ERGONOMIC INTERVENTION THROUGH THE DESIGN OF JUMBO DRILL RIGS AND ITS EFFECT ON COST SAVINGS AND WORKERS HEALTH AND SAFETY

Abstract Industrial injury occurrences are an ongoing concern for Mine Operators. Along with the personal suffering of injured workers comes an increase in compensation and productivity costs. Growing recognition of repetitive stress and bodily injuries, accompanied by recent studies, validates the assumption that a relationship exists between ergonomic injuries and machine design. Intuitively, there is a belief that an ergonomically designed machine will reduce repetitive stress injuries through design and education however; quantifying this belief has been a challenge for Mine Operators.

Sandvik Tamrock has undertaken a project aimed at developing a business model to assist in quantifying the benefits of ergonomic intervention. This model focuses on distinguishing and quantifying this method of intervention to allow for a better evaluation of the machine.

For simplicity, the project initially focused on the Face Drill Jumbos. The target of the project was three fold:

 Recognition of the cost drivers for compensation; ergonomic injuries
 Identification of the relationship between ergonomic machine design, and the decrease of the negative effects associated with the cost drivers
 Systematic prioritization for “prevention by design”

The project findings substantiate the expected reduction in injuries and compensation claims. Based on all ergonomic intervention studies conducted, each case showed a reduction in compensation cost; through prevention by design, one can reduce the amount of potential risk. The paper addresses the resources and methodology used, along with the findings and its relevance to the issues that face the Mining industry.
