In the surface mining industry, the Equipment Selection Problem involves choosing an appropriate fleet of trucks and loaders such that the long-term mine plan can be satisfied. An important characteristic for multi-location (multi-location and multi-dumpsite) mines is that the underlying problem is a multi-commodity flow problem. The problem is therefore at least as difficult as the fixed-charg...

Abstract The paper deals with theoretical bases of the implementation in mining equipment design up-to-date methods using modelling and simulation, supported by examples personal research. This has become necessary due to structural complexity this equipment, variety aggressiveness their operating environment. presented refer different kinds used mechanical extraction mineral raw materials, fro...

The aim of this paper is to examine the ergonomic hazards associated with small scale mining in Southern Africa. A number of ergonomic health hazards affect the workers involved in the small scale mining. Many people in Southern Africa are working in the informal mining sector without any guarantee of occupational health and safety. Actual work places in deep level mines present unique challeng...

The work analyzes current technologies of ore mining applying self-propelled equipment in underground conditions; studies practices using the general and for broken transportation only; considers performance enterprises similar mining-geological miningtechnical generalizes causes high loss dilution rates Kryvyi Rih iron basin, thus revealing a problem providing efficiency increased extraction w...

With the development of complex and intelligent sizeable mechanical equipment, conflict between maintenance production is becoming increasingly severe, restricting coal mine enterprises' development. This paper proposes a joint decision-making model for planning fully mechanized mining equipment to solve maintenance. Taking as research object minimizing total cost objective, we use Hybrid Genet...
