Mine Face
The second display in the Face Display application shows each individual roof support and it's current status.
This chart is live - it will animate as new data arrives.
Each support is coloured based on the pressure the roof is applying to the support. High pressures indicate excess stress, low pressures can indicate that the supports aren't properly 'set' against the roof.
The current location of the shearer is shown with a green outline.
Each support also has indicators which show particular conditions, such as…
LP - Low Pressure on one of the two 'legs' of the support that hold the roof up. This may appear on the left or right to indicate which of the two legs it appears on.
PUSH - The support is currently pushing the panline forward, the first step in moving.
PULL - The support is currently pulling itself forward, finishing its movement.
LOW - The support has dropped off the roof.
Clickable Supports
You can also click on supports to see more detail.
This includes both simple indicators - such as a support not being 'set' against the roof - and complex tests that check for combinations that indicate specific problems, such as trying to differentiate a failed sensor vs a leaking leg.
