ABSTRACT

The optimization of the coal winning process using different mechanical and alternative
cutting techniques using appropried mathematical models is an up to date reserch
methodology. In the paper, two kind of such models are presented, first using deterministic
analytical relations evaluated by numerical calculus, and the second using Monte-Carlo
simulation of the process using experimentally obtained test data to generate random values
of intrinsic rock parameters and logic diagram for the functional connections between
winning machine element. Both models are useful for the assessment of the winning
productivity, influence of bit wear on it, energy consumption and effectiveness of the winning
process in different mining conditions.
