SHORT COURSES
The temporary control of groundwater is a critical
aspect of deep shaft sinking. Ground freezing, which
also eliminates the need for shoring or internal bracing,
has proven highly effective in allowing safe excavation
within the surrounding frozen soil matrix and can
readily be accomplished in even the most difficult
subsurface conditions and at great depths. At times
ground freezing is be the only viable option. Although
ground freezing has been practiced for well over 100
years, this technology, and its advantages, is not well
understood outside of a narrow specialty area. This
course will provide industry professionals with a greater
knowledge of this versatile and valuable technology,
and the benefits of applying it to future projects.

Mine Water Balance 101
Member: $395 • Nonmember: $495
Student Member: $250
Many of the challenges faced by mining companies
involve water. This workshop will focus on water
balance studies and water balance modeling as a tool
for managing water quantity and (to a lesser extent)
quality at mine and processing sites. The course will
cover the following topics:
• What is a water balance and why is it important?
• What could a water balance be used for?
• Defining the water balance objectives
• Selecting water balance methodology and models
• Collecting and evaluating the water balance input
data
• Developing and calibrating the model
• Addressing water quality aspects
• Generating data for reporting requirements
(sustainability, closure, permitting)
• Using the water balance for decision making
A number of examples will be presented with the
objective to cover a range of site conditions and
project challenges. The use of different models will
be demonstrated for achieving optimal results. The
examples will also illustrate the use of the water
balance model for decision making. Participants
should bring their water balance issues/challenges; we
will choose one issue (more if time permits) during
the panel discussion at the end of the day to discuss /
develop a strategy to address the water balance.
This short course is targeted at participants who:
• Have or anticipate having water challenges at their
site.
• Want to optimize their current water management
practices.
• Want to understand how to approach and structure
a water balance study.
• Want to understand the current trends and best
practices for water balance modeling.
• Are curious about water balance modeling and how
to make sure models are calibrated and accurate.

Overview:
This short course will provide an overview of water
balance studies for mine and processing facility sites,
what they are, why they are important, and how to
interpret and use the results.
