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:

Files, Fields and Parameters

Input Files

Name	Description	I/O Status	Required	Type
MODELIN	Input model file for reconciliation.	Input	Yes	Block model
BLOCKS String file of mining outlines	Input string file containing mining outlines. These are projected up and down to define designed volumes. Each string must have all its points on the same elevation.	Input	Yes	String
PREVTR Triangle File of first or initial mining surface	The wireframe triangle file of the initial mining surface.	Input	Yes	Wireframe triangle
PREVPT Triangle Point File of first or initial mining surface	The wireframe point file of the initial mining surface.	Input	Yes	Wireframe points
MINEDTR Triangle File of the second or mined surface	The wireframe triangle file of the second or mined surface.	Input	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	Wireframe points
PERIMIN Optional String file to control the overall area of processing	If specified this optional file must contain at least one perimeter (e.g. a bounding pit perimeter) to control the area in which processing occurs.	Input	No	String

Output Files

Name	I/O Status	Required	Type	Description
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.

Fields

Name	Description	Source	Required	Type	Default
BLOCKID	The field name in the input BLOCKS outlines file that identifies individual mining blocks	BLOCKS	Yes	Any	Undefined
DPLUS	The (optional) field name in the input BLOCKS outlines file that specifies the amount of upwards projection of each mining block. The default field name is DPLUS, which will be used if it exists in the BLOCKS file If this is not specified the DPLUS parameter value is used	BLOCKS	No	Numeric	Undefined
DMINUS	The (optional) field name in the input BLOCKS outlines file that specifies the amount of downwards projection of each mining block. If this is not specified the DMINUS parameter value is used	BLOCKS	No	Numeric	Undefined
KEY1	A key field in the model file that is used to categorise results. For example this might be a rock type or zone identifier.	MODELIN	No	Any	Undefined
DENSITY	The Density field in the input block model.	MODELIN	No	Any	DENSITY
GRADE1-10	Grade fields in the input block model to be evaluated and included in the results.	MODELIN	No	Numeric	Undefined

Parameters

Name	Description	Required	Default	Range	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	1	1,20	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.	No	0	0, 1	0, 1
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.	No	0	0, 1	0, 1
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.	No	0	0, 1	0, 1
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	Undefined	Undefined	Undefined
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.	No	0	0, 1	0, 1
BENCH	Set to 1 to categorize the reserve comparisons by benches. =0 : Do not categorize by benches. =1 : Categorize the results by benches (as defined by the model ZINC default value).	No	0	0, 1	0, 1
