EXTENDED PETRI NETS APPLICATIONS FOR MODELLING OF ROBOTIZED UNDERGROUND MINING PROCESSES

摘要

The main possibilities of Petri nets applications for underground mining are reviewed and presented. The suggested methods allow finding connections between practically important parameters of mining and Petri net terms. So, liveness corresponds with ability of long-wall performance recovering when failures are eliminated, reachable Petri net marking to influences the realisation of technological aim, safeness of Petri net marking corresponds to continuous coal flow. The creation of new models could be made simple and rapid by using different types of technological modules. Applying the Petri nets allows solving different problems in mining, which are difficult to investigate by traditional mathematical methods of modelling.
