Roadheaders offer a unique capability and flexibility for the excavation of soft to medium strength rock formations, therefore, are widely used in underground mining and tunneling
Antraquip roadheaders are typically used for tunneling (road, railroad, water, sewer) or in the mining industry. For the excavation of shafts, Antraquip suggests its roadheader based shaft sinking equipment provided the UCS of the material to be excavated does not exceed 8,000 psi.

Roadheaders offer a unique capability and flexibility for the excavation of soft to medium strength rock formations, therefore, are widely used in underground mining and tunneling operations. A critical issue in successful roadheader application is the ability to develop accurate and reliable estimates of machine production capacity and the associated bit costs.

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.

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.
