Internship presentation

A 3D SOLID VOLUMETRIC

MODEL OF POLYHALITE

RESOURCE BOULBY MINE

PREPARED BY ANDREW MOYLE

4TH YEAR GEOLOGY STUDENT – ABERDEEN UNIVERSITY

9TH SEPTEMBER 2016

PROJECT INTRODUCTION

Requirement:

Collation of all data relating the

development and exploration of the poly

halite resource at ICL

Defined Task:

Production of a 3D Solid volumetric model

of the polyhalite utilizing the latest

horizontal and vertical drill data to define

lithologies

TASK

The 3D Model

• Insertion of grade information

• Forward planning of production

• Development of mining strategy

Modelling

• -Combination of MS Access databases

& “Datamine Studio” RM/EM

• -use of borehole info to generate lithological

sections

• -link these into a seamless volume

Lithologies to be modelled:

• Fordon Anhydrite

• P3 (main bed) Polyhalite

• P2 (banded) Polyhalite

• P1 Polyhalite

• Z2 Anhydrite (the cap of the polyhalite sequence)

BUILDING THE 3D MODEL

Work flow:

Import data logged,

geo-referenced and

drawn in Autocad

Change data to

required properties

(Units in this case)

Draw sections of

surface along the line

of each borehole

Link drawn sections

together with

wireframes

Check and validate

wireframe as

lithologically accurate

Repeat for next

lithology

Input a back pin

(identified from drill point

and logging elevation)

WORK FLOW IN PRACTICE

Array of drill

holes

Choose drill hole, eg. P001

W

P2 Poly

P1 Poly

MULTIPLE P3 PINCH

P017

Seismics Draped over Model

HOW THE MODEL AND SOFTWARE CAN BE

USED

Forecast future tonnes and grade

Optimized mine planning

Powerful Scheduling tool

Part of a universal model = different data input
