Economic efficiency of mechanized methods of rock removal during shaft sinking

Abstract
As it is known, rock loading in vertical shafts of mines, occupying 60-80% of the time of tunneling cycle, is the most labor-intensive and difficult to mechanize process. Therefore, the choice of the most rational method of rock loading is of particular importance. The main criterion for this is usually the total productivity of machines for loading, i.e. only the reduction of time for loading and the increase in sinking speed achieved due to this is taken into account. This completely misses the cost of rock loading, which has a significant impact on the cost of shaft construction.
