Automatic change propagation in an area-based open pit mine designer

1. A method for automatic change propagation in an area-based open pit mine design, said method comprising:

receiving, at a computer system, an open pit mine design, the open pit mine design having an associated mining timeline;

receiving, at the computer system, a user parametric input denoting an additional area to be incorporated into the open pit mine design;

automatically propagating, at the computer system, the additional area into the open pit mine design to generate a modified open pit mine design;

receiving, at the computer system, a user parametric input denoting an area to be erased from the open pit mine design;

automatically propagating, at the computer system, the area to be erased out of the open pit mine design to generate the modified open pit mine design;

automatically performing a compliance requirement review of said modified open pit mine design to ensure the modified open pit mine design does not have a violation of any constraints provided by a user-specified safety parameter;

generating an annotation field related to the modified open pit mine design, wherein the annotation field includes:

an environmental or geological reasoning for the additional area;

a monetary metric to illustrate a value of mining the additional area; and

a timeline change in the associated mining timeline for the additional area; and

automatically propagating, at the computer system, the annotation field into the modified open pit mine design.

2. The method of claim 1 further comprising:

comparing the user parametric input denoting the additional area to be incorporated into the open pit mine design with a present area of the open pit mine design; and

automatically limiting the additional area to areas that are not part of the present area of the open pit mine design.

3. The method of claim 1 further comprising:

receiving the user parametric input for a deepest layer of the additional area to be incorporated; and

automatically propagating the additional area from the deepest layer of the additional area to a top elevation.

4. The method of claim 1 further comprising:

receiving the user parametric input for a surface layer of the additional area to be incorporated; and

automatically propagating the additional area from the surface layer to a deepest layer.

5. The method of claim 1 further comprising:

receiving the user parametric input for a selected depth layer of the additional area to be incorporated; and

automatically propagating the additional area in both a shallow and a deeper direction from the selected depth layer.

6. The method of claim 1 further comprising:

evaluating the modified open pit mine design against design objective metrics selected from the group consisting of: a minimized amount of waste to be removed, a time frame, a maximization of ore obtained and a mine machinery availability.

7. A non-transitory computer readable medium comprising computer executable instructions that, when executed by a processor, cause the processor to perform operations comprising:

receiving, at a computer system, an open pit mine design, the open pit mine design having an associated mining timeline;

receiving, at the computer system, a user parametric input denoting an additional area to be incorporated into the open pit mine design;

automatically propagating, at the computer system, the additional area into the open pit mine design to generate a modified open pit mine design;

receiving, at the computer system, a user parametric input denoting an area to be erased from the open pit mine design;

automatically propagating, at the computer system, the area to be erased out of the open pit mine design to generate the modified open pit mine design;

automatically performing a compliance requirement review of said modified open pit mine design to ensure the modified open pit mine design does not have a violation of any constraints provided by a user-specified safety parameter;

generating an annotation field related to the modified open pit mine design, wherein the annotation field includes:

an environmental or geological reasoning for the additional area;

a monetary metric to illustrate a value of mining the additional area; and

a timeline change in the associated mining timeline for the additional area; and

automatically propagating, at the computer system, the annotation field into the modified open pit mine design.

8. The non-transitory computer readable medium of claim 7 , further comprising instructions that cause the processor to perform operations comprising:

receiving a user parametric input of a deleted area indicating a portion of area to be removed from the open pit mine design; and

automatically propagating the deleted area through the open pit mine design to generate a further modified open pit mine design.

9. The non-transitory computer readable medium of claim 7 , further comprising instructions that cause the processor to perform operations comprising:

automatically evaluating the open pit mine design against design objective metrics selected from the group consisting of: a minimized amount of waste to be removed, a time frame, a maximization of ore obtained and a mine machinery availability.

10. The non-transitory computer readable medium of claim 7 , further comprising instructions that cause the processor to perform operations comprising:

automatically developing the open pit mine design from the group consisting of: down from the user parametric input, up from the user parametric input and both down and up from the user parametric input.
