  1. SURFACE HAULAGE National Mine Safety and Health Academy John G. Tyler 304-256-3541

  2. Surface Powered Haulage Analysis Of Surface Powered Haulage Accidents January 1, 1990 to July 1, 1996

  3. Scope of Analysis • Surface Powered Haulage Accidents • Self-propelled Mobile Equipment • Serious Accidents

  4. Accident Review • MSHA Accident and Injury Reports • MSHA Fatal Accident Reports • Mine Operator Accident Reports (Part 50) • U.S. Bureau of Mines Studies

  5. Summary of Findings • 4,397 Haulage Accidents • 1,300 Truck Accidents • 640 Truck Accidents Resulting in Traumatic Injury • 139 Fatal Accidents

  6. Major Factors • Steep Road Gradients vs. Load Limits • Dump Locations • Roadway and Dump Berms • Defective Equipment • Maintenance Practices • Obstructed Visibility • Truck Loading and Unloading Practices

  7. Common Accident Causes Fatalities • Road Gradients Exceeding 7% 36 • Brakes or Steering Failure 20 • Trucks Overturning at Dumps 25 • Obstructed Vision 15

  8. SURFACE HAULAGE FATALS -1994 THROUGH 1997 • Total=161 This total includes classifications (such as machinery) that involved people that were in some way working on, near, or under haulage equipment or performing a haulage function such as grading a haulroad or repairing a truck. They were all haulage related.

  9. SurfaceLoading And Haulage Includes: • Roadways including those providing access to pit areas, dump sites, stockpiles, and reclamation areas. • Trucks • off-road, highway, service, delivery, mantrip • Endloaders • Conveyors • Shovels • electric, hydraulic

  10. SURFACE LOADING and HAULAGE INCLUDES: cont’d • Crane carriers (these accidents are classified as machinery) • Scrapers • Back-hoes, gradalls, excavaters, dozers (accidents will be classified as machinery but these pieces are used on fills, to maintain roadways,drainage, etc.- all functions directly related to haulage operations)

  11. Surface Loading and Haulage cont’d • Draglines (accidents are not classified as haulage) -but, the operations can affect haulage operations. • Endloaders are used for cleaning drag pits , in certain applications, moving cable trees and cables, and as ground pieces. • Drag maintenance is dependent on service trucks and rubber- tired cranes.

  12. Surface Loading and Haulage: cont’d • Graders • Service trucks • tire trucks, flat beds, grease trucks, fuel trucks,welding trucks, mechanic trucks, and water trucks. • Barges

  13. MINING INDUSTRY FATALS1994-1997 • Total fatals=358 • Total surface mine fatals=232 • Total surface haulage fatals=161 • 45% of all mine fatals were surface haulage related • 69% of all surface mine fatals were haulage related

  14. SURFACE HAULAGE FATALS 1994-1997 • Trucks= 63 Crushers= 5 • Maintenance= 19 Draglines= 3 • Dozers= 10 Endloaders= 13 • Tire work= 5 Graders= 1 • Trains= 5 Excavators= 2 • Small vehicles= 13 Forklifts= 1 • Conveyors= 15 Scrapers= 1 • Cranes= 3 Shovels= 2

  15. WHERE ARE FATALS OCCURRING AT SURFACE MINES? • Trucks= 39% Cranes=2% • Haulage Maintenance=12% Draglines=2% • Conveyors=9% Shovels=1% • Endloaders=8% • Small Vehicles=8% • Tire Work=3% • Trains=3% • Crushers=3%

  16. What were these people doing when they were killed?

  17. Truck Drivers • While driving the truck; • traveled out of roadway (some went in water and drowned and others went over embankement ) • were not wearing a seat belt ( thrown out or jumped out of truck ) • lost control on steep grade • overtraveled over the edge of a dump

  18. Truck Drivers (cont’d) • While driving • raised bed into energized power lines ( in one case raised tarp rigging into power ) • did not secure bed in travel position before moving • pulled in front of moving train at crossing • did not use positive two way communication

  19. Truck Drivers (cont’d) • Other work with truck; • out of truck on ground and was ran over with other equipment • fell off top of truck • ran over by truck because park brake did not hold or was not set • unloading truck and struck by load • truck caught on fire • under bed when it fell

  20. Truck Drivers (cont’d) • Other work with truck; • tried to catch runaway truck and was run over by truck • load shifted on truck while driving and mashed cab and driver

  21. Maintenance Related To Haulage • Working under raised equipment • not secured or blocked • Not in clear when equipment started or moved • Electric equip. not locked out ( blocked against movement) • Fire • welding or using torches • Tire maintenance not considered here

  22. Endloaders • Lost control on steep grade • Caught by boom or bucket • Riding outside cab • Traveled out of road or over edge of dump • Not wearing seat belt • Ran over another person on ground

  23. Powered Haulage Issues • Pre- Operational Equip.Check • Maintenance/Brake • Adj. System Leaks, Hyd.& Air. • Low Air Warning System. • Steering System (Emergency)

  24. Powered Haulage Cont. • Haul Roads & Dumping Sites • Visibility • Communications • Industry Statistics
