Cemented Paste Backfill (CPB) Material Properties for Undercut Analysis

Cemented Paste Backfill (CPB) Material Properties for Undercut Analysis

A longstanding mine backfill design challenge is determining the strength required if the (partially) cured backfill is subsequently undercut. Mitchell (1991) called the undercut backfill a sill mat and proposed an analytical solution that is still often used, at least for preliminary design, and ha...
