Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. 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.

Mathematical Optimization Models and Methods for Open-Pit
In this thesis, we study the open-pit design problem, the open-pit mining scheduling problem, and the open-pit design problem with geological and price uncertainty. These problems give rise to (mixed) discrete optimization models that in real-life settings are large scale and computationally challenging.

1.1 PHASES OF A MINING PROJECT elaw
1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
Open Pit Mine Planning and Design, Third
Open Pit Mine Planning and Design is an excellent textbook for courses in surface mine design, open pit design, geological and excavation engineering, and in advanced open pit mine planning and design. The principles described apply worldwide. In addition, the work can be used as a practical reference by professionals.
Open-pit mining Wikipedia
Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.

batters and berms above active mining horizons. This requirement is more important when the pit wall design does not lend itself to visual monitoring easily, and when the "after mining" status of pit wall berms do not conform to the pit design (eg when batter crests collapse or berms are filled with rock rill).
