Simulating the effect of disc erosion in TBM disc cutters by a semi-infinite DDM
Arabian Journal of Geosciences, 2014Underground excavation in rocks can be accomplished in several steps. The cutting action of mechanical tools such as disc cutters used in tunnel boring machines (TBM) is one of the most basic steps. Indentation of TBM disc cutters into the rock can produce rock chips in different scales.

Establishment of TBM Disc Cutter Dynamic Model for Vertical Vibration
2009On the basis of reasonably simplifying the interaction process of TBM disc cutters and rock on tunneling surface, the shape of effective breaking pit is used as the lower boundary condition of vibration system and based on the equivalent stiffness method, two general differential equations of TBM disc cutter for vertical vibration are established ...

Géotechnique Letters
Disc cutters are the most commonly used cutting tools in various types of tunnel boring machines (TBMs). Estimating the force required for cutting a specific type of rock using disc cutters is a crucial aspect of the TBM cutter head design and the prediction of TBM performance.

Stress distribution in attachments of disc cutters in heading drivage
Journal of Mining Science, 2015The authors substantiate new engineering designs for selective heading machines and cutter–loaders fitted with screw–type cutters. It is proposed to use biconical and conical disc tools and their attachment units to polygonal prisms to equip both bits of heading machines and screw cutters of cutter–loaders to cut structurally heterogeneous rock mass ...

An Economic Study of Oscillating Disc Cutter Technology
This thesis considers the economic benefits of the Oscillating Disc Cutter (ODC) for use in tunnel development machines in hard rock. Mechanical excavation machines have the potential to significantly reduce direct and indirect tunnel development costs over drill and blast.The Oscillating Disc Cutter (ODC) excavates rock using a disc similar to those ...openaire +2 more sources
An experimental study of rock fracture by disc cutter [PDF]
The number and size of projects that involve underground excavation are increasing steadily owing to rapid growth of the urbanisation patterns and the increasing demand for excavation of deeper mineral deposits. Our knowledge of rock breaking process has not been developed sufficiently to cope with the demand. An experimental programme was initiated to
