Study on Earth Pressure of Stope and Sedimentation Transformation Law of a Certain Underground Mine

In order to treat the relationship between stope and goaf of a certain gold mine better,technology of multipoint displacement meter and acoustic emission technique is utilized to monitor displacement transformation law of stope.By analyzing monitoring result,the paper predicts the earth pressure of underground gold mining and displacement sedimentation law.It conducts goaf treatment and secondary orebody recovery safely and effectively,having important guiding significance to safe production of gold stope.
