Instrumented Rockbolt with Dial Depth Gauge For Testing Lab Description and Specifications for Lab Tenders
Instrumented Rockbolt with Dial Depth Gauge.
Rockbolt provide a convential means of strengthening underground
openings and stablizing cut slopes in rock. It is therefore important to
check that installed Rockbolts will not fail through over loading.
The Instrumented Rockbolts comprise a hollow ribbed steel bar fitted with upto four internal extensometer rods. Movement of one or more of extensometer rods in relation to the measuring head is monitored by inserting a dial depth gauge into the appropriate aperture in the measuring head. Applications: Measurement of Rockbolt loads. Monitor the behaviour of jointed roof and floor strata during various mining/tunnelling stages. To determine the magnitude of loads on roof supports.
