Creating A Block Model - 2009 - MineSight

Where Do We Want to Go

•We want to create a 3D block model that contains the ore grades for our deposit

•To get this we will

–Create a file 15 (a file for a block model)

–Create a file 13 (a file for a gridded representation of the surface)

–Use our topo surface to create a grid of surface block elevations from our topo

–Create a Model View so I can see my Block Model as it comes together

–Use the gridded surface to code blocks above the surface to be air

–Use interpolation routines to project block ore grades from our drill hole data.

Importing Drill Hole Data Into Minesight

Next Thing I Need to Do is Import my drill hole data

lCommon things we know about drill holes

¡We know the location of the collar and we know the depth

lMineSight® looks for this in a collar data file

•Can use comma or space delimited so most work

¡We often do down-hole surveys to determine orientation of the hole

lMineSight® looks for azimuth and dip data over various intervals in a survey data file

¡We hopefully assayed samples from our drill holes at various intervals

lMineSight® looks for an assay file

Introduction to Minesight - topo surfaces

Where Do You Start With a Project

lProbably have a set of topographic maps

¡Probably autocad digitized and therefore importable to MineSight®

lProbably have collections of drill hole data

¡Again we’ll assume in computer form

Sequencing Mining Operations with MineSight

Maximizing Returns

lNPV is usually increased by bringing more early earnings and delaying expenses

¡Sequencing pits for high grade ore with lower stripping ratios tends to do this

¡We Need A Method of Finding the Best Grade Ore to Mine First

BLASTING IN SURFACE EXCAVATION

 Any blast optimisation programme calls for a clear understanding of the effects of principal blast parameters and their careful application.

The degree of fragmentation of rock depends on:
