Innovation and working with industry

AMIRA Project P1217

Gold Fields is a major sponsor of AMIRA International’s P1217 “Evaluation of Tailings Storage Facilities (TSF) monitoring technologies” collaborative project.

AMIRA International’s research project P1217 will evaluate and document currently available technologies for monitoring the condition of Tailings Storage Facilities (TSFs), complemented by a program of installing selected instrumentation and monitoring at a limited number of sponsor sites. In conjunction, a numerical model (the digital twin) will be developed to enable predictive scenario analyses.

Aside from detailing available (and emerging) technologies, the project will guide the need to develop novel instrumentation, e.g., for detecting the potential onset of static liquefaction, something which current instrumentation is unable to do.

Gold Fields TSF Technology review

Gold Fields (GF) carried out a technology review in 2019 to assess available TSF monitoring technologies that may apply to Gold Fields. This review indicated a significant amount of monitoring technology available, with varying levels of maturity and implementation experience. There was an opportunity for Gold Fields to supplement existing monitoring approaches and technologies.

The focus was to install these technologies, with a particular focus on facilities with higher consequence categories. A discussion paper was circulated for comment to all GF sites in 2019. All sites have embraced and adopted the proposed technologies and are either investigating or implementing the technologies.

ICMM TSF monitoring working groups

Gold Fields is represented on the following ICMM tailings working groups:

  • Track 1, technology landscape review with the aim of eliminating/reducing tailings
  • Track 2, technology landscape review and vendor engagement in support of cost-effective scaling up of tailings dewatering and material handling technologies and approaches.
  • Track 3, development of a Tailings Guidance document
