Selection of ore transport system for a metalliferous underground mine / Dobór systemu transportu rud w kopalni podziemnej rud metalu

Abstract

The conditions of increasing competition in today’s mining industry, deepening of mines and also decreasing ore reserve and quality parameters (grade, calorie, ppm, etc.) compels to reduce unit cost for maximum benefit. In this context, optimization of machinery and equipment in technical and economical sense is required in terms of economic mining. In underground mining, as ore transport operation significantly affects profitability, optimization of the system gains importance technically and economically. In this paper, the authors studied production capacities up to 1,000,000 ton/year and orebody depths up to 1,000 m according to different haulage systems; conventional shaft hoisting, declined mine truck haulage and flexowell vertical belt applications. In model study, unit transport costs of each alternative depending on the production capacity and mine depth have been calculated.
