Application of sinking machines during construction of mine shafts is an innovative technology that allows to increase the average sinking rates by 2–3 times and combine all major labour-consuming operations entailed in rock blasting, mucking and shaft lining into a continuum shaft boring operation. Whilst analysing the experience gained in this method, one has to indicate that the increase in water inflow in the shaft sum up to 30–50 m3 and results in sharp decrease of productivity of sinking. One of the technical solutions that tackles this problem is to apply effective techniques of ground water control. The paper deals with various aspects of grout treatment method practised during shaft sinking in Donets Coal Basin, Ukraine and presents a case history.
