Please PM if the CNCC wants it back.
That looks like a perfectly good p hanger cut off flush with the rock rather than removing by drilling out the glue and pulling the anchor so the hole (and the anchor!) can be used again in the future.View attachment 21308a member from Cardiff found this piece of bolt in Simpsons at stake pot

This anchor has been cut off. It is not a metal failure of any sort.I hope I am being over cautious in seeking confirmation that it was not a metal fracture failure? If so that would probably be a first amongst the thousand plus placed DMM Eco anchors and a major cause for concern. (It took over 4 years to sort out a previous metal fracture case and possible causes!)
I have used the anchor puller with Sam to remove P-bolts in caves. It has been shown it to be a feasible method.I don't think there's any need to go through the (lengthy) rigamarole of extracting an anchor from a hole if there is no need to re-use the hole. I haven't done it, but I believe it's a faffy, involved process that involves dragging heavy kit down a cave, depending on technique may not always work and/or may involving drilling additional holes (and burning through drill bits in the process), and may not be possible anyway (depending on the placement of the anchor and how the puller would sit).
It's probably still better to put a new anchor in a clean hole anyway.
An anchor that has been pulled out needs to go in the bin (I'd be very surprised if the head wasn't very deformed at the very least).How do you train to be an anchor installer? I remember the IC anchor sessions being done into a nice big block of concrete, or a very straight bit of rock anyway. Would anchors that have been pulled out be useful for new people coming into the role so they can practice installing anchors that are not reducing the available to se stock?
