The document summarizes a 3D solid volumetric model of the polyhalite resource at the Boulby Mine that was created by the author during an internship. Key points: - The model was created using borehole data from across the mine site to define the different lithologies like polyhalite and anhydrite layers in 3D. - Software like Datamine Studio was used to link borehole sections into a seamless 3D volume model of the various rock layers. - The completed model can be used for tasks like forecasting resource tonnages and grades, optimizing mine planning, and mine scheduling.

3. 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

4. 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

5.  Lithologies to be modelled:
• Fordon Anhydrite
• P3 (main bed) Polyhalite
• P2 (banded) Polyhalite
• P1 Polyhalite
• Z2 Anhydrite (the cap of the polyhalite sequence)

7. 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)

8. WORK FLOW IN PRACTICE
Array of drill
holes
Choose drill hole, eg. P001

9. W
P2 Poly
P1 Poly

10. MULTIPLE P3 PINCH
P017

11. Seismics Draped over Model

12. 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
