Characterization and analysis of discontinuous subsidence ...

While block caving presents an economic means to develop lower grade ore deposits, it often leads to significant ground deformations threatening the safety of overlying mine infrastructure. For guidance on relationships between caving depth and surface subsidence, a comprehensive cave mining database was developed and the database clearly shows caving-induced surface deformations tend to be ...

Discrete and continuous data—ArcMap | Documentation

2020-7-13 · Values that are assigned to the cells of a surface can be represented as either discrete or continuous data. A discrete variable is a number that can be counted. If a variable can assume all values in the interval between two given values, then the variable is continuous. Learn more about how features and surfaces can be represented as either discrete or continuous …

Continuous and discontinuous stability analysis of the ...

The fully continuous methods cannot detect potential instabilities due to movement of individual blocks because they ignore block kinematics. On the other hand, in discontinuous methods (Fig. 5) (DEM, DDA) the resolution of internal stresses inside block elements is less accurate and the possibility of intact rock failure may be overlooked.
