Excavation Mec.&Natural Stone Tech.

EXCAVATION MECHANICS LABORATORY

Excavation mechanics is a rapidly evolving science interested with the selection of the cutter and the excavation machine types and the prediction of the selected machine's performance according to excavation process to be made in different types of rocks.  The performance analyses of the excavation, cutting and the drilling machines used in the mining and construction sector and the optimum working conditions depend on the studied rock properties are performed through both for graduate and undergraduate researches as well as industrial applications in our laboratory.

 

The equipment located in the laboratory is as follows;

*  Laboratory scale drilling test device

*  Laboratory scale cutting test device 

*  Impact strength apparatus in various sizes

*  Hardness (Shore A , Mohs and Schmidt ) measurement

*  RIHN test

*  CRS test

*  Peshalov test
