Roof support monitoring for longwall system
First Claim
1. A method of monitoring a roof support of a longwall mining system, the method comprising:
- obtaining, with an electronic processor, pressure information for the roof support;
determining, with the electronic processor, whether the pressure information is indicative of a first type of pressure failure of the roof support by determining whether the roof support achieved set pressure within a first predetermined amount of time;
determining, with the electronic processor, whether the pressure information is indicative of a second type of pressure failure of the roof support, the second type of pressure failure being different than the first type of pressure failure; and
generating, with the electronic processor, 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.

Abstract
A monitoring device and method for monitoring a longwall mining system having a roof support, the roof support including a pressure sensor to determine pressure levels of the roof support during a monitoring cycle. Pressure information is obtained for the roof support. An electronic processor then determines whether the pressure information is indicative of a first type of pressure failure of the roof support and whether the pressure information is indicative of a second type of pressure failure of the roof support. An alert is generated 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.

9. 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
