In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.
The cover (overburden) gives the depth (in ft.) from the surface to the mine void. This is calculated by subtracting the coal seam elevation from the surface elevation. For the Pittsburgh coal seam of PA, the depth of cover could range anywhere from 0 ft. to as much as 1000 ft.
Other than that, just use efficient mining and hope for the best. ... Statistically, the best place to search for diamonds is in a 2x1 "grid" pattern at the 10-15 depth level.

Mining with this pattern is very efficient, and you will miss only the smallest ore veins. The exception to this is if you are mining for Emeralds in Extreme Hill biomes. Emerald ore is present as single blocks, so if you really want to get all the emeralds you have to place your tunnels 2 blocks apart.
The average mining depth of Great Noligwa is 2.4km below surface and the maximum mining depth is 2.6km below surface. The mine primarily exploits the Vaal Reef (VR) with a twin shaft system. The Crystalkop Reef (CR) comprises the secondary economic horizon for the mine.
Examples of custom elevation surfaces include one that defines the depth of a geological strata, or one that defines the height of a restricted airspace. You can set the height of feature layers to be drawn on the ground, relative to the ground, or at an absolute height from the elevation surface.
Data mining and OLAP can be integrated in a number of ways. For example, data mining can be used to select the dimensions for a cube, create new values for a dimension, or create new measures for a cube. OLAP can be used to analyze data mining results at different levels of granularity.
Groundwater Mining: Withdrawal (removal) of groundwater over a period of time that exceeds the recharge rate of the supply aquifer. Also referred to as overdraft or mining the aquifer. Monitoring well: A non-pumping well, generally of small diameter, that is used to measure the elevation of a water table or water quality. A piezometer, which is ...

Obtaining resources from ores is as simple as mining them (this is not the case for iron and gold ores, which must be smelted). Coal, diamond, emerald, and nether quartz ores drop 1 unit corresponding raw materials. Redstone ore drops 4-5 redstone dust, and lapis lazuli ore drops 4-8 lapis lazuli. Note this can be increased greatly with fortune.
