What are Ramps and How to Design Them?
Always take the height of the ramp into consideration while fixing the final slope. Example: Design a ramp to overcome a height of 55 cm. Given Data: Height of ramp, h = 55cm. Take, Slope = 6%; Slope of the ramp (%) = (h/d )x100. 6 = (.55/d) x 100. d = 9.12m. Hence, the horizontal plane for this ramp is 9.12m.

7.2.3: Pit Terminology | GEOG 000
Crest: Exterior vertex formed by the intersection of the bench floor and bench face. Bench width: The distance between the crest and the toe measured along the upper surface. Bank width: The horizontal projection of the bench face. There are two types of benches in each open pit mine: working benches and safety (catch) benches.

Ramps, slopes, gradients, inclines and levels Chambers McMillan, architects
The standard accessible ramps with the USA is recognised as 1:12 within all the states. This ramp can be an unbroken single flight up to 30 feet/ 9 metres. They suggest that shorter ramps can be used up to 1/6 gradient with the maximum steepness being 1:4 which is an unoccuoied chair being loaded into an accessible vehicle. European examples
The Spiral Ramp Theory
The Spiral Ramp Theory. A spiraling or winding ramp may have been used to prevent the problems associated with a single long ramp. This would have taken up less space and allowed workers to move up the face of the pyramid with ease. The remains of a small ram at Giza supports this theory. < (2 of 3) Next argument >.
Optimum ramp design in open pit mines
The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational costs. Because in-pit ramps require the removal of a considerable amount of non-valuable material (stripping), we discuss two ...

18 Spiral Ramps. I deliberately picked spiral ramps as opposed to spiral staircases, since they include buildings whose entire form is determined by the ramp rather than being merely a feature.

networks. The proposed model assumes that ramp links are straight lines, so the pro-posed theory and algorithm can only be applied directly to underground mines in which terminal points are in a near-horizontal plane to satisfy the gradient constraint, i.e., they cannot be used in mines with several production levels.

Decline design in underground mines using constrained path optimisation
A key design consideration is that the decline must be navigable by trucks and mining equipment, hence must satisfy both gradient and turning circle constraints. The decline is modelled as a mathematical network that captures the operational constraints and costs of a real mine, and is optimised using geometric techniques for constrained path ...
Techniques in Underground Mining
The ramps are often driven in an upward or downward spiral, similar to a spiral staircase. Ramp excavation is a routine in the mine's development schedule and uses the same equipment as drifting. Figure 2. LHD loader. . Raising. A raise is a vertical or steeply-inclined opening that connects different levels in the mine.

The maximum flight length for a particular gradient can be interpolated as follows: 3m long for a gradient of 1 in 13, 4m long for a gradient of 1 in 14, and so on. 4.3.12 Width of ramps flights The width of a ramp should relate to the intensity of use.
Garage ramp: slope, width and design guidelines
The maximum slope for a garage ramp should be within 20%, as indicated by most national regulations worldwide. However, a 20% slope that is not well connected will avoid damaging the bottom part of the car. Therefore, a slope of 16% with a maximum gradient of 6% is recommended.

Ramps and steps design and planning
A slope at the steeper end of this range can still be challenging, especially over distance, and incorporating level areas and seating is important. A gradient steeper than 1:20 (5%) is considered a ramp. A ramp gradient should not exceed 1:12 (8%). Avoid abrupt changes in gradient and aim for smooth gradual changes.
