SURFACE MINING – Mining Engineering Site
· Bench – One of two or more divisions of a coal seam separated by slate or formed by the process of cutting the coal. In open pits, benches are different mining levels formed as the rock is mined in horizontal slices. Berm – A pile or mound of material capable of restraining a vehicle.

MINE PLANNING BASICS FRIDAY – WHAT'S THE DIFFERENCE ...
· My kind associate Kenn Smart allowed me to use this graphic from his collection of BASICS of EARTHMOVING booklets. Note how the definitions change from the final pit outline to the active pit outline... And to complie matters even further, the safety berm also comes into play... Comments most welcome. Enjoy your Friday friends!
Berm
A berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortifiion line, a border / separation barrier for navigation, good drainage, industry, or other purposes.
Mining Road Berm Open Cut
In openpit mining, a berm refers to dirt and rock piled alongside a haulage road or along the edge of a dump point. Intended as a safety measure, they are commonly required by government organizations to be at least half as tall as the wheels of the largest mining machine price. meaning of bench, berm, bench toe in mining « Mining.

S Coetsee Reutech Mining, South Africa. The empirical derivation of the minimum berm width and the formulae presented by the various design criteria are different due to the input parameters selected, thus resulting in a range of minimum berm widths that can be calculated for the same set of rock mass and geometric conditions.
A better way to presplit
· Furthermore ROC rigs are not just better at presplit drilling, they can also be used for a variety of other tasks such as leveling benches for the large rigs, complementary drilling of buffer holes up to 203 mm, drilling long, horizontal dewatering holes or using the Reverse Circulation (RC) option for inpit grade control.
Bench (geology)
In mining, a bench is a narrow, strip of land cut into the side of an openpit mine. These steplike zones are created along the walls of an openpit mine for access and mining. See also. Raised beach, also known as Marine terrace – Beach or wavecut platform raised above the shoreline by a relative fall in the sea level; Piedmonttreppen ; Strandflat – Landform typical of the Norwegian ...

Open Pit Mine Dump Design Course using Geovia Gems
Open Pit Mine Design is a twoday course designed for mine planners, mining engineers, and geologist who are responsible for activities that require them to design and manage pits, ramps, switchbacks, slots, and waste dumps. It is ideally suited to those from industry who wish to gain a more in depth knowledge of modern mine planning and design theory and software tools.
