FIELD: monitoring and measuring equipment.
SUBSTANCE: invention discloses a system, a method and a controller for detecting slipping along the bottom of a long-term development system. System includes a detection device installed in the main drift. First indicator device, located at contact boundary between cantilever reloader and face scraper conveyor, to indicate position of contact boundary between cantilever reloader and face scraper conveyor to detection device. Indicator device of conveyor, installed on belt conveyor. Controller, including electronic processor and memory, wherein controller is connected to detection device and is configured to determine position of contact boundary between cantilever reloader and face scraper conveyor, based on signal from first indicator device, determining first distance between position of contact boundary between cantilever reloader and face scraper conveyor and main girder line and determining position of belt conveyor, based on the third signal from the third display device, determining the second distance between the belt conveyor and the main entry line and generating the slanting slope indication, based on first distance and second distance.
EFFECT: detection of sliding in the development system with long faces.
