A view of a junction room in Nevada's Larkspur Mine, a long defunct silver mine from the late 1800s that has multiple adits, however there are two main ones that have significant workings, of which include a multitude of stopes, ore chutes, raises, & winzes, not to mention a few false floors as well that could be fatal. Here one can down at a manway winze leading presumably to another stope down a lower adit. The ladders look very unstable but actually they were still quite sturdy, though I didn't risk downclimbing. There was a strong draft of wind funnelling down the winze to which this might connect w/ the lower adit. A few mining terms: Adit A horizontal passage leading into the mine, not to be confused w/ a "tunnel", which would have an opening out the other side. Adits are sloped slightly upwards to allow for drainage of groundwater. Crosscut A horizontal opening that does not run along the vein. Typically a shaft will lead to crosscuts at each level that give access to drifts along the vein. Crosscuts typically run straight as an arrow through worthless rock. Drift A horizontal opening that runs along the vein. Typically there are many ore chutes from stopes above, and the drift will wander to follow the vein. Level If you follow a ladder down a shaft, you will arrive at horizontal workings every 100 feet or so, and these are called levels. The levels have a station near the shaft, and are named by the distance down the shaft. Manway Any kind of passage with a ladder in it could be called a manway. Shafts are divided into "compartments" and one of these is very often a manway. Sometimes the manway of a shaft is crowded with pipes and cables and such. Ore chute A "spout" built of wood used to load broken rock from above into waiting ore bins. Raise A raise is like a shaft that starts undergound and goes upwards. Typically a ladder next to an ore chute along a drift goes up a raise and gives access to a stope above. Square s
