MassFlow mineblock format specification

A MassFlow ASCII-format, tab-delimited mineblock file has with the following specifications:

Line 1 - Comment. This line is ignored

Line 2 - These are the table headers. The first 20 columns are mandatory and must go in the following order:

Easting, Northing, Elevation, CavePeriod, CavePeriodDyn, BlockID, SolidsDens, InSituPor, MaxPor, FricAngle, MeanDia, MeanDiaDyn, PriFragA, PriFragB, TenStrA, TenStrB, UCS, PercK1, PercK2, PercVMR.

See Block Model for the meaning of these parameters. The exact text string used to describe each column is not important.

From column 21, extra columns with information about mine block ore grades can be added. There is no limit to the number of extra columns that can be added. Information in these columns is available as labels in the mineblock plot item and through the FISH functions massflow.mineblock.ore.name and massflow.mineblock.ore.value.

Line 3 - This line is ignored

Line 4 onwards - Actual values for each of the column defined in Line 2

The code block below shows a portion of a MassFlow drawbell file. This example has 3 extra columns after the first 20 mandatory columns, for a total of 23 columns.
