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.
No tunneling blind spot technology Through field observation and measurement, the blind spot area account for % of the roadheader is operated by remote control and has a good operating field, which can reduce the operating blind area and the overcut section.
MT520 tunneling roadheader is a new concept of a construction roadheader in the 100 tons class, based on easily exchangeable modules, selectable to adapt the MT520 basic machine to a wide variety of appliions.

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 appliion is the ability to develop accurate and reliable estimates of machine production capacity and the associated bit costs.
The Roadheader from GMS German Mining Solution are divided into two machine types up to 40 tons: 300Series and 400Series ... The machines have been designed for both Tunneling and Mining for this appliion with Atex explosion protection. The 300Series with a cutting power of 100kW with a minimum vertical clearance of m is designed ...

Roadheaders are massive excavating machines fitted with a mounted cutting head which will mine out the caverns for both State Library and Town Hall stations. To better respond to the unique ground conditions in the, and to provide more spacious and accessible station platforms, an innovative trinocular design has been proposed for the State ...
Tunnel boring machines are fullface cutting machines, which means that, unlike road headers, they excavate the entire tunnel crosssection in one step. Source: Excavation of the roadheader for a parking garage under the Schlossberg Thun, Switzerland. TSM: Roadheaders belong to the egory of peripheral milling machines due ...
