For example, the elevation grade of a street could be 6.2°, meaning the street tilts upward 6.2° from horizontal (the horizon). In other words, you’re traveling uphill. When calculating elevation slope in degrees, it’s helpful to think of the problem as a right triangle. Using basic trigonometry, you can find grade in degrees quickly.

Mining is done by block caving.In 1980 the cavity produced by the panel caving broke through to the surface, producing a large glory hole (subsidence) on the side of Red Mountain.. The ore is carried by a 15-mile (24 km) conveyor belt system extending through a 10-mile (16 km) tunnel beneath the Continental Divide and then five miles (8 km) overland to the ore processing mill near Parshall

Which layers to mine? Diamonds are found only in the bottom 16 layers of the map, so this is where you will concentrate your mining. There is a lot of lava in layers 5–10, including large lava-lakes. Some players prefer to avoid this by staying on layer 11 and above ( y=13.6). I prefer to mine at all levels, turning back when I hit lava

In general, the higher the rank of coal and the greater the depth of coal seam, the higher is the gas content of coal. Gas content of coal seams vary from a few ft 3 /t to 800 ft 3 /ton for depth up to 3000 ft. Coal seams are the source as well as the reservoir for all gases.

The depth of Shaft #2 is 2,258 feet below ground surface. The Norton Mine is a system of rooms and pillars. Initially, the rooms and entries were on 80-foot centers with entry dimensions of 28 feet wide by 25 feet high and room dimensions of 40 feet wide by 50 feet high.
The cover (overburden) gives the approximate depth (in feet) from the surface to the mine void. This is calculated by subtracting the coal seam elevation from the surface elevation. The status of mining at the site being researched is indicated in this section. If "Coal Seam Non- Existent" is indicated, then it could mean the particular coal
Mining started from the 440 metre level and the 650 metre level. Production will be at the nominal rate of 5,000 tonnes per day with four mining horizons starting on the 230 metre level, 440 metre level, 650 metre level and 800 metre level.
Apr 28, 2011· I mine for iron at y50. This is sufficiently deep that running tunnels under lakes shouldn't be a hassle, but not deep enough that iron spawns will start "competing" with other resources. You also mine plenty of coal as well. As well, I'm convinced you hit more ore nodes tunneling diagonally than you would making a straight tunnel.
