Station 9 -Installed in May, 2014 -GPS Station.
Station 10 -Installation in progress (Tentative July 2014) -GPS Station.
Each borehole is continuously monitored with an automatic data acquisition system. The acquisition
system shares power and telemetry with the GPS system via Intuicom radios. These radios transmit
data through repeater stations to the Trapper Mine office. The inclinometer and piezometer data is
saved to a server in the Trapper Mine office. The GPS data is processed on the same Trapper Mine
server. All data is transferred to a secure SNC Lavalin Transportation USA Inc. Data Center server.
All data is archived both on the secure SNC Lavalin Transportation USA Inc Data Center server. All
data is archived both on the Trapper Mine server and the data center server.
Instrumentation locations are shown in Table 3.3-4.
Station locations are shown on Figure 3.3.3-1.
Stations may be added or deleted as mining progresses through the slide area.
Selected data from active monitoring stations will be provided to DRMS semi-annually (March and
September).
