Abstract: ISS has been developed for years. However, the application of ISS has never came to the truth in supper coal face. This paper studied the application of ISS in one supper coal face in northern Shaanxi. The geologic condition of ISS is very well for getting interesting records. For finding out the layout of the faults already exposed in roadway, all patches were set on for mostly receiving the channel waves. By analyzing the records of ISS and the CT image we got, the layout of the interest faults has been explained, which coincides basically with the actual situation later exposed in roadway. The explanation of the faults provides important information for the coal face production. The successful application of ISS in supper coal face provides technical support for exploration in panel.
