description.abstractImportance of blast-induced rock damage (BIRD) assessment for increased roadway stability is discussed. Near-field PPV estimated has been utilized to fix up damage threshold levels for categorizing the degree of rock damage. Influence of roof RMR(Rock mass rating), PPV and maximum charge per delay on blast-induced rock damage (BIRD) is also analysed. Limiting maximum charge per delay is computed for controlling roof stability problems.en
