Software for the determination of OPTIMAL profiles for SLOPEs and pitwalls
Copyright: all rights reserved
Version 0.6 - March 2021
OptimalSlope is completely based on a easy and intuitive text interface.
The software asks to input the email address where OptimalSlope will send the simulation results.
(note: this is the only way that the software has to provide outputs to the user)
Provide an email address to send the simulation results: firstname.lastname@example.org
Is email@example.com correct (T,F)?
Then OptimalSlope asks the geotechnical input parameters of the simulation
Input simulation parameters...
- Overall slope height [m]: VALUE
- Number of segments defining the optimal slope profile (number of benches): VALUE
-> The bench height is: X m
- Target FoS: VALUE
- Number of different Generalised-Hoek-Brown geomaterials: VALUE
Unconfined Compressive Strenght i [mPa]: VALUE
Geological Strenght Index i: VALUE
Material constant for the intact rock (mi) i: VALUE
Damage factor i: 1
Soil unit weight i [kN/m3]: VALUE
Maximum confinement stress to calculate the equivalent Mohr-Coulomb parameters,
if the Renani & Martin relationship has to be used input NaN i [mPa]: VALUE
Bench face angle i [deg]: VALUE
Berm width i [m]: VALUE
- Number of different Mohr-Coulomb geomaterials: VALUE
phi i+1 [deg]: VALUE
c i+1 [kPa]: VALUE
Unit weight i+1 [kN/m3]: VALUE
Bench face angle i+1 [deg]: VALUE
Berm width i+1 [m]: VALUE
Later, OptimalSlope asks to define how the geomaterials defined before are distributed from the topographic
surface and it will show the options available.
(note: if the user defined only one geomaterial, OptimalSlope will assume that the slope under design is homogeneous and won’t show this menu)
Define how the materials are distributed starting from topographic surface
(materials available: i i+1 i+2):
Material for the layer going from dZ_1 m to dZ_2 m: VALUE
Material for the layer going from dZ_2 m to dZ_3 m: VALUE
Material for the layer going from dZ_3 m to dZ_4 m: VALUE
Material for the layer going from dZ_4 m to dZ_5 m: VALUE
Successively OptimalSlope asks the initial OSA which is the starting point for an
iterative procedure used to obtain FoS(OSA optimal profile) = target FoS.
- Overall Slope Angle starting [deg]: VALUE
(note: This value should be taken from the corresponding planar slope profile case where FoS(OSA planar case) = target FoS)
OptimalSlope has the possibility to define the presence of a road (or more) at different slope heights.
- Road width (set NaN for no road) [m]: VALUE
(note: If a value of road width is inserted, OptimalSlope asks the vertical position of the road measured from the crest of the slope. If the user wants to insert more than one road the values of road position must be enclosed by squared brackets. On the contrary, if the user set NaN, as road width, OptimalSlope won’t show this option)
Another scenario that OptimalSlope can model is the presence of a distributed surcharge applied on the crest of the slope.
- Road position (vertical distance from the crest - values beween [ ]
for more roads): VALUE
Do you want to apply a distributed surcharge? [y/n] y
- Unit weight of the distributed surcharge [kN/m3]: VALUE
- Inclination of the triangular component of the distributed surcharge [deg]: VALUE
- Height of the distributed surcharge [m]: VALUE
- Distance between the crest and the distributed surcharge [m]: VALUE
(note: if the user specifies 'n' when asked about the presence of the surcharge, the submenu won't be displayed)
OptimalSlope has the possibility to define non standard settings in a final submenu
Do you want to set additional options? [y/n] n
(note: for more info about the available additional settings please refear to the user guide)Download the full USER MANUAL
Finally, OptimalSlope will ask confirmation for the data set as input and it will
start the search of the optimal profile with the input parameters defined before.
The results will be emailed to the address provided before the parameters definition.
OptimalSlope produces depth varing pitwall as output of the optimisation.
To integrate the optimal slope profile into Pit Optimisers, the user needs to define horizontal slope regions within the block model, which are used to assing depth varying slope angles.
The procedure to create horizontal slope regions within the block model varies between the different General Mining Software (GMS) and won't be discussed in this guide.
Inside the Pit Optimiser, the user need to select the option to define slope angles by "zone numbers in the Model file" and, for each slope zone identifier, assign the local inclination given by OptimalSlope.
In the figure above it is presented a possible results of OptimalSlope with the local inclinations (numbers on the right of the slope profile) and the slope zone identifier used in the GMS (numbers on the right of the slope profile). Note that zones with same local inclination have the same slope zone identifier.
