The transport represents one of the main sides of the mining technological process, the preponderance of the expenses of this activity reported to the expenses for producing a tone of useful mineral substance extracted from the underground reaching almost 40\%. A good transport system presumes to assure a permanent continuity with passive time cycles having minimum values and functioning in well correlated cascade dimensionally and capacitive speaking. It’s obvious that a transport flow is performing if starting...

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...
