description The invention provides a fully mechanized coal mining face floor line extraction method and a related device, a fully mechanized coal mining face is provided with at least one scraper conveyor, one side of each scraper conveyor is provided with a flexible track, the flexible tracks on the adjacent scraper conveyors are connected through an elastic piece, and the flexible tracks are slidably provided with a positioning device. The method comprises the steps of controlling a positioning device to move along a flexible track, and determining a first space curve; determining a first fluctuating curve based on the projection of the first space curve to the plane where the coal wall is located; and determining a floor line at the intersection of the coal wall and the floor based on the first fluctuating curve. The floor line obtained through the fully mechanized coal mining face floor line extraction method can be used for guiding control over follow-up actions of a coal mining machine, and compared with a manual e
