This command is used to report data value
statistics on each grid or overall statistics within the block
model. The user is prompted to select one of the reporting
method, Report by Attribute/Quality, Report by Grade Parameters or
Report by Levels/Grids. The reports are generated using the Report
Formatter. There is an option to select an inclusion perimeter to
limit the report to an area. Otherwise the report will cover the
whole block model.
The Report By Attribute/Quality reports statistics
for all the samples of each attribute in the block model. Here's an
example:
Name Samples Min Value Max Value Avg Value Variance Std Dev
SIO2 143820 3.07 71.12 26.88 61.25 7.83
CAO 143820 4.03 53.31 34.78 47.13 6.86
The Report By Levels/Grids reports statistics for each attribute grid at each level in the block model. The attribute names in the report have the level sequence number as a suffix. The grid levels are numbered from 1 at the bottom and going up. Besides the statistics on the attribute values, the report also has statistics on the elevation and depth for each level. Here's an example portion of a report:
Name Samples Min Value Max Value Average Value Std Dev Avg Top Z Avg Bot Z Avg Depth
CAO[1] 1410 21.42 43.78 35.67 3.91 47.93 47.43 101.67
CAO[2] 1410 20.96 43.71 35.67 3.99 49.92 48.93 100.17
CAO[3] 1410 20.59 43.82 35.67 4.06 50.92 49.92 99.18
CAO[4] 1410 20.37 43.88 35.68 4.14 51.92 50.92 98.18
For Report By Grade Parameters the program prompts for a Grade
Parameter File (gpf) and reports the number of blocks for each
grade along with the min, max and average values of the attributes
for each grade. With this report, besides using an inclusion
perimeter to limit the blocks to report, you can also use a solid
model (MDL) or top or bottom surface grids.
