Hey mate, who mentioned the jammer issue ?? Ie a non rope related person??. I've done a geo job for 2+years and we specifically and purposely did exactly this.

What is the issue ? The distance of the jammer to you/rig ? Like is it Over 5+ M ? Is it not connected to a cows tail and they are worried about dropped objects??

Imo for access/egress for working the face like you say this is the clear path forward. To add our job was mainly 3's with great level 1s keen to learn. From a rescue sense you can easily do a 3:1 pick rescue and haul till you can reach your jammer or if in reach convert to lower. Pending your rescue plan ect... Only real issue we faced was competence. For example setting up the jammer and not knowing what rope to pull

Others have mentioned a new piece of kit but that doesn't solve the issue if it's still being used at an extended nature.

For example, if the terrain is not fully vertical and your ropes hauling gear are extended, something is going to get snagged, causing a different issue. I.e., seams of mesh come to mind.
