3 DAYS COURSE ON PRACTICAL GEOSTATISTICS IN MINING
 
Venue: Jayakarta Hotel Bandung,
December 14 – 16, 2009

Introduction
Since introduced by D. Krige (1955) and G. Matheron (1960), geostatistics have
been widely used in mining industry for resource and reserve estimation.
Geostatistical analysis provides a powerful tool for enhancing the prediction
and decision making capabilities of mine planners and geologists.
 
The experimental semivariogram provides the only measure of whether a deposit,
or part of a deposit, is best analyzed using geostatistical methods or whether
classical statistics would suffice.
 
Geostatistics provides the best possible weighting for samples used in reserve
estimation so as to produce the lowest possible error of estimation.
The traditional reserve estimation methods give reasonably good predictions of
the insitu tonnage, but they are not accurate enough for predicting grade or
quality variables on a short term basis, nor do they give any estimate of how
accurate their predictions are.
 
This 3 days course will share the application of geostatistics in practical
aspect of mining mainly in the case of spatial characterization and estimation
of coal quality, lateritic nickel, base metal, and tin placer.
 
Objectives
The objectives of this course are:


To give understanding about the principle of geostatistical methods in mining
application and its superior over traditional reserve estimation methods.

To give knowledge about the rule of thumb on variogram construction and fitting
model as the variogram modelling is the most critical part in geostatistical
estimation.

To give practical skills on statistical data analysis, variogram modeling,
reserve estimation and classification based on geostatistical method.
 
Who Should Attend
Mine engineers, geophysicists, geologist, geosciences, and everybody or
professional who want better understanding and to broaden the knowledge from the
course subjects.

The principal Facilitator
Dr. Mohamad Nur Heriawan whose educational background are Bachelor of
Engineering in Mining Engineering (ITB, 1998), Master of Engineering in Applied
Geophysics (ITB, 2000), Postgraduate Diploma in Mine Geostatistics (Ecole des
Mines de Paris, France, 2003), and Doctor of Philosophy in Geostatistics and
Geomodeling (Kumamoto University, Japan, 2007). At present he is Assistant
