What Is OpenPit Mining? (with picture)
One of the advantages of the openpit mining system is the fact that it is not as capital or labor intensive as the underground method of mineral or precious metal and stone extraction. The process of openpit mining is precipitated by the analysis of the area in order to determine the presence of the desired material that may be coal or ore.

mining
In openpit mines this consists of building access roads and stripping the overlying waste material in order to expose the ore and establish the initial bench geometries. For an underground mine the development stage is considerably more complied. Some of the development components of an underground mine are illustrated in the figure.

Basics of an open pit mine
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.

GroundWater Problems in OpenPit and Underground Mines ...
Ground water constitutes a significant operational problem and potential hazard in openpit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of openpit mines, justifying measures to reduce groundwater pressures in their vicinity. The principal hazard in underground mining and tunneling arises from .

Openpit (OP) and underground (UG) mining are usually used to exploit shallow and deep ore deposits, respectively. When mine deposit starts from shallow subsurface and extends to a great depth, sequential use of OP and UG mining is an efficient and economical way to maintain mining productivity. However, a transition from OP to UG mining could induce significant rock movements that cause the ...
