esp. puttin in a 96. We don't use those where i'm at, but it all depends on how hard the roof is, can't drill too fast or you'll just shred bits and waste more time.
I'd say its a Fletcher from what I seen. Must have pretty good top to use drill pot to torque the bolt. Are they putting in a 48in bolt? No fast feed? We got our glue from DuPont and times we had to use fast feed before glue setup
That's me in the video. Again, sorry for the lighting. This particular bolter doesn't have the lights mounted in the best places. Yes, it is a Fletcher, a Roof Ranger 2 (the higher set version for taller coal mines). This was taken at a mine in Ohio where we were recovering a highwall miner that had been trapped by a very large roof fall. It was lower top than what we normally work in, basically because we just cut what we had to in order to get the highwall out of there.
It was pretty hard, decent top, but this is a typical amount of time it takes us to drill for a 96 inch (8 ft.) roof bolt. As you can see, I had to bend the bolt almost in half to get it in. You can also see me using glue, but we cannot fast feed through our glue or the bolt will bend over as the glue is the same width as the hole. & we use expansion Type B bolts. We mostly use our fast feed for dropping the steels & running bolts up to the glue line faster.
Be careful down there buddy. From an old roofbolter in So. IL, Debbie

@chadbrisby - Not sure who you are, but clearly, that is as fast as that thing would drill.

at a first glance that looked like a cable bolt steel. Try puttin in 72's in 36 inches those are a fun time.
