Overview

Requirements to collect groundwater monitoring data amid safety risks 

In mine groundwater monitoring networks, it is common to make regular visits to piezometers for data collection, downloading, and processing, which is a time-consuming process involving safety risks associated with travel to remote monitoring sites. Moreover, the periodic data collection introduces a time-lag that can affect the promptness of remedial actions. 

Challenge

Managing wall failure risks in dams and tailings storage facilities 

Effective management of wall failure risks in dams, tailings storage facilities, and open cut pits is crucial to prevent potentially catastrophic impacts. Given the high stakes involved, it is imperative to adopt approaches that ensure an extremely high level of risk mitigation.  

However, traditional methods of collecting groundwater data fall short in terms of efficiency and speed, posing significant challenges. Therefore, the mining site is looking for more streamlined and expedited approaches for gathering data. 

Solution

Real-time groundwater monitoring and automated alerts to support TARP

In order to enhance groundwater monitoring efforts across its operations, the mine implemented Envirosuite solution that focuses on monitoring groundwater pore pressure. This was made possible by establishing a network of strategically placed piezometers, which were augmented with IoT data communication devices, leveraging the existing instruments.

Using Envirosuite’s Omnis solution, monitoring data from remote locations across the expansive mine site could be efficiently and continuously transmitted. Once the data reaches Omnis central engine, it undergoes automated processing to extract valuable insights and inform a comprehensive triggered action response plan (TARP). 

The TARP plays a crucial role in ensuring proactive management of groundwater pore pressure. By analyzing the real-time data and comparing it to desired ranges, the system is now capable of identifying any concerning trends or deviations. In such instances, an alert is generated within the TARP, promptly notifying the ground staff about the need for immediate remedial action. 

Additionally, the mine is able to significantly expand its groundwater monitoring efforts to cover a staggering 100 locations throughout its operations. This expanded monitoring capability allows for a more comprehensive and detailed understanding of the groundwater conditions, thereby facilitating better risk management and mitigation strategies. 

By leveraging technology and harnessing the power of real-time water monitoring, the mine has not only improved the efficiency of its groundwater monitoring but also enhanced its ability to prevent potential hazards and minimize the risk of adverse impacts. Envirosuite platform provides valuable insights and timely alerts, empowering the mine's personnel to take proactive measures and ensure sustainable yet responsible mining practices.
