Studies on Rock-Breaking of Positive Disc Cutter and Edge Disc Cutter

Applied Mechanics and Materials, 2014
Based on TBM disc cutter layout, a rock-breaking model of positive disc cutter and edge disc cutter is built. Sequential rock-breaking of the two cutters under different parameters is simulated; rock fragmentation, three-axis force and energy consumption are studied; optimal rock-breaking condition with different parameters is determined; feasibility ...

Rock excavation by disc cutter

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1975
Abstract Partial factorial experiments have been undertaken to study the effect of changing the principal geometrical variables on the performance of disc cutters operating in both the unrelieved and relieved cutting modes. A simple mathematical model is proposed which, on the evidence of the experimental data, is found to provide a good description

Factors Influencing Disc Cutter Wear

Geomechanics and Tunnelling, 2008
AbstractDisc cutter wear in mechanised tunnelling has a strong influence on costs and performance in hard rock and soil materials. Wear is affected by several geological and technical factors. Several aspects have been considered in prediction models and case studies.

Characteristics Analysis of TBM Disc Cutter Ring

Advanced Materials Research, 2010
Disc cutter is the key part in Tunnel Boring Machine (TBM). Wear and tear of disc cutter is the main reason of low efficiency and high cost of this machine. Forces and deformations of disc cutter ring are foundation for its design and assembly. In this paper, the analysis of stress and deformation are carried to study their distribution; Wear mechanism

Layout design for disc cutters based on analysis of TBM cutter-head structure

Journal of Central South University, 2018
Studies to date have failed to consider gage disc cutters’ variable cutting depth and the constraints of cutter-head welds, and have ignored the coupling mechanism between the profile of the full-face rock tunnel-boring machine (TBM) cutter-head and the assembled radius layout of the disc cutters.

Analyses of TBM disc cutter forces – application possibilities

Geomechanics and Tunnelling, 2019
AbstractForecasts made during tunnelling of the daily advance, to control the machine, specify the lining and verify system behaviour are of great importance for safety and for the success of the whole project. In practice, such forecasts are obtained in deep tunnels by probe drilling, leading to downtime periods and by analog/digital face ...

Impact of Cleaning Efficiency on Disc Cutter Drilling Performance

Volume 9: Offshore Geotechnics; Petroleum Technology, 2023
Abstract Large diameter drilling operations, including tunnel boring and raise boring, are capital-intensive projects. As such, proper estimation of time and cost is critical to the planning of the drilling project. To arrive at the correct estimation of the drilling time during the drilling phase, accurate prediction of the drilling ...

Rock Failure and Crack Propagation Beneath Disc Cutters

Rock Mechanics and Rock Engineering, 2014
Analyses of rock failure mechanisms beneath disc cutters are presented. Full-scale cutting tests are conducted to assess the global energy input in comparison with rock chips and excavated volume. Small-scale cutting tests are subsequently used for macro- and microscopic analyses of rupture modes and crack propagation.

A recent application—the driven disc cutter

Journal of Terramechanics, 1984
INTRODUCTION THE accompanying paper by A. R. Reece describes a new type of submarine cable plough in which a wedge sectioned slice o f soil is cut out by one or more disc cutters, and this is shown in Fig. 6 o f t h a t paper. The disc shown in that figure is a simple trial device, the final design being much more complicated, including a spring ...
