A New Generation of Portable Linear Rock Cutting Machine (PLCM ) and Comparison with Full Scale Linear Rock Cutting Tests
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 impossible to obtain. The core or rectangular block rock sample based cuttability tests are preferred in many cases. The PLCM is used for cutting small core samples or small block samples by a real-life miniscaled conical and disc cutters. The results are compared with the results ob-tained from full scale rock cutting tests using 17 inch disc cutter with 1.8 cm cutter tip width and full size conical cutters. It is found that there is close correlation between test results obtained from both cutting tests.
