Load loss from rock-bolt anchor creep
To determine in what part and to what extent creep or movement exists in installed rock-bolt anchor and effect of creep or bleed-off on tension load on rock bolt, as well as effect of normal mining activity on rock-bolt load and anchor, Bureau of Mines conducted tests which revealed that most load loss resulting from static loading is due to slippage and seating of serrations on anchor shell into drill-hole wall; dynamic loading, due to blasting or ground movement will cause anchor wedge plug to seat in anchor shell.
