Research on Roof Movement Monitoring in Working Face by Electromagnetic Radiation |
| |
| Abstract: | The electromagnetic radiation technique is first used for detecting roof movement in working face.This paper describes the principle and method of electromagnetic radiation detection technique and the detected results of roof movement in working face.The results showed that the variation of electromagnetic radiation signal has better correspondence with roof rupture time in working face,the electromagnetic radiation technique can be used for deriving the development of roof movement state in working face and is a new method for detecting roof movement in working face. |
