FIELD: mining.
SUBSTANCE: invention refers to drilling elements and anchor bolts used at mining works and tunneling. The drilling element has opposed the first and second ends and a rod passing between the ends. At least one drilling head is positioned on the first end. The second end is adjusted for connection to a drilling facility to ensure rotation of the drilling element and to transfer axial force onto it. Along and around the rod there is assembled a bushing while the passage formed between the bushing and the rod facilitates flowing of fluid medium along the rod. Also there is suggested the drilling bit, the method of drilling with a drilling element and the method of stabilisation of rock.
EFFECT: increased efficiency of process of rock bolting and reduced costs for drilling elements.
