Abstract
Abstract
| Knowledge of initial ground pressures or in-situ stresses and mechanical properties and geological conditions is of great importance in drivage and maintenance of a mine roadway. Field measurements of the in-situ stresses and the geological and mechanical properties have been carried out. However, these methods are really impractical in using in underground mines. Alternatively, back analysis method using measured displacements during drivage of roadway can be used. The paper presents discussion on some problems in applying inverse formulation of back analysis to a roadway driven in an in- homogeneous rock mass. The back analysis is formulated by 2-0 finite element method. The inverse procedure is carried out using a microcomputer, but for the multi-rock layer, a larger computer or a main-frame computer is used due to an iterative procedure. |
