Lynn Nelson,
President of WMEA, called the meeting to order at 8:07 a.m.
Lynn greeted
the attendees and welcomed all to Calgary. He alerted all to the need to
maintain registration information accurately in the WMEA files as some
individuals move around and do not keep the file info up to date.
Minutes get sent out at a cost exceeding $20.00 US, and some are being
returned as undeliverable. Forms are available on the registration table
to check and leave your correct address.
Lynn also
commented on the need to be a flag bearer on behalf of WMEA, each to
his/her own organization. Members need to be making a report of the
information they received and the value their company has gained through
attendance at WMEA. In these days of austerity management only
worthwhile events are being supported. We believe WMEA is one of those
worthwhile organizations and needs the support of all of mining. But,
mine management will not know of the benefits they are gaining through
supporting attendance at these functions, unless you tell them. We will
include a copy of the meeting summary on the website shortly after the
meeting, so you might pass it on to your management. Lynn complimented
of Syncrude Canada Ltd. for the quality work he has done
on the website.
Lynn
discussed the continued need for Steering Committee members, requesting
the need for members to take an active role in their organization.

Web Site Update
Wayne Parsons - Syncrude Canada Ltd.
Wayne brought the web site to us online. Demonstrating the contents of
the site, how it works, what information it contains, how to get
information from the website, how to update your company information.
Links are available for Mining companies as well as for vendors and
other related organizations. He demonstrated the ability to ask
questions (Ask WMEA) or provide answers to those questions that have
been asked. He intends the web site to be an interactive one – so
please use it. There is a guest book
for visitors to register in. Wayne or any of the executive committee can be contacted
through the web site.

Variable Frequency Drive Cable
Dan Mainstruck - General
Cable
This presentation builds on the recommendations from the IEEE study
which was done by Bentley & Link in 1996. It discusses the problems
generated by harmonics within a cable system. Ground currents, common
mode currents and reflected waves can cause problems ranging from
destruction of windings to unwanted machine motion or voltage inducement
caused by cross-talk and related noise. This presentation describes the
problems typical in modern VFD systems and recommends a cable
manufactured to the specifications of Bentley & Link 1996, which
will not clean up the power system, but will contain the maladies to
that specific system.

Partial Discharge Theory
and Applications to Electrical Equipment
Cal Patterson – Cutler-Hammer
This expands the predictive maintenance envelope a little
more. Cal presents a method of electrical failure monitoring of rotating
equipment using embedded RTD’s as a window to look inside rotating
apparatus and measure the degree of electrical leakage occurring. He
also describes Vibracoustic Analysis of transformers pioneered by Victor
Sokalaw of Russia, using accelerometers to analyze transformer
condition. Rotating apparatus, motor control center and electrical buss
monitoring will soon be available with continuous online monitoring
capability allowing another method of providing on line trending of
electrical apparatus condition.

3D GPS Monitoring and Positioning
Jim Gray - Aquila Mining Systems
A Montreal, Canada based company, Aquila was formed in 1992 at the
request of the Canadian mining industry and is a member of an alliance
of companies including Trimble, Caterpillar, Aquila and Mincom. Aquila
has specialized in blast hole drill technology providing real-time data logging
and online feedback to the
drill, thus providing blast hole loading equipment with the exact
explosive requirements. The drill position is monitored and directed
through GPS positioning and online downloading of positioning data to a
common data buss. This has provided extremely accurate blast hole
locating without the requirement to survey. This proven technology is
now being applied to draglines, eliminating the need to survey in
dragline cut positions and reject feed zones etc. The end result will be
similar to that provided to blast hole drills, the dragline will supply
information on the type of digging which will relate to, the type of
feed, where it is located and where it has been placed while logging the
production data onto the same data buss. In turn the dragline will
receive cut plan data which can be selected by the operator within
limits given. Bridger Coal will be the first to experience this system
on board their machines.

MSHA Noise Regulation Update
Glen Hood – TXU Mining
Since MSHA in the USA first introduced the revised noise
regulations last year, (September 13, 2000) there has been a good deal
of confusion throughout the US Mining industry as to what this will mean
to Miners. OSHA has taken the approach that no one actually wears
hearing protection, so has assigned noise level values at which working
time must be restricted. This is regardless of the value of the hearing
protection that can or must be worn. That value is 115 decibels which
will be enforced at 117 decibels never exceed value with a maximum
duration in a 12 hour period of 15 minutes. Most jurisdictions within
Canada while tightening enforcement, still consider hearing protection
effective and do not assign a maximum value that can occur while workers are present. Glen reported on a meeting
led by Bucyrus International at Milwaukee involving interested members of the mining community. Jerry Endres and
Glen performed testing on TXU draglines and presented that data, showing
problem areas on each machine type. This interesting data and topic
created a good deal of floor discussion.

Driverless Trucks – Update on Newest Technology
Les Zoschke – Modular Mining
Modular
Mining working with Komatzu has developed a very repeatable and reliable
system of operating a haul truck fleet sans the operator. Les Zoschke
walked us through a pictorial as well as technical overview of the 4
truck fleet they have operating at a mine in Australia. The trucks are
provided with GPS as well as inertial guidance systems operating in
tandem, providing a guidance system that is so repeatable the trucks
always follow the exact same tire track, braking and accelerating at the
exact same point. Whole truck monitoring is provided as is radar and
other sensory systems which protect workers and other equipment which
ventures onto the haul road. Modular is so satisfied with the current
state of their technology that “babysitter operators” are no longer
used on the trucks. Les demonstrated the haul dump characteristics and
single backup loading capability. He stated that double backup loading
and highwall dumping is something yet in the future. This is a
technology still in the making.

Update on Alberta’s Regulatory Review Process and Its Impact on Mining
Don Hindy –Alberta Mines Health & Safety Program Coordinator
Some
changes have been occurring since Don last met with WMEA in 1999. There
is a mandatory 5 year review process for regulatory issues, that began
in 1999. Existing Workplace Health & Safety regulations include:
Mines Safety Regulation, General Safety Regulation, Chemical Hazards
Regulation, Explosives Regulation, Noise Regulation, First Aid
Regulation, and Ventilation Regulation. Once the review and
consolidation is completed there will be one or 2 volumes of one book
rather than the seven which now exist. This new regulation should be
adopted into law by approximately Oct. 31/01. To coincide with the new
regulations, all existing regulations will be appealed – including the
existing Mines Safety Regulation. The new CSA Standard M421-00 Use of
Electricity in Mines will be adopted into law also. There is new
“Working Alone” regulations that will affect mining. Changes will
occur to provide privacy for First Aid records, a logbook can not be
left out for all to sign and see. The government is preparing slide
presentations that will be handed out so companies may easily provide
presentations to their employees. Don also presented some slides showing
how the LTA rate appears to have bottomed out showing that current
programs will not lower injury rate any further; they will be looking at
the workplace a little more to ensure that existing and new standards
are being applied. They are also looking for new methods of lowering the
workplace injury rate.

Identified Electrical Issues
from Mines Inspections in Alberta
Ron King – Alberta Mines Electrical Inspector
Ron
concentrated most of his time on substation grounding and problems with
the coupling of equipment grounds and station grounds together. There
are problems, especially in tarsand, associated with establishing the
voltage rise levels, stated in Table 52 of
IEEE No. 80, which is required by code in Canada for step and
touch potentials in substations. Ron presented some computer
representations of the problem. He also reiterated Don Hindy’s comment
about the adoption of the new M421-00 into law this fall, so look it
over and send him or Don any concerns you might have.
