METHOD OF HORIZONTAL CONNECTING SHOOTING OF SUBSURFACE HORIZONS Russian patent published in 2019 - IPC G01C15/12 

FIELD: mining.

SUBSTANCE: invention is intended for the mining industry and relates to methods for producing horizontal connecting surveys of subsurface horizons through vertical or steeply inclined workings, consisting of solving problems of centering and orientation. Method of horizontal instrumental survey of subsurface horizons through a single vertical or steeply inclined working includes installation of equipment on the oriented and main horizons, conducting preparatory works related to the creation of a vertical projection plane, conducting angular-distance measurements in the workings on the main and oriented horizon and the subsequent cameral processing of measurement results using a computer. In this case, the vertical projection plane is created by a laser plane builder, and measurements to points located at the intersection of light traces created by laser planes on the walls and roof of the junction of the connecting vertical and subsurface workings are performed using electronic total station in a non-reflective mode for calculating directional angles of the sides and coordinates of the points of filming network on the oriented horizon.

EFFECT: improving the accuracy and safety of work during the connection survey, as well as reducing the number of preparatory operations and reducing the impact of the air environment.
