Roof support monitoring for longwall system

A monitoring device for a longwall mining system having a roof support including a pressure sensor to determine pressure levels of the roof support, the monitoring device comprising:

• a memory;
• and
• an electronic processor coupled to the memory and in communication with the pressure sensor to receive pressure information for the roof support, the electronic processor configured to:
• determine whether the pressure information is indicative of a first type of pressure failure based on whether the roof support achieved set pressure within a predetermined amount of time, determine whether the pressure information is indicative of a second type of pressure failure, the second type of pressure failure being different than the first type of pressure failure, and
• generate an alert in response to determining that the pressure information is indicative of at least one selected from the group consisting of the first type of pressure failure and the second type of pressure failure.
