Abstract: 3D numerical analysis model of Lingbao Iron Mine was built by ANSYS software.And the stress concentration area in the level of 80 m was found through calculating the stress distribution of rocks.Combining with the investigation results at the middle section of mined-out area,four acoustic emission monitor spots are optimally arranged,thus providing a base for strengthening the mine rocks and monitoring acoustic emission of ground pressure activities to ensure the safe recovery of mine.
