The selection of optimal method determining mechanical properties of coal layers
Abstract: The article presents selected methods and ways of mining resistance as well as mineability index determination with the use of different instruments. The principles of their operation and the way of mining resistance measurement as well as their usefulness in planning of cutting mining machines selection (longwall tumble heading machines) in given mining-geological conditions are discussed. Their advantages and disadvantages are presented and a method presenting actual mode of longwall tumble heading machines’ action is proposed. The results obtained with the use of this method should be taken as representative in the selection of cutting mining machines.
Key words: coal properties, analysis, the optimal method
