Unresolved issues of mine shaft drilling
Abstract
Of all the currently known methods of mine shafts only the drilling method mechanizes all the main links of the tunneling cycle and allows automation of production.Drilling method, as well as other special methods of excavation, is applicable in difficult gropogeological conditions (for example, large inflows of water into the excavation). However, in comparison with the methods of freezing and cementation, it has a number of advantages. By this method, rock destruction, its removal and temporary fixing are carried out in parallel and with the help of mechanisms controlled from the ground surface, i.e. the most labor-intensive and dangerous profession of a sinker of vertical excavations is eliminated.
