Abstract

Generally, determination of suitable block size, is one of the most essential factor for optimum and economic excavation. In mining ornamental stones by DIAMOND WIRE it must be such that it does not cause any problems with regard to excavation sequences, be safe and also reduce the costs. This paper presents the results of an investigation which was carried out in LAYBID ornamental stone mine. The aim of this research, was to determine the OPTIMUM BLOCK SIZE with regard to geological and geotechnical conditions and machinary used in this mine. The method has a general trend which can then be applied to any mine with similar excavation method by considering the special conditions of that mine. The OPTIMUM BLOCK SIZE is determined by calculating operation costs such as excavation, cutting, etc. These calculations were carried out for various block sizes and various graphs plotted. In this mine the OPTIMUM BLOCK SIZE was determined to be 6x4.5x8 meters for length, width and height of the block respectively. The increase in block dimentions and suitable block dimentions with regard to the main block is an important factor for cost reduction. This procedure will be acceptable up to a point where excavation costs decrease greatly and also no technical problems occur.
