Tangram

Loading 0%

Tangram is the most advanced software to identify instabilities in a mine. Using topographical surveys and slope designs, Tangram identifies which blocks are unstable and geolocates them for swift, targeted removal.

MAIN BENEFITS

Tangram allows you to boost operational continuity by reducing the number of geotechnical events caused by falling rocks. Moreover, it allows you to get closer to optimal slope angles by taking into consideration the formation of instabilities and recommending better slope designs.

SAVE TIME AND EFFORT

Tangram saves you hours or even days of work by automatically identifying instabilities and calculating their safety factor and failure probability.

BOOST SITE SAFETY

Tangram uses site-mapped structures to detect instabilities. Customers now know where the unstable blocks are located inside their pit and how likely they are to fall and can take appropriate measures, thereby improving site safety.

IMPROVE SLOPE DESIGN

Tangram allows you to assess potential berm losses in actual or designed slopes and see the resulting slope once they are removed. This allows the user to assess multiple designs and get closer to the optimal slope design.

BETTER STRUCTURE DATABASE MANAGEMENT

Tangram centralises all structural and fault surface maps in a single database which makes it possible to manage mapping history, related structures, to change structure’s attributes, and to assign parameters such as cohesion, friction angle, structural set, and length to surface maps.

FEATURES

Tangram automatically detects instabilities and calculates the safety factors and failure probability. It also displays what the resulting slope will be once all the unstable blocks are removed. These functions are highly intuitive and user-friendly which makes Tangram an easy-to-use tool that provides quick support to geotechnical engineers and planners.

AUTOMATED & GEOLOCATED DETECTION OF INSTABILITIES

Tangram automatically detects potential instabilities that may have formed by mapped structures on site and geolocates them. It can detect all flat faults, wedges, and complex blocks (polyhedral) made up of three or more structural planes.

SAFETY FACTOR & FAILURE PROBABILITY CALCULATION

Tangram will calculate the safety factor and probability of failure for each block found on the slope. You can then filter and color code the blocks according to their safety factor, failure probability, or other variables such as volume and tonnage.

DESIGN PARAMETERS ASSESSMENT & RESULTING SLOPE

Tangram can be used to model and assess slope designs to detect instabilities by changing design parameters such as, bench face angle, berm width, and bench height. Instabilities detected on an actual or planned slope can be removed to obtain and see what the final slope would look like.

EXTEND & SIMULATE STRUCTURES

Tangram can be used to extend structures mapped on the last bench onto a lower slope design to predictively study the instabilities that will be formed. Users can also randomly create structures based on the mine’s structural sets, populate a slope design with simulated structures, and assess the designs.

MAPPING

Tangram allows you to upload photogrammetric images of the slopes and merge them to the mine survey which provides support for remote structural mapping, especially in inaccessible areas. You can also place structures onto each survey and model new fault surfaces.

ADDITIONAL TOOLS

Tangram can be used to trace structures on slopes; view structures in a stereographic network and select them for system assignment; triangulate, divide or compose actual surveys and design meshes; view cross-sections, contours, and cuts; upload geological and geotechnical models, and other geometries (e.g., mining plans, underground infrastructure or piezometric-phreatic surfaces); and export different geometries/meshes and analytical results.

FAQ

RocPlane and Swedge allow users to model only a flat fault or wedge on an ideal slope. Tangram identifies every flat fault, wedge, and block made up of three or more structures geolocated in an actual survey.

Leapfrog is a geological modelling software that produces lithology, alteration, and mineralization volumes; it also allows users to model and map fault surfaces that alter how these bodies are arranged. Tangram allows users to model and map fault surfaces since it is a software meant for mining and that identifies instabilities formed by minor faults and structures.

Tangram automatically identifies instabilities and their associated safety factor and geolocates them, allowing users to decide whether to remove instabilities bench by bench or make other operational safety decisions. Tangram also boosts operational continuity by reducing the number of unexpected geotechnical events because it identifies and predicts instabilities, and therefore allows users to consider numerous designs with different slope angles and berm widths, so that they come closer to defining the optimal parameters required by their business while forming the fewest number of instabilities.

For flat faults, Tangram identifies structures that intersect the topography and evaluates the azimuth difference between the slope and the structure according to the limit input by the user for forming flat faults. It will then create liberating planes to simulate instabilities alongside the topography.
For wedges and blocks in three or more planes: Tangram intersects all structures considered in the topography and illustrates where closed polyhedrons form with the topography (stellated polyhedrons).

Yes. You can use Tangram to create new structures by mapping on the slope.

Yes. Tangram can upload three types of photogrammetry files: surfaces, one or more images making up the texture of a surface, and a file that links texture with the surface (.mtl files).

Yes. Tangram allows you to create disks on a slope according to dip distribution, dip direction, spacing, and longitude. Each one has an associated mean and standard deviation which simulates the characteristics of the structural set you want to represent.

Yes. When identifying instabilities, Tangram can use minor structures from a structure table or .csv file, and medium and major faults modelled with .dxf files as input.

Tangram can be installed on any computer, laptop, or notebook computer. You do not need a server or any other connection. Tangram is an executable file that installs in just a few minutes.
