SPEED OF SINKING.--Mines may be divided into two cases,--those being developed only, and those being operated as well as developed. In the former, the entrance into production is usually dependent upon the speed at which the shaft is sunk. Until the mine is earning profits, there is a loss of interest on the capital involved, which,
The Vertical Shaft Sinking Machines (VSM) for shafts with lower depths developed by Herrenknecht have already proven successful in numerous applications. Based on these project experiences, the SBR boom with cutting drum has been modified to meet the requirements of shaft sinking in the mining industry and the working platforms have …

Locate the governor arm and shaft on the engine. Loosen the governor arm nut so the arm can move freely. Hold the governor shaft with pliers and rotate it in the direction it naturally moves. Move the throttle to the wide-open position while holding the governor shaft in place. Tighten the governor's arm nut to secure the governor in position.
The rest of the 45-m long machine catches up following this initial cutting, which is automated by a series of lasers that ensure the machine is on the correct course and using optimal force. This cutting station is followed by two shaft gripping stations for machine support within the shaft.
