The Terrock Tools System consists of:
- Ground vibration and Airblast regression and contours.
A regression analysis of both ground vibration and air blast is an effective tool which is used to predict vibration levels over certain distances. The tool makes use of known levels recorded on monitors at certain distances to a blast which are plotted on a graph. A scaling analysis can then be conducted to obtain predicted levels at certain distances from the blast.
If blast parameters are known, these can be input into the contour tool which will reveal the distances to which certain vibration and air blast levels will occur. These contours can then be used to place over maps in order to analyse the levels that may occur at certain receptors surrounding the blast.
- Flyrock Modelling
The Flyrock Modelling tool is used to predict the maximum distance rock can be thrown from a blast. Blast parameters are input into the system to reveal the maximum distance and direction in which rock can be thrown from a particular blast. Safety factors are then put in place to provide minimum clearance distances that both equipment and personnel must be situated at the time of the blast.
- Blast Pattern design
Blast pattern design can be used to create a blast pattern with the input of a few basic parameters. The designed pattern can be used as a basis for which predictive modelling can occur. Tie-up patterns can also be added in order to conduct wavefront reinforcement analysis. These tools all provide the user with the ability to analyse the blast pattern to ensure they can conduct a safe blast within the work limits.
- Mathematical conversions
This simple tool can be used to provide a conversion from one form of unit another. It also provides a simple way to uncover unknown factors within the design parameters which can enhance the accuracy of the blast predictive modelling.
