Underground Mining Applications

Automated and adaptable model extraction sequencing, assigned using geometry files developed in CAD or mining packages. Extraction steps of any time period can be applied to suit the situation being analysed.

Optimise model processing times, removing historic extraction in the first stage of modelling, allowing more time to focus on the steps that matter.

Stope backfill is sequenced automatically, custom delays can be assigned by the user. Backfill properties can be assigned separatelyusing the perfectly plastic Mohr-Coulomb model or Elastic material model. StopeX allows up to 20 separate backfill ‘rules’, and each rule can be used to define different fill properties or the timing/sequence of fill placement.

Meshing is one of the most time consuming and difficult tasks in modelling. StopeX has a built-in routine that streamlines the octree meshing process. This can generate an optimised model mesh using an iterative process where zone sizes increase or decrease to find the model mesh that has sufficient resolution for accurate analysis while ensuring it does not exceed the user-defined maximum computer RAM.

Model domains, Faults and area of interest assignments are handled automatically using the specified geometries. Groups are organised into ‘slots’ ensuring consistency across multiple models, and simple interrogation of model results.

Transfer existing models from MAP3D to StopeX for analysis of rock mass response without adding to your workload.

If you are comfortable generating your own mesh, skip the automated meshing steps and import a custom mesh from a file.

IUCM serves as the built-in constitutive model for StopeX and aims to account for all experimentally and operationally documented rock mass behaviours as a function of the acting stresses and accumulated strain.

Strength Anisotropy, where present, plays a critical role in the rock mass response. IUCM incorporates strength anisotropy with the addition of three simply acquired parameters.

StopeX assigns the in situ stresses in the model according to principal stress gradients provided by the user, or amore simplistic method where only horizontal to vertical stress ratios and the trend of the major horizontal stress are provided. The interface also allows the user to include a locked stress for each principal stress component, which will add a constant stress value at ground level elevation.

Fixed boundary conditions are automatically applied on all boundaries of the model. When a topography is included, the topography surface remains free allowing for assessment of underground-surface interactions.

Save time and resources by taking advantage of Cavroc’s Aurora cloud computing options to process models faster than ever before.

Have your model reviewed by an expert member of the Cavroc team. Rigorous error checking and evaluation of your modelling inputs ensures your analysis can continue smoothly.

Geometry preparation can be a time consuming and challenging part of the modelling process. If you are pressed for time or resources, Let us take care of it for you.
