Mining & Resources / Tailings Storage Facilities

Managing your rehabilitation sites and tailings facilities

One of the biggest concerns the mining industry faces today is reducing the harmful effects it has on the environment where projects are implemented. As a result, rehabilitation and mine closure is often planned for and considered across all stages of a modern mine development and operation; from design to closure, rehabilitation is a critical component of a company’s environmental project management.

Similarly, tailings management is a critical part of managing the risks of the waste produced during the mining process. These risks can range from potential consequences of a tailings storage facility failure through to groundwater impact due to seepage.

In this article:

  • Find out how you can drive progressive rehabilitation and closure
  • Learn how to drive proactive tailings monitoring and management
  • 8 tools to help you effectively monitor and manage your site or facility

Rehabilitation & Closure management

Decisions about mine closure in Australia have tended to have little consideration of how the land might be used post-mining. However, this is beginning to change, particularly with increased stakeholder pressure, environmental concerns and climate change discussions, and regulatory changes.

Armed with Decipher’s Rehabilitation & Closure solution, including GIS, remote sensing, monitoring and management tools means you can easily capture and analyse a wide range of environmental monitoring data, manage risks and issues around put backfilling, rapid flooding, slope instability and acid generation, and ensure you’re meeting your environmental obligations and compliance with alerts and notifications of exceedances.

Tailings management

With an estimated 3,500 active tailings storage facilities (TSFs) across the globe covering approximately one million hectares of land, and an increasing number of failures occurring and being recorded, it’s clear that a fresh look at the reporting and monitoring of these facilities is needed.

Armed with Decipher’s Tailings Solution, including GIS, remote sensing, monitoring and management tools you’ll have access to a range of tools that enable you to effectively monitor and manage your TSF, and your environmental obligations and compliance.Our solution can be securely accessed by industry, regulators, designers and operators involved in the management of TSFs.

8 tools to help you effectively monitor and manage your site or facility

1. Projects

Setting up projects in Decipher is quick and easy. Simply upload a map file or draw in area boundaries to see your site or facility on the map.

 

2. Map Files

Spatial visualisation of operational datasets provides an effective way to gather insights into various relationships or correlations between environmental performance and other contributing factors. Decipher allows users to upload mapping files as well as integrate with external spatial sources to visualise spatial datasets in amongst client project datasets on the map.

 

 3. Earth Observations

Earth Observations data is being increasingly utilised across a variety of applications such as urban development and infrastrucutre, climate change, biodiversity and ecosystem sustainability, agriculture, water management and mineral resources management. Decipher, utilising Google Earth Engine in our cloud-based platform, is at the forefront of this new era of utilising satellite images and datasets, and are helping pave the way for additional research and increased utilisation and application in everyday use. Our library of available indices (NDVI, NDRE, MSAVI, and NDWI) is constantly evolving to meet the demands of various customer requirements and our highly interactive interface allows users to apply it to other datasets and ‘real life’ scenarios.

 

 4. Environmental Monitoring
Environmental monitoring is critical in understanding environmental health, efficiencies, constraints and upholding compliance, and when done well, can also have a positive impact on the bottom line of an operation. Monitoring involves the process of sampling and analysis of various environmental indicators and contaminants over time to understand and minimise the environmental footprint of large scale projects on the natural environment. Often these datasets are large, complex, stored in a number of different locations, and details can be lost with staff turnover. Decipher provides you with the tools you need to manage your project-specific data requirements and insights to help drive effective environmental monitoring:
  • Create any number of points, parameters and compliance limits and group them to form monitoring programs
  • Plot monitoring data on the map by program, parameter, points, date range and soil depths
  • Easily build any number of compliance limits and standards into the monitoring tool and plot them in charts and tables to flag exceedances
  • Seamlessly integrate with any external or internal laboratory for automatic result validation and import with live alerts of exceedances
  • Create a schedule of sample jobs with predefined sample due dates and sample types with the ability to incorporate a second layer of approval and escalation of overdue samples

 

5. IoT

IoT devices can assist with monitoring the structural movement of mining earthworks for compliance and safety purposes (including rehabilitation, tailings dams, stockpile, excavation monitoring and more). Decipher can integrate with your IoT devices enabling you to visualise the data on the map, and monitor the results in real-time.

 

 6. Obligations

Projects that directly impact the environment and community are often accompanied by a large volume of prescriptive conditions and actions that must be complied with in order to commence and continue a project such as permits, approvals, licences, Ministerial Conditions and mineral titles and so on. Decipher’s Obligations module provides a central, online platform designed to capture important obligation information, enabling you to identify, address and manage key deliverables. To ensure obligation deliverables and deadlines are met, you can establish a set of actions and accountabilities.

 

 7. Stakeholders

Effective stakeholder engagement and upholding stakeholder commitments is key to project longevity and success, as well as driving an organisation’s social licence to operate. Failure to track and document issues, commitments and communications can result in stakeholder dissatisfaction and distrust, and ultimately project failure. Decipher’s Stakeholders module enables you to easily identify and track stakeholder profiles and important stakeholder metrics, including the ability to capture ongoing engagements, highlight trends in stakeholder sentiments and themes, and assign related actions to team members.

 

 8. Actions

Task management is crucial in any operation. In conjunction with other modules, Decipher’s Actions tool allows you to easily create tasks, assign actions to appropriate team members with an ability to incorporate a second layer of approval and escalation of overdue actions. All actions have associated and automatic notifications which ensures that team members are reminded to meet deliverables on time.
