Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called openpit or opencut mining.
Surface mining. Opencast mining, otherwise known as surface mining consist of three different techniques: strip mining, openpit mining, and mountain top blasting. In general, the three processes include breaking up soil and rocks via explosives and then removing debris until coal seams are exposed.
Welcome back to the surface mining model. In the previous topic, we learned about different types of surface mining operations, about equipment, about different methods that are commonly used to extract coal or different ore deposits. It''s not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic, we will go through some of the ...
Surface Mining Techniques Surface mining of coal is characterized by the use of large, capitalintensive and efficient mining equipment. First, the overlying soil and rock layers (overburden) are removed. The coal is then fractured with explosives or machines, and loaded onto vehicles for haulage from the mine site. Finally,

The openpit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.
equipment selected. Moreover, equipment selection directly affects the pit design and production planning. In open pit mining, equipment selection is made according to many factors related to the ore and mining conditions. These factors can be qualitative and quantitative in nature. The main purpose of equipment selection is to choose the
Openpit, opencast 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 mines are used when deposits of commercially useful ore or rocks are found near the surface.
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.
