Patent number: 10655468Abstract: A method of monitoring a longwall shearing mining machine in a longwall mining system, wherein the shearing mining machine includes a shearer having a first cutter drum and a second cutter drum, includes receiving, by a processor, shearer position data over a shear cycle. The horizon profile data includes information regarding at least one of the group comprising of a position and angle of the shearer, a position of the first cutter drum, and a position of the second cutter drum. The method also includes analyzing the shearer position data, by the processor, to determine whether a position failure occurred during the shear cycle based on whether the computed horizon profile data was within normal operational parameters during the shear cycle, and generating an alert upon determining that the position failure occurred during the shear cycle.Type: GrantFiled: June 28, 2019Date of Patent: May 19, 2020Assignee: Joy Global Underground Mining LLCInventors: Paul M. Siegrist, Nigel J. Buttery, Lachlan Palmer

Patent number: 10184338Abstract: 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.Type: GrantFiled: August 4, 2017Date of Patent: January 22, 2019Assignee: Joy Global Underground Mining LLCInventors: Paul M. Siegrist, Nigel J. Buttery, Kirabo Kiyingi

Patent number: 9739148Abstract: A monitoring device and method for monitoring a longwall mining system having a plurality of roof supports, each roof support including a pressure sensor to determine pressure levels of the roof support during a monitoring cycle. Pressure data is obtained for the plurality of roof supports. The pressure data includes pressure information for each roof support of the plurality of roof supports over a monitoring cycle. The pressure data is analyzed to determine, for each roof support, whether a first type pressure failure occurred during the monitoring cycle. A fault quantity is generated that represents the number of roof supports determined to have had the first type of pressure failure occur during the monitoring cycle. An alert is generated upon determining that the fault quantity exceeds an alert threshold.Type: GrantFiled: August 28, 2015Date of Patent: August 22, 2017Assignee: Joy MM Delaware, Inc.Inventors: Paul M.
