A GPS Based System for Minimizing Jolts to Heavy Equipment Operators
What Describes a method for assessing equipment jolting using a combination of "black boxes" called Shox Boxes and an onboard GPS system. The Shox Box system reviews data in real time, onboard the vehicles, 24 hrs a day, and sends pertinent... Read more
Methods to Minimize injuries in Materials-Handling Processes in Underground Mines
Data from the Mine Safety and Health Administration for the years 1989-1999 were studied to find out if there were any trends in materials-handling accidents and if so, to determine what tasks were involved and the sources of injuries. Several... Read more
Minimizing Respirable Dust Exposure in Enclosed Cabs by Maintaining Cab Integrity
A research into the effects of constant cab depressurisation on the respirable dust concentrations within the cab, and recommendations to reduce concentrations. ... Read more
LHD Operator Posture Assessment
What To determine the postural deviations and low back load required for line of sight from the operator's position. Why The bi-directional nature of load haul dump (LHD), vehicle design dictates the operators sit in a centrally located seat position, perpendicular to the... Read more
Shuttle Car Cab Modifications
Problem The current design of the shuttle car cab has resulted in a number of back, shoulder, neck and knee injuries. Solution A shuttle car design review team instigated boundaries and design modifications to reduce ergonomic and health and safety hazards. Engineering solutions... Read more
Guideline for Vehicle Seating
This guideline provides information on the correct design and adjustment of vehicle seating to prevent injury. Guidance on positioning of the steering wheel and seat to provide back support and methods of reducing vibrations are discussed. Diagrams showing the correct... Read more
Minerals Industry Safety Handbook Part 5 : Equipment and Machinery
This chapter of the Minerals Industry Safety Handbook covers the mine site hazards associated with machinery. Sections in this chapter cover hazards and where they may occur (confined spaces, elevated platforms etc.), hazardous plant (pressure vessels, guarding of moving parts),... Read more
Major Hazard Standard Related Document: Assessment of Surface Earthmoving Equipment
This document consists of a template used to assess Surface Earthmoving Equipment. A table containing a list of items from specifications is provided. Compliance of the item, or an alternative method of verification, is to be recorded in the table,... Read more
Fatal Machinery Accident, Sanborn Creek Mine. Somerset, Colorado. U.S.A.
What Longwall tailgate shearer operator was fatally injured when struck by a broken high pressure hydraulic line Why Failure of a 1-inch female by 1-inch male Dayco staple lock fitting in the tailgate high pressure emulsion feed hose. This fitting failed due to... Read more
Bad Vibrations
The nature of whole-body vibration (WBV), its sources and prevention are the subject of this Handbook. It aims to assist people in the mining industry to identify and manage the risks associated with vibration exposure. It is for use by... Read more
Enhanced Surface Control for Roof and Rib Support
The risk of injury caused by minor roof falls continues to increase in underground mining. Most ground control injuries result from small rock falls that occur in a supported area, but do not involve the failure of the support system.... Read more
E-Facts: Prevention of vibration risks in the construction sector
Vibration is a serious health risk for workers in the construction sector. The two main types are hand-arm and whole-body vibration. The former can cause neurological and motor disorders in the hands and fingers, as well as circulatory disorders in... Read more
Human Factors Engineering Specific Analysis
To provide the reader with information on wether a tool or piece of equipment is accepatable in terms of Human Factors engineering (HFE) design which can be very dependent on the manufacturers testing program prior to marketing. Many HFE issues,... Read more
Ergonomic Design Handbook for Shearers
The information in this report is structured so that it can be used when designing new shearers or when assessing prototypes. If modifications are being planned on existing plant, or an existing machine is to be evaluated, then the designer... Read more

What "The objective of this study was to systematically characterize the ergonomic hazards associated with excavating operations." ... Read more
Ergonomic Risk Factors: A Study of Heavy Earthmoving Machinery Operators
What This paper reports the results of a study performed to evaluate ergonomic exposures among operators of heavy construction equipment. It also provides recommendations for reducing ergonomic exposures such as vibration and postural stress. ... Read more
Whole-body vibration and postural stress among operators of construction equipment
What It has been suggested that operating engineers (OEs) are exposed to two important risk factors for the development of musculoskeletal disorders: whole-body vibration and non-neutral body postures. This review evaluates selected papers that have studied exposure to whole-body vibration and... Read more
Back Injury Control Measures for Manual Lifting and Seat Design
Development of more efficient supply-handling systems, innovative approaches to supply-handling problems, and proper design of manual lifting tasks can greatly reduce the risk of back pain, as can attention to proper design of seating. Engineering controls that emphasize workstation and... Read more
Laboratory Investigation of Seat Suspension Performance during Vibration Testing
Researchers performed laboratory studies on four passive and two semi-active seat suspension designs. These six seat suspension systems were tested and analyzed, for vertical vibration only, using the ISO 5007 Standard. ... Read more
Influence of Posture and Multi-Axis Vibration Onreation Time Performance and Perceived Workload
Whole-body vibration exposure has been found to negatively influence health, comfort and performance. Performance measures are affected by the task and situation investigated, so it is difficult to make detailed recommendations based on fundamental research. There is little knowledge on... Read more
