SMALL SCALE LINEAR ROCK CUTTING TEST FOR CUTTABILITY ASSESSMENT OF UPPER RED SANDSTONE
Sajad Alimadi , Mining Engineering Department, Faculty of Engineering, Tarbiat Modares University, Tehran, IranAbstract
The cuttability of rock formations is a critical factor in optimizing mining and excavation processes, directly impacting the efficiency, safety, and cost-effectiveness of such operations. This study focuses on the cuttability assessment of Upper Red Sandstone using a Small-Scale Linear Rock Cutting Test (SSLRCT). The SSLRCT provides a controlled environment to simulate rock cutting and evaluate key parameters such as cutting force, specific energy, and tool wear.
Upper Red Sandstone samples were subjected to the SSLRCT under various conditions to measure these parameters and analyze their correlation with rock properties such as uniaxial compressive strength, density, and mineral composition. The results indicate that the specific energy required for cutting increases with rock strength and density, highlighting the importance of geological conditions in planning rock excavation operations. The study also explores the wear patterns on cutting tools, providing insights into tool life and replacement schedules.
