Traffic Awareness and Collision Avoidance for Surface Mining
Equipment – A Case Study
T. Ruff 1 and T. Medinski 2 ; 1 SAFEmine Technology USA, Oakland,
CA and 2 Teck, Trail, BC, Canada
A trial of the SAFEmine Traffic Awareness and Collision Avoidance System was
conducted on surface mining equipment and light vehicles at Tecks Line Creek
Operation in 2012. The SAFEmine system determines vehicle location and
movement information using GPS, while peer-to-peer radios are used to communicate
this information to surrounding vehicles. The six-week trial was designed
to evaluate the effectiveness of SAFEmine for increasing operator situational
awareness and providing warnings of potential collisions. The trial was split into
two phases: a two-week OFF phase where alarm data was logged, but not presented
to operators to establish a baseline; and a four-week ON phase to determine
effectiveness, acceptance, and how operator behavior was affected by system
alarms. Parameters of interest were speeding, following too close, light
vehicle to heavy vehicle interactions and heavy vehicle to heavy vehicle interactions.
Performance criteria were based on several factors including GPS accuracy,
system reliability, effectiveness of intelligent alarming, operator acceptance, and
potential site safety improvement.
2:25 PM
Application of Borehole Logging and Probing Systems for Ground
Characterization in Mining Operations
A. Naeimipour 1 , X. Yu 2 and J. Rostami 1 ; 1 EME, Penn State
University, University Park, PA and 2 China University of Mining
and Technology, Beijing, China
Understanding the geological condition of surrounding rock in mines is the first
step in recognition of potential hazards and design of the appropriate ground
support system. Availability of the correct and sufficient information is the essential
tool to mitigate ground control problems, but there is often limited information
about the surrounding rock and the exploration borehole measures are few
and far in between. Typically no one is allowed to venture into unsupported
areas, thus the amount of information is naturally limited to mapping in the
bolted/supported areas and to the activities that can be performed in short period
of time. Meanwhile there have been vast advances in the area of ground characterization
using various probing devices that could be adopted for mapping of the
geological features and ground/roof/risk mapping. This paper will review the
geophysical logging methods and their application in mapping the roof strata and
ribs and will offer the most suitable methods and equipment for various applications.
The research underway to couple borehole logging with the development
of mapping while drilling approach will also be discussed.
2:45 PM
Operator Assist Technology for Advanced Dust & Noise Mitigation
and Obstacle Avoidance in Underground Mining
B. Thompson; Joy Global, Milwaukee, WI
Global regulations continue to drive change in the operating environment. Key
areas of focus center around dust, noise, and proximity detection. Joy has
recently tested and released new systems to assist operators in meeting or exceeding
these regulatory proposals. We will review testing, validation, and implementation
of these new technologies in pursuit of Zero Harm.
3:05 PM
Engineering The Health, Safety and Comfort of Dump
Truck Operators
S. Frimpong and N. Aouad; Mining and Nuclear Engineering,
Missouri University of Science and Technology, Rolla, MO
Dump truck operators are exposed to whole-body vibration (WBV) levels that exceed
the ISO 2631-1 Standards. The WBV level, measured by RMS acceleration
value, for operator comfort, and long-term health and safety is under 0.315 m/s2
by these standards. However, fundamental research by Frimpong and Aouad
(2009, 2012) and field experimental study by Kumar (1999) have shown that operators
are exposed to extreme WBV levels exposing them to injuries and musculoskeletal
diseases in the long term. This presentation will outline current research
to solve these problems.
3:25 PM
Behavior and Performance Analysis Using PreVail
A. Bhushan; Joy Global, Milwaukee, WI
PreVail, Joy Globals Remote Health Monitoring (RHM) technology collects and
screens large amounts of machines health and performance data on P&H electric
shovels. The technology has proven to greatly reduce the amount of time required
to determine root cause of traditionally complex and time-consuming
electrical drive and control systems issues for faster resolution and return to productive
operation. P&H PreVail RHM helps to optimize machine performance
which in turn lead to production enhancements, maintenance optimization, and
help determine and refine unsafe operating practices.
3:45 PM
Vehicle Situational Awareness and Mobile Mining Equipment
Tracking System
B. Thompson; Military, Mining and Industrial Markets, CCT &
Associates, San Diego, CA
A powerful multiuse, multipurpose Rugged Vehicle Situational Awareness and
Tracking System incorporate advanced military systems for unprecedented communication,
vision, position and monitoring capabilities for Heavy Mobile
Mining equipment.
4:05 PM
Dump Height Optimization in High-impact Shovel
Loading Operations
N. Aouad, S. Frimpong and J. Owusu; Mining And Nuclear
Engineering, Missouri S&T, Rolla, MO
Dump height has an important role in truck and operators whole body vibrations
(WBV) during high-impact shovel loading operations (HISLO). The shovel dipper
location during loading affects truck productivity and cycle time. Material released
from the dipper under gravity causes impact forces traveling throughout the
truck chassis and reaching the operators cabin and seat. The aim of this paper is to
find the optimum dumping height that reduces the impact forces generated under
gravity. This paper links various dump heights to truck productivity as well as
shockwaves generated throughout the system causing operators WBV.
Mathematical models are generated to solve for the optimum dump height without
sacrificing truck productivity and reducing the amount of vibrations reaching
the operators seat under the ISO 2631 comfort zone. A virtual prototype model of
truck being loaded is developed and simulated within the MSC.ADAMS/View
environment. The solution developed and simulation results in this paper will define
an optimum dumping height that lowers truck and operators WBV; increases
truck longevity and ensure an economic safety during HISLO.
This is the Technical Program as of September 1, 2012. IT IS SUBJECT TO CHANGE.
