Determining constraints and equipment fleet configuration for one of the biggest open cast coal mines in Southern Africa. We used MineTwin to create a detailed simulation model of coal mine operations that was used to answer the following questions:
• How many dozers, excavators, and trucks are required to fulfill the plan?
• Is a buffer of ore needed in front of the conveyor? If so, what should its size be?
Period: July 2021 – October 2021
Industry sector: Mining
Client / Partner: One of coal mining companies/ Tomahee, Minfo
| Project objective |
- Determining constraints and equipment fleet configuration for one of the biggest open cast coal mines in Southern Africa
|
|
Our scope of work
|
- Definition of the problem on a series of off-site sessions with the mine’s personnel and implementation partner
- Creating the simulation model in MineTwin by configuring it and programming the client-specific coordination logic
- Validation the model to make sure it correctly captures volumes, speeds and mining rates
- Performing experimentation with the model to obtain the numeric results addressing the business challenges
|
|
System inputs
|
- Geometric and mining-geological features of mines
- Schedules, technological operations execution order and duration
- Technical characteristics and limitations of equipment and transport
|
|
Structure elements of the system
|
- Input data file of scenario in MS Excel format
- Simulation model on the MineTwin platform
|
|
System outputs
|
- Coal mining volume for each scenario
- Utilization of equipment types
- Achievable mining volumes for every size of buffer in front of conveyor transportation system
- Number of excavators, dozers and trucks required to reliably meet the mining plan
