Abstract

A rock analysing unit reads data from instrumentation that measures the rock surface and bore and produces a three dimensional image to allow an operator to identify information about bore holes (32, figure 3) drilled in a rock bench. The image preferably shows if the bore holes are too close to the rock face such that damage to property or persons might occur after a destination of charge is placed therein. The image may include concentric circles placed around a bore hole, wherein the circles change colour if the distance between the hole and the edge of the rock is too short. The image may show the floor region (33) based on the depth and angle of the bore holes and may also display a cone (figure 4) for checking the alignment of the bore holes.

Description

1. Summary of the invention

Brief description of the invention

I) The invention is a method of getting and analysing rock drilling data and presenting the results in a three dimensional image that clearly shows the position of the drill holes and changes colour and or appearance to warn if the drill holes are in the wrong position, shape or depth before placing charges into the drill holes.

2) The system works as Ibilows: 3) A rock bench as shown in Figure 1 may have many drill holes. The rock surface and the bore are measured with instrumentation which then either stores data or sends it down a communication port to a laptop or PC as shown in Figure 2.

The proprietary software in the laptop or PC then reads the data and converts it into a 3D image as shown in Figure 2. Block 21 is Instrument Data Input. Block 22 is were the processing of the 3D Image occurs and Block 23 is the 3D Image Output displayed on the screen.

It may be seen by Figure I that each bore also referred to as drill holes X Y and Z are a certain distance away from the edge of the rock marked XX. If this distance is too short the areas around the concentric circles change colour. Certain colours such as red indicate that it may be dangerous to firing a change in the hole. Doing so may cause pieces of rock to fly out up to 1 kilometre thereby causing injury to animals or people or damage to property. If any red, however small it is means a charge should not be put in the hole which is causing the red to appear.

Some bore holes Items 32 are also drilled with a curve from the Rock Bench Item 31.

This curve or hole angle is also taken into account in the system as shown in Figure 3.

Another aspect is the depth of the holt This should normally be such as to provide a floor [tern 33 after the rock has been blasted. The floor is shown also on the three dimensional image as drawn in Figure 3.

There is also a cone or other suitable shape drawn on the 3D image usually in orange.

These are shown in Diagram 4 the cones are marked as XX and 1012 and the Rock Bench Item 41. Ifthe bore hole is outside this shape then the operator can see by the * position of the cone compared to where holes should be. Also for the charges to be * * efficient then another colour, say yellow, is shown over the rock bench, and this should be as large as possible otherwise rock may be left after the charges are fired.

Percentage burden values are entered in to the system which adjust the extent of the various colours in the 3D image, that is to say these values are decided on depending on * rock face and charge conditions. * . * S.. * *

Claims

Claims I. A rock analysing unit that reads data from surveying equipment, analyses the data and produces a three dimensional image that the operator can easily idenülSl infonnation about the bore holes drilled in the rock bench.
2. A rock analysing unit according to claim Il, in which the three dimensional image shows if the bore holes are too near or otherwise in proximity to the rock thce as to cause damage to property or persons after a destination of a charge placed therein.
3. A rock analysing unit according to claim I, in which in which the three dimensional image shows the likely amount of rock that will be removed by highlighting the region which would be removed after the charge has been fired.
4. A rock analysing unit according to claim 1, in which in which the three dimensional image shows the floor region based on the depth and angle of the bore holes.S. A rock analysing unit according to claim 1, in which in which the three dimensional image shows a cone that checks the alignment of the bore holes 6. A rock analysing unit according to claim I, in which in which the three dimensional image shows the bore holes themselves. 0***fl.fl * . * . a..... * . *0a * * . a. *
