Invesitgation into the structural behaviour of mine brick barricades

Abstract

The structural behavior of mine brick barricades in underground mines was investigated. The details of a barricade, measuring 6m wide, 5.3m high and 400mm thick was discussed. It was stated that the failure mode was dependent on the compressive capacity of the masonary due to arching action and the assumed cracking pattern of the barricade. Results from the destructive test on a structural model showed that the predicted capacity based on the material properties was lower than the measured value.
