Tunnel Boring Machines (TBM) Roadheaders (TSM)

Tunnel boring machines are full-face cutting machines, which means that, unlike road headers, they excavate the entire tunnel cross-section in one step. TSM: Roadheaders belong to the category of peripheral milling machines due to their design. Since today's road headers work with cutting heads, these machines are also called cutting head machines.

[PDF] A Model to Predict the Performance of Roadheaders

In this paper the recent sewerage and metro tunnel projects in Istanbul are summarized. A model improved as a part of NATO TU Excavation project, that relates the cutting performance of mechanical excavators to rock mass cuttability index, is discussed with the recent data collected. The model may serve as a useful guide to contractors and machine manufacturers prior starting a tunnel project.
