RECBLKST is used to compare the tonnes and grades of model cells within outlines between two surfaces. Subcell divisions are created in the input block model by the process and written to the output model. The output model can be used to view the volume within the outlines between the two surfaces. Optionally an overall bounding perimeter can be supplied.

An example of the inputs and outputs is shown in the following image:

Yes

Wireframe triangle

MINEDPT

Triangle Point File of the second or mined surface

The wireframe point file of the second or mined surface

Input

Yes

MODELOUT

Output

Yes

Block Model


Output reconciliation model. This contains subcells between the first (designed) and second (mined) surface with flags defining the planned cells.

BLOCKRES

Output

Yes

Results

Output results file containing tonnes and grades within each mining block outline.

BLOCKRES

Output

Yes

Results

Output results file containing tonnes and grades for categories of PLANNED and MINED. The categories, with value of CODE from 1 to 5, are as follows:

CODE=1, SOURCE=PLANNED:

The total amount of PLANNED material in the model: the quantity of material in the volume below the first surface that is described by the mining block outlines.

CODE=2, SOURCE=MINED:

The total amount of MINED material in the model: the amount of material between the two surfaces.

CODE=3, SOURCE=PLANNED and MINED:

The total amount of PLANNED and MINED material in the model: the amount of material between the two surfaces and contained within the mining blocks.

CODE=4, SOURCE=PLANNED Only:

The total amount of PLANNED and NOT MINED material in the model: the amount of material in the mining blocks that is not between the surfaces.

CODE=5, SOURCE=MINED Only:

The total amount of MINED and NOT PLANNED material in the model: the amount of material between the surfaces that is not in the mining blocks.

Values

DPLUS


The projection distance measured in the increasing vertical direction to be used to create volumes from the input mining outlines. This is used if there is no DPLUS field in the mining outlines file.

No

Undefined

Undefined

Undefined

DMINUS

The projection distance measured in the decreasing vertical direction to be used to create volumes from the input mining outlines. This is used if there is no DPLUS field in the mining outlines file.

No

Undefined

Undefined

Undefined

XSUBCELL

Cell division in X direction for splitting against perimeters (1). Max 20. This is the same as the control in the PERFIL process. A value of 1 will generate no splitting. A higher number will generate subcells which more closely represent the perimeter shape but there will be more of them.

No

Undefined

YSUBCELL

Cell division in X direction for splitting against perimeters (1). Max 20. This is the same as the control in the PERFIL process. A value of 1 will generate no splitting. A higher number will generate subcells which more closely represent the perimeter shape but there will be more of them.

ZSUBCELL

Cell division in X direction for splitting against perimeters (1). Max 20. This is the same as the control in the PERFIL process. A value of 1 will generate no splitting. A higher number will generate subcells which more closely represent the perimeter shape but there will be more of them.

SPLITS

Maximum amount of splitting to be allowed when spitting cells with topography. The default value is 3.

=0 : no splitting: parent cell.

=1 : 1 split: 2 x 2 subcells.

=2 : 2 splits: 4 x 4 subcells.

=3 : 3 splits: 8 x 8 subcells.

FACTOR

Scaling factor to adjust the units of the Volume and Tonnage in the output files. Volume and Tonnage are divided by this factor. This is the same parameter as used in the TONGRAD process

No

SETABSNT

Set to 1 to allow TONGRAD to internally reset absent grade and Density values. If this is used, absent grade values are set to their default values. If the default value is absent grade values are set to zero. If Density values are absent the default DENSITY parameter value is used.
