In recent years, the Leningrad Mining Institute has developed several stands for post-repair tests of drives of loading machines, cleaning and sinking combines in the conditions of production associations "Leningradslanets", "Kuzbassugol" and "Vorkutaugol".

Cleaning (KSH-1KG, KSH-ZM) and tunneling (PK-ZR, 4PU, PK) combines used in the production associations Kuzbassugol and Leninskugol are undergoing overhaul at the ore repair plant Krasny Oktyabr (Leninsk-Kuznetskiy) ...

In the GDR, much attention is paid to the development of vibrating machines and devices that can be successfully used in the automation of production processes in the mining and construction industries. …

Practical needs of approximation of scientific research to production dictate the necessity of studying natural objects in natural (industrial) conditions. This requires reversal of the classical vibration test bench-object scheme, i.e. not the object is installed on the test bench (often it is simply impossible), but the object itself is transformed into a full-scale research test bench by attaching to it a vibration device consisting of a vibration exciter and measuring systems.
