FIELD: mining.
SUBSTANCE: invention concerns mining and is designed for hydraulic lining control. The hydraulic lining control system includes multiple sections adjustable for implementing of lining functions, i.e. relieving, shifting and arch action. Also each power gear of the system has hydraulic valves close to the respective power gears and divided into groups. Each group is connected to a hydraulic delivery pipe running along the aligned lining section by a group connection line blocked by a group shutoff valve subject to the state of control valves with all control valves unengaged.
EFFECT: improved reliability of lining control.
