Nordic Gold's mine relies on EHP's real-time online environmental monitoring and alarms, the so called EnMonCon concept.

The environmental monitoring program of the quickly re-opened Raahe Laiva gold mine was modernized in summer 2018 in co-operation with the mine staff, EHP Environment Ltd., KVVY Tutkimus Ltd. and Centre for Economic Development, Transport and the Environment of North Ostrobothia. This was the first time in Finland’s history, when a mine’s monitoring program was changed to rely on real-time online water quality and flow measurements.

In this new environmental monitoring program the total amount of monitoring points was decreased as it counts on seven EHP’s real-time online water flow and quality monitoring stations installed to critical points. These monitoring stations are located in the internal and external water system of the mine. Reliable, real-time measurements reveal any sudden change in water flow or quality. These monitoring stations measure flow, level, water temperature, pH, electrical conductivity and suspended solids. EHP Environment together with Nordic Gold is responsible for the data quality control and stations’ sufficient service.

 

”EnMonCon concept and EHP’s real-time online monitoring stations bring excellent value to the mines environmental monitoring. This monitoring data is used at the mine to watch over the water quality, to control water pumping and to control the water balance. With online measurements we can even predict environmental impacts and at best they can prevent harmful impacts when critical data is received immediately.”

– Riina Mäkelä, environmental manager, Nordic Gold Oy-

 

The mine’s main pumping station’s flow and water quality is now controlled in real-time. The area has altogether six other water monitoring stations and one weather station.

 

EHP’s online monitoring stations are located in the external and internal water system of the mine site.
