LEVEL MONITORING FOR LONGWALL METHOD SYSTEM Russian patent published in 2020 - IPC E21C35/08 E21C35/24 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a method and apparatus for monitoring a coal cutter for continuous development in a continuous development system, note here that cutter comprises cutting device having first cutting drum and second cutting drum to receive, by means of processor, horizon profile data during cutting cycle. Horizon profile data include information on at least one of a group comprising the position and angle of the cutter device, the position of the first cutting drum and the position of the second cutting drum. Method also includes analyzing position data of the cutter device by means of a processor for determining whether a positioning failure occurred during the cutting cycle, based on whether the calculated horizon profile data were within normal operating parameters during the cutting cycle, and generation of warning after determining that during the cutting cycle positioning failed.

EFFECT: technical result consists in improvement of coal extraction efficiency.
