involving disabling of the ground monitor system during dragline boom
lowering. Respondents are following the recommendations documented in a letter
from a local MSHA inspector covering the Wyoming area. Most important to
maintain radio contact between individual at the substation and person
coordinating the activity at the dragline.
Motor & Control: said at one of the gas plants he visits, vendors are being
supplied with colored Nomex coveralls to distinguish them from employees. This
is done as a safety precaution so in an emergency, people that may not be
familiar with evacuation procedures can be easily identified and escorted to
ladders/platforms to rolling stock as a means to decrease fall
potential/injuries. Caterpiller is getting onboard with this through new
upgrade offerings for their equipment.
Phelps Dodge is
working closely with NIOSH in a number of areas. One of the current projects
involves developing collision avoidance systems for installation on
vehicles. Technology involves the use of radar and video cameras.
NIOSH, as an arm of the federal government and the engineering arm of MSHA,
carries a lot of weight when a company is using data collected in a joint
venture for backup on compliance issues.
In the case of
Phelps Dodge, NIOSH is providing most of the equipment being used for the
projects being carried on. The company participating doesn’t see a lot of
out of pocket expense.
that would like to investigate a possible joint project, the NIOSH contact
is Todd Ruff, 1-509-354-8053. Todd’s email is ‘firstname.lastname@example.org’

surrounding a transformer installation.

Gary Lozowski – National Carbon – Their Company went one
year without a lost time accident and gave all the employees a wristwatch
for their accomplishments.
Don Patterson – Drives and Controls Services – Noise
control – Talked about MSHA noise regulation and where that stands now. He
knew of one company that tried to install blankets between M-G Sets to control
the noise but that did not help much.
He also talked
about a mine that has a line painted in the shop to distinguish different
hearing protection areas.
has designed a small variable speed drive and a small motor that attaches to
the shaft of the hoist or drag drum to turn the drum without the – M-G sets
running – seems to work well and reduces the noise in the back of the machine
and can utilize the electricians better for brush inspection and for working
on the M-G Set.
Dallas McIntosh – Bucyrus Canada – He said that in Canada
they do not have the consistency that the US has with MSHA and would like to
see standardization in the Canadian mines if anyone has any ideas.
Curtis Peterson – Phelps Dodge – talked about different
clothing for protection – Such as flash coats – their company revisited this
issue and the technology has changed a lot – seems that there has been several
times this issue has come up. They saw problems with wearing big coats and one
employee fell because the coat was too bulky. He was wanting to know if anyone
has more information about this concern.
Mike Erisman – Cordero Rojo – Talked about their isolation
officers – they are responsible for lock-out tag-out – they are also
responsible to be sure that everyone is clear when unlocking equipment.
Don Patterson – Drives and Controls Services – They are
still developing and installing Data Acquisition Monitors for looking at the
machine functions from the office – XY’s, Currents, Voltages, Vibration
Information, also Video that scans an image and sends that to the office –
Also he said there is a company in Australia that is planning to link 36
Mike Erisman – Cordero Rojo – They upgraded their Marion
8750 machine with digital generator field drives - DCS installed them –
working out very well – seems to have smoothed out the swing motion.
Don Patterson – Drives and Controls Services – They are in
the process of upgrading a dragline with a digital armature drive for the
swing motion. This would be a high current drive and eliminates the swing
Curtis Peterson – Phelps Dodge – Installed a payload
estimation device on their shovel – DCS installed it – seems to be very
accurate – it weighs the material in the bucket – he says the accuracy is as
good or better than what DCS had promised. They are within 5% accurate.
Curtis Peterson – Phelps Dodge – talked about cameras on
the machines – wanted to know if other companies are using them. He said they
have one installed on one of their shovels that looks off the side of the
machine – they had an incident where a hauler operator was washing his windows
while the shovel operator did not know the hauler operator was out of the cab
but he saw him with the camera and did not dump – possibly avoiding an
Dallas McIntosh – Bucyrus Canada – They are installing
some cameras for some of their customers – may be the answer to a lot of
Dennis Isaacs – Northwestern Resources – use cameras on
bucketwheel system and also for boom lowering and raising.
Try to get someone from MSHA to explain the discrepancies
between the inspectors interpretations.
Collision avoidance systems. (Motion detectors, Cameras in
blind spots, Etc.)

concerning part 77.501- waiting on clarification from MSHA.
RAG incident. One
pickup pulling another. Welded clevis to bumper of first vehicle busted and
went through windshield of second pickup killing the driver.
Antelope coal 2300
incident with contract cleaner. Center pin grease line access hole had been
widened. Contract cleaner used an aluminum wrapped broom handle, attached to
vacuum hose, to clean came into contact with high voltage slip ring.
Contractor was injured but not killed.
Two incidents on
trucks rolling away from not following proper procedures. Operator was told
that truck was on fire. Operator jumped from the truck. No brakes were set.
Truck rolled backwards down a grade until it came to rest on its side. Rio
Tinto property, a truck rolled backwards, the bed of the first truck crushing
the cab of the one behind it. Killing the operator.

Lee Adams –
North American Coal – Sabine Mine
They moved PCR Room reset to the outside for operators.
PCR rooms are locked. They have a program where mine personnel can fill out
cause analysis sheets and submit them; then they have a monthly drawing for
a day off. Sabine rotates operation supervisors through Safety Department
Steve Casille – P&H Mine Pro – Mesa, Arizona
P&H is on a revitalized safety program, upper management is
setting the tone; asking personnel to rethink safety.
John Donahue – Electro Test
They work around hot gear a lot so they have work
procedures they follow and monthly safety meeting to discuss procedures.
Don Smales – Cortez Gold
Their company uses observation cards by employees to report
good and bad things they see – monthly reports on these long range is to get
employees to bring things to the attention of others.
Jon Vendela – Spring Creek Coal
He discussed KEC safety issues and ways to get everyone to
discuss safety when they see problems.
Mark Fuller – American Cable
Their company has given cable handling talks and made
videos of problems they see on site to help your company with safety.
Mark Fuller –
They have a new reflective strip they put into the
jacket, it works at night and has been in oil sands six to eight months and
Don Smales – Cortez Gold
He discussed new digital upgrade on 2800.
Lee Adams – Sabine Mine
They use VFD on 100HP well to stop start up dimming lights.
Clark – Barick Gold
Their new DCS Accu Weight system on shovels is doing well.
John Donahue – Electro Test
They can measure contact resistance while hot on up to 480
Volt systems that cannot be shut off.
Mark Fuller –
Discussed shovel feed like cables to VFD drives need to
be balanced, 3 grd 30, center pilot and insulated for spikes.
Lee Adams – Sabine Mine
Asked if anyone is doing RMS monitoring of machines with
digital drives? Sabine has a long run of trail cable to dragline and is
looking for a boost system to hold voltage up.
Jason Shaw – Luskar Mine
They are starting to look at hi frequency transformer
vibration acoustic analysis.
Brian Clark – Barrick Gold
They started program with P&H using IR and Vibration
monitoring on shovels to help Barrick with preventative troubleshooting.
Jon Vendela – Spring Creek Coal
Their goal is to reduce cable size and eliminate the back
injuries that occur with 500 MCM cable. They are testing a dragline soft start
system. This system is different in that it uses the existing motor and
generator field drives to run the sets up to sync speed and then close in the
sync starters. This should reduce the cable size from 500MCM to 4/0
constituting a weight reduction from 12 pounds to 6 pounds.
He also discussed the their new PLC on the 2300 shovel.
