Pertinent InformationPertinent Information
WHERE: On the 9745 L in #5 remuck.
WHEN: April 14th, 2011 on night shift at 11:20 pm.
EQUIPMENT: Sandvik LH 514 8 yard scoop.
PEOPLE INVOLVED: Geologist/Scoop Operator.
WHAT HAPPENED?WHAT HAPPENED?
The scoop operator was re-mucking on the 9745 L from #5 re-muck to #7 re-muck; there was also another scoop re-mucking from #3 re-muck to #6 re-muck and 30 ton trucks were also being loaded at the #5 re-muck at intermittent times.
The geologist had been sampling in a few different headings within the 9745 L and once completed decided to leave the level.
WHAT HAPPENED?WHAT HAPPENED? The geologist then realized that he had
forgotten to take muck samples out of the #5 re-muck; so he decided to return to the #5 re-muck and collect the samples that he needed.
While he was taking his samples at the #5 re-muck the two scoops returned one scoop following the other; where one scoop continued past the #5 re-muck and proceeded to the #3 re-muck and the other scoop proceeded to slowly enter the #5 re-muck.
WHAT HAPPENED?WHAT HAPPENED? The operator noticed that the UPC geology
buggy was still parked just before the entrance to the #5 re-muck where there is a large hump on the floor in the ramp, but assumed that the geologist was in a different area of the mine.
The geologist noticed that the scoop was entering the re-muck; so he waited for the scoop to come to a complete stop.
He then noticed that the scoop was not going to stop; so he turned to attempt to climb the muck pile, but the muck was undermined from under his feet by the scoop consequently causing the geologist to fall and roll onto his back in the 8 yard scoop bucket.
WHAT HAPPENED?WHAT HAPPENED? The geologist then began to shake his
head from side to side flashing his cap lamp light at the back (ceiling) of the re-muck; which is when the scoop operator noticed that there may be someone in the re-muck, he stopped the scoop immediately and proceeded to verify if in fact there was someone in the re-muck and realized that the geologist was in the 8 yard scoop bucket.

Scoop #1
IMMEDIATE/DIRECT CAUSES: Failure to warn, Failure to secure/make
safe, improper placement: The geologist did not communicate to
the scoop operator that he would be working in #5 re-muck.
There were not any barricades in place to warn other personnel of someone working in the #5 re-muck.
The geologist put himself in harms way by staying in front of the scoop as entered the re-muck.
IMMEDIATE/DIRECT CAUSES: The scoop operator did not stop when he
noticed the geology buggy parked just before the entrance of the #5 re-muck.
Both the geologist and the operator were not in possession of a two-way radio.
There was a lack a planning in regards to the area being congested with multiple pieces of equipment working that immediate area.
BASIC/UNDERLYING CAUSES: The geologist exercised poor judgment by
not communicating with the scoop operator that he would be in #5 re-muck sampling.
The scoop operator exercised poor judgment by not stopping to check where the geologist was located once he noticed that the geology buggy was parked just before the entrance of #5 re-muck.
Geologist was not in possession of a two-way radio and all underground equipment is not equipped with base unit radios.
Jumbo operators were off line and grade when they were driving the 9745L ramp.
BASIC/UNDERLYING CAUSES: Signage, barricade, flashing light program
for service type employees not in place. Lack of work planning in regards to
congested work areas. Re-muck located on the blind side of the
equipment. Workplace entry communication program
not in place. Sandvik LH 514 Scoop design is in
question due to the operator blind spots while in operation.
RECOMMENDATIONS: Order and install base unit radios for
all underground equipment. Review and update geology sampling
procedure (include flashing beacon, barricade in a bag, reflective poles).
Formalize the mucking procedure. Review the mine design criteria for
re-muck locations and have the large hump on the ramp approaching the entrance removed.
Review with the jumbo operators the importance of drilling on line and grade.
Formalize a pedestrian travel procedure.
Formalize a communications policy for entering an active heading.
Change the buggy whips for the upc geology and survey buggys from 3 foot to 6 foot.
Discuss with Sandvik the possibilities of making changes to the design criteria on the LH514 Scoop.
