diamond hitch

I hoped a cautionary statement would suffice - maybe not. A few things to think about. I walked into a drift about 800 ft and hit a wall of pressure on my lungs. Pyrite on bedding planes consumed the oxygen. We had enough warning to get out while we could.
we walked through some water in a long drift in the Okanogan. That released hydrogen sulfide that poisoned the air we had and we were lucky to get out alive.
A diamond drill crew in the Cascades were setting up in an old drift. One of them lit a cigarette and blew them out the portal. Methane can come from the rock and from rotting timbers.
Had an assistant excited to find chrystals as we worked down a drift. He failed to note the timbers on the floor and fell down a winze and broke his neck.
we crawled into small portal to map some old workings. Getting in was easy but on the way out the portal caved trapping us inside. Since we had a surface observer we got out.
I could go on but hopefully you get the point. Old mines are not a problem with proper training, tools, and experience. For the public - stay out.
