Modeling

Calculation Stages​

Взрыв4D performs simulation in several sequential stages:

1. Fragmentation Physics Simulation​

The first stage calculates the physical fragmentation process:

  • Energy Propagation Front — calculation of blast energy propagation through the rock mass
  • Fragmentation Zone — determination of the fragmentation zone and its boundaries
  • Ballistic Simulation — calculation of trajectories and displacement magnitudes of fragmented material

2. Muck Pile Model Construction​

The second stage builds the model of the displaced mass:

  • Muck Pile Configuration — calculation of the muck pile surface geometry
  • 3D Model — construction of a volumetric model of the displaced rock
  • Displacement Forecast — determination of the direction and magnitude of displacement for each block

3. Quality Parameter Forecast​

The final calculation stage determines the distribution of the ore:

  • Ore Model Transfer — migration of the quality block model from the in-situ mass to the muck pile
  • Mixing Calculation — determination of the degree of mixing between ore and waste rock
  • Loss Zones — identification of ore loss and dilution zones

Calculation Model​

Model Characteristics

The fragmentation model assumes a quasi-static calculation without detailed consideration of the detonation wave. This approach provides a balance between accuracy and computational speed for drill-and-blast planning tasks.

Calculation Parameters​

Before launching the simulation, the user configures parameters through the interface:

  1. Input Data Selection — uploading geometry, geological model, geomechanics, and DBO parameter files
  2. Simulation Parameter Configuration — calculation precision, discretization step
  3. Output Format Selection — format of result files and visualization parameters
  4. Start Calculation — initiating the computation

The calculation runs on the server in Docker containers. Computation time depends on the model size and hardware configuration.
