INVESTIGATION OF PROCESS DYNAMICS OF TBM EXCAVATION
Lazarová E., Krúpa V., Ivaničová L., Kruľáková M.
pages 387 - 390, full text

Full-profile tunnelling with TBM enables to monitor the excavation process data, serving for further investigation of rock cutting mechanism. The monitored data provides calculation of the specific cutting energy, the contact stress of the disc cutter acting on rock surface in the instant of rock disintegration, which defines the rock compressive strength, or other useful variables. The paper discusses the relation of such calculated rock strength and specific energy in the dynamic process of rock excavation in natural conditions of rock formation. Process dynamics was described by first order linear differential equation with constant coefficients.
