CONSTRUCTION CHARACTERISTICS OF MECHANIZATION UPON TUNNEL EXCAVATION

Rudarsko-metalurški zbornik, 1995
This paper presents the characteristic mechanization upon tunnel excavations using the standard method. The impact is given to the construction particularities of the equipment, which affect the coordination between the mechanization and particular technology of the performances, as well as the modern concepts affecting the humanization of labour ...

Operation Parameters Matching for Main Mechanisms of Open-Pit Excavators Employed in Rock Excavation

2018
It is shown that operation parameters of the main mechanisms of an open-pit excavator (hoisting and thrusting velocities) vary within a wide range during the process of rock excavation. Based on the computing experiment aimed to calculate EKG-20A excavator parameters, hoisting and thrusting velocities were determined for a specified law of bucket ...
