pur- pose detections. The study showed that based on the abnormal rate distribution of the seismic velocity, an evaluation on the mine pressure bumping danger of the coal mining face was conducted and the mine pressure bumping danger area was determined. According to the ab- normal distribution law of the seismic wave velocity band and in combination with the related geological information, a detail exploration of the faults in the coal mining face could be conducted. With the application of the wave velocity zone features in front of coal mining face, the distribution of the pilot support pressure in front of the coal mining face could be divided.
