METHOD AND DEVICE FOR DETERMINING POSITION Russian patent published in 2015 - IPC E21D23/00 E21C35/24 G01C11/36 

FIELD: mining.

SUBSTANCE: method of determining a position of mechanisms in a working face in underground mining is provided, comprising the following steps: a video camera is mounted in a roof timber area of a roof support with the viewing direction mainly in the direction of an air flow, or opposite it, the camera is oriented so that the vanishing point of the image from the camera is in the area of the right or the left upper corner of the image from the camera, illuminated markings are provided on the mechanisms along the working face in the area of the image from the camera and they are operated, as well as the positions of the mechanisms are determined by means of electronic processing of the markings located on the camera image. Also a system and a video camera for implementing the method are proposed.

EFFECT: providing the opportunity of simultaneous monitoring of the straightness of the working face, recording of a vertical and horizontal deflection of roof supports and the conveyors, controlling automatically the stroke of the roof supports, or to monitor the mining machine.
