Abstract:

The purpose of this study is to determine surface deformation and movement edges due to underground coal mining at the Mong Duong mine. Monitoring data was used to determine angles of draw and angles of boundary. These angles were used to obtain movement and deformation edges caused by other longwall extractions. The comparison between the determined edges and monitored edges showed that there were small differences between both methods. These differences were due to the nonhomogeneously geological conditions of excavating areas. The study demonstrated that angles of draw and angles of boundary can be used to predict deformation and movement edges due to underground mining.
