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 b...

Twelve of the numerous methodological problems are represented. They appear in the development of the automated systems for control of the mine works at open mines; if these problems are not reported the work of the system can be compromised partially of totally. Shortly those problems could be formulated as follows: 1.The mine is not considered like a system; 2.A management of the model; 3.Hierarchy of proposes and limitations; 4.The depot – a solution or a problem; 5.Attention: literally performance; 6.In prob...
