Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .
Walls constructed in this manner are an effective obstacle to vehicles, including most armoured fighting vehicles, but are easily crossed by infantry. Because of the ease of construction, such walls can be made hundreds or thousands of kilometres long. A prominent example of such a berm is the 2,700 km (1,700 mi) Moroccan Western Sara Wall.
Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic
The final pit slope and geometry should ensure that the pit walls are structurally stable and allow for the placement and long term stability of the rock fill (overburden) and soil required for revegetation. Plans should include crosssections showing rock faces, benches and thickness of rock fill and soil cover placed on rock surfaces.
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.
Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.

Stopping distance is the minimum distance needed by a vehicle to stop, when travelling at a design speed, to avoid an oncoming hazard. The distance takes into account driver reaction time, the retarding action time delay for any vehicle and the time taken for the vehicle to come a complete stop.

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ead of the face and the back abutment, that is, the settled packs behind the face.
