Design and Mechanical Behavior of a Custom Adapter for Dimensional Stone Mining

Abstract

The paper deals with the development of a dimensional rock sawing machine to optimize the production of small-volume dimensional stone products in limestone quarries by re-thinking the use of production and transport equipment. A low-volume mining production and transportation adapter to be developed for both production and transport can reduce the number of mining machines to be used in the mine. After cutting around the block stone, the rock material can be moved with the help of the machine. Cutting tests were performed to determine the winning properties of the limestone. The first objective of the paper was to calculate the cutting forces and cutting powers and eliminate the failure possibilities and vibrations. In this study, the eigenvalue extraction used to calculate the natural frequencies and mode shapes was based on the Lanczos iteration methods using the Abaqus software to identify any potentially dangerous frequencies. By taking the load cases from modelling of the extraction of limestone and the transport of block stones, the deformation and strength properties of the adapter were also examined using FE analysis for stress/displacement analysis. Drawing the conclusion from finite element analysis, the construction of the adapter can be developed and checked. The results can be used with great confidence, so the main dimensions of the concept serve as the basis for the dimensions of the adapter.
