A New Generation of Portable Linear Rock Cutting Machine (PLCM ) and Comparison with Full Scale Linear Rock Cutting...
Abstract: A new portable linear rock cutting (PLCM) device was developed in the Mining Engineering De-partment of Istanbul Technical University and supported by The Scientific and Technological Re-search Council of Turkey (TUBITAK-112M859). The basic disadvantage of the full-scale linear rock cutting test is that it requires large blocks of rock samples, which are usually difficult, too expen-sive, or...

Analysis of the Tunnel Boring Machines (TBM) Performance Parameters Using Boreability Index in Turkey
Abstract: Performance prediction and the determination of some design parameters of TBMs are becoming very crucial for tunneling industry since they are critical elements in the pre-planning of a mechanical excavation project. In this paper three case studies are analyzed with a detailed field and laboratory studies concerning in Istanbul. The performance parameters of the TBMs (Cutter forces, i.e.,...

Cutter Forces Measurement with (PLCM ) Comparison with the Theoretical Models
Abstract: Proper machine and cutter selection, cutter head design and performance prediction for mechanized excavators such as TBM or roadheaders are the most important parameters for a mechanized tunnelling or mining project. The most used machine design parameters are cutter layouts, cutting power of the machine, torque and thrust. Besides, performance prediction of the machines can be done by...

Cutter Forces Measurement with PLCM© Using Mini Conical Pick: Comparison with the Theoretical and Empirical Models
Abstract: A new portable linear rock cutting (PLCM©) device was developed in the Mining Engineering Department of Istanbul Technical University and supported by The Scientific and Technological Research Council of Turkey (TUBITAK-112M859). In this paper, rock cutting experiments are performed by using mini real-life conical pick with a (PLCM). The conical pick used in this study has an attack angle 45...

TBM performance prediction using PLCM and comparison with TBM field performance parameters
Abstract: Full Scale Linear Cutting Machine (FLCM) is a most popular rock cutting test device for prediction performance parameters of mechanical excavators. LCM test have some disadvantages that requires too much manpower, large blocks of rock samples, which are usually difficult, too expensive, or impossible to obtain. For these reasons a new portable linear rock cutting...

Unrelieved Spesific Energy Estimation from PLCM and FLCM Linear Rock Cutting Tests and Comparison with Rock Properties
Abstract: Estimation of laboratory specific energy values from mechanical rock properties to predict the efficiency of mechanical miners (tunnel boring machines, roadheaders, continuous miners, shearers, etc.) is the basic aim of this study using laboratory linear rock cutting devices. Specific energy is defined as the amount of energy required to break a unit volume or weight of rock expressed in kWh/m3...
