The SenzLogic 2.0 is a ruggedised system using software created by PDT and hardware developed by WSN. Using state-of-the-art gas sensors from Draeger Safety, the system monitors emissions while the machinery is performing routine mining operations. Emissions measurements are integrated with engine diagnostic information to develop detailed models which reflect various duty cycles and corresponding emission profiles. Data can be logged locally, downloaded daily or transmitted wirelessly to surface through existing infrastructure for immediate interpretation and analysis.

The technologies form the foundation of a platform for real-time monitoring of diesel equipment operation including the continuous evaluation of equipment health, operational efficiency and the impact on mine worker safety. Paul Sheremeto, president and CEO of Pattern Discovery Technologies, noted that in addition to eliminating time consuming and inconsistent manual emissions testing procedures, it will streamline maintenance operations through remote monitoring and detection of deteriorating equipment performance.

He explained: “Not only does the SenzLogic system provide a more accurate picture of real-time emissions in these environments, it also provides unprecedented early insight into potential engine problems for maintenance planning. The emissions profiles are leading indicators of issues involving intake systems, exhaust systems, fuel injection systems and cooling systems. Combining emissions data with engine data will help to pinpoint these potential problem areas. The next phase of development is to combine this real-time data with maintenance system information to predict equipment failure and plan maintenance intervention actions. This combination will dramatically streamline maintenance functions by reducing unexpected breakdowns through early diagnosis and provide useful feedback on effectiveness of maintenance activities once they have been performed.”

CEMI recognises that this initiative will have a major impact on mining operations across Canada. Douglas Morrison, president and CEO of CEMI, commented: “Real-time monitoring of the exhaust gases of underground equipment when it is under full load is one of the best ways to assess engine performance. There are several systems available today that make it possible to accurately monitor ambient air quality in mines. Combining ambient data and engine data helps us understand why the conditions are the way they are what we need to do to improve them.”

CEMI also stated that, given the benefits to Canadian mining and the opportunities to improve mining operations, it has committed full support to the ongoing research and development of this real-time emissions monitoring initiative.
