Description
3D Simulator uses high-tech three-dimensional technology. This is crucial for the virtual training of shotcrete operators. The working environment is perceived by the trainees in three dimensions. Thus, operators are able to estimate the spraying angle and the distance from the nozzle to the surface of the rock. Training in a 3D environment increases the realism of the simulation. The successful simulation relies on the programmed patterns based on concrete modelling of adhesion and detachment.
The 3D Simulator is a tool for training and upgrading the skills of shotcrete operators and specialists, and is used by tunnelling and mining companies, as well as other shotcrete users. The simulator includes a standardised training package that allows beginners in shotcrete spraying to reach a good level of training before entering the production process. The simulator also allows experienced operators to improve their qualifications. More than anything, the simulator offers the acquisition of practical skills outside the working environment in a peaceful, friendly and safe working environment without losses and waste accompanying sprayed concrete. Furthermore, 3D Simulator provides a more efficient training, thanks to the possibility of obtaining real-time information for an angle of the nozzle and the distance from surfaces, the rebound and excess amount, the concrete used during the session and the dropouts - important parameters determining the quality and value of the final product. These parameters can not be measured in an active work environment. Typically, new operators training on-site, using remote-controlled robots takes up to five hours a week. The simulator allows the process of reaching a good level of qualification to accelerate, increasing training time to 40 hours per week.
Training program
The program is adapted to meet the needs of the participants in the shotcrete application. It is divided into two main blocks:
- Specialised training and qualification of operators of robots for applying sprayed concrete (shotcrete).
- Specialized training of management personnel - managers of shift, technicians, and others.
Each of the blocks is divided into two modules:
- Theoretical, for two days, gives insight into the sprayed concrete and its specifics, function, requirements, qualitative control and testing. Review of recent advances in shotcrete technology. The theoretical part ends with a test/quiz.
- Practical, based on 3D Simulator, for 5 days (only for operators), in which they are asked to solve different problems and situations, by controlling the robot's boom, using a remote, in order to optimise the layers thickness, the rebound, the accelerator dosage, preventing detachment and sprayed concrete dropouts and so on. The assignments include spraying behind a corner or in a specific area, minimum - maximum thickness, time limit and others.
The course ends with a practical examination, the results of which are evaluated by the 3D Simulator.
