Design and operating practices of the waste rock stockpile: Part II-risk assessment
Colin Hardie, BBA; Luciano Piciacchia, BBA; Antonio Vides, BBA
The risks associated with the construction, operation and closure of a Waste Rock Facility (WRF) can be significant. This paper demonstrates the impacts that design, construction and operation can have on the overall risk associated with such facilities. The current ongoing operation methods is discussed. This is followed by an evaluation of risk for the proposed LOM configuration, with and without mitigating measures with respect to design, construction and operation. The risks associated with current operations as well as the configuration at closure carried with it a level of risk which the operator found inappropriate. Design, construction and operating recommendations, which mitigate risks to acceptable levels were disucssed. This paper relates the findings of the case study.
