Input Data
Overview
Взрыв4D accepts four groups of data required for numerical simulation of blast-induced rock mass fragmentation.
Block Geometry
Description of the physical configuration of the block prepared for blasting:
| Parameter | Description |
|---|---|
| Coordinates | Spatial coordinates of the block boundary |
| Drilling Parameters | Depth and location of blast holes |
| Surface Configuration | Terrain and surface parameters of the open pit |
Geological Block Model
A model containing the quality characteristics of the ore:
- Grade of ore components per block
- Classification of ore and waste rock
- Spatial distribution of characteristics
Geomechanical Mass Properties
| Parameter | Description | Units |
|---|---|---|
| Density | Bulk density of the rock | kg/m³ |
| Strength | Uniaxial compressive strength | MPa |
| Elastic Modulus | Young's modulus | GPa |
| Fracturing | Rock mass fracture characteristics | — |
Simulation Accuracy
High accuracy of results is achieved when correct geomechanical data is available. The quality of input data directly affects the reliability of the forecast.
Drill-and-Blast Parameters
| Parameter | Description |
|---|---|
| Hole Depth | Depth of blast holes |
| Initiation Network | Charge connection and delay scheme |
| Charge Design | Type and placement of charges in the hole |
| Explosive Properties | Explosive characteristics (density, detonation velocity) |
Input File Formats
Data is uploaded via the application's web interface. Supported formats:
- CSV — tabular data (coordinates, parameters)
