what is batter angle mining

Open-Pit Mining Definition | Anglo American

Open-pit mining is a surface mining method where rocks & minerals are removed from an open pit near the earth's surface. ... The walls of most open-pit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site. The incline section of the wall is called the 'batter,' and the flat part of the ...

This should not be confused with 'overall slope angle' which is the angle between the lowest toe and the highest crest inclusive of any haul roads (Slope Stability in Surface Mining; W.A. Hustrulid p48). This formal definition of 'overall slope angle' is how we would normally think about the slope of an ordinary hill.

Basics of an open pit mine - Mine Engineer

Every angle is comprised the result of a set of 3 points being compared. Transit levels can be used to help you figure out the angle created by a set of three objects, and the distance between each object relative to the other two. Once you know these measurements, you can plug the numbers into the above equations, and figure out the slope.

constraining the slope angle calculations to one cell length (or 1.4 cell lengths in the diagonal) in a downhill direction. This slope angle also corresponds to the direction of overland flow from the cell in question. For more information regarding different slope angle calculations, see Dunn and Hickey (1998) and Srinivasan and Engel (1991).

May 10, 2015· Inter-Ramp Angle (IRA): this is the slope angle in degrees, either as a calculated value or an input. When double or triple benching, sometimes a small 1-2m berm may be left between benches due to the inability of the blasthole drill to get right against the pit wall when drllling off the next bench.

SLOPING AND BENCHING SYSTEMS

Wall Batter. Segmental retaining walls are generally installed with a small horizontal setback between units, creating a wall batter into the retained soil (ω in Figure 2). The wall batter compensates for any slight lateral movement of the SRW face due to earth pressure and complements the aesthetic attributes of the SRW system.

Guideline for Batter Surface Stabilisation using vegetation

The batter, or angle, of the wall, must be precisely calculated so as to ensure that the wall remains both upright and secure. An experienced construction engineer will be able to carry out such a task to a high standard, but a ley person might struggle. Nevertheless, battered walls can look marvellous in the right setting, and increasing ...

Mar 02, 2016· Open-pit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is […]

Batter (walls) - Wikipedia

Definition of Batter in Construction To batter a wall or an excavation is to angle the slopes of the excavation or the wall at an angle greater than 90 degrees. The battering of a retaining wall means that the face of the wall will slope away from the front of the wall and towards the material being retained or …

Battered Wall | Industry Resources | Groundforce

The standard batter angle for these structures, is 60°. A width of 2m across the top, which is crowned with a crossfall of 2%, is specified. Crossfall across the top is important to prevent pooling of water on the surface, seepage into the windrows and, eventually, weakening of the structure due to water infiltration.

The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.
