Unresolved issues of mine shaft drilling

Abstract

Of all the currently known methods of sinking mine shafts, only the drilling method mechanizes all the main links of the driving cycle and allows automation of production. Drilling method, as well as other special methods of excavation, is applicable in difficult mining‑geological 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 support 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 shaft sinker is eliminated.
