| Abstract: |
| Huge Goaf Collapse Caused by the disaster, has seriously affected the safe production in the mine. The general monitoring method can not meet the hugegoaf stability monitoring demand situation. In this paper, the great stability of mined out area has been surveyed by the microseismic monitoring technique. According to the monitoring data of nearly a month, the stability of goaf and the fault activation surrounding the goaf have been analysised. The analysis results got very good application in the goaf stability monitoring in the mine. At the same time in the detector installation process, the installation deviced through the device. The detachably mounted device used in the underground can be repeatedly, greatly reducing the cost of the project. |
