摘要： The invention relates to an anchor plate system for a rock bolt with a load indicator, containing two bolting washers, at least one lining element and a load indicator element located between the bolting washers, characterised in that bolting washers (5) have a dome shape, are at the same time the components of the anchor plate, and are superimposed one after another on the rod (1) of the bolting protruding from the hole (2), and are secured by the head (4a) of the bolting or the nut (4b), with the domed convexities of the bolting washers (5) are located on opposite sides, while between the bolting washers (5) there is thin-walled container (6) of known compressive strength filled with a liquid colouring agent.
