Calculation methodology of metal wedge-slot boom locks
Authors:
Abstract
It is known that the strength of rod locks fixing is one of the most important conditions for the performance of the rod support. Soviet and foreign researchers differently define the parameters of metal wedge-slot boom locks. The use of such rods is considered expedient mainly in rocks of medium strength (with a coefficient of strength f according to M. M. Protodyakonov from 5 to 8) and to a lesser extent - in strong rocks (f from 8 to 12). However, to date there is no published methodology, simple and convenient for practical calculations.
