Statistical dynamics-based estimation of ventilation control in coal mines

Mine ventilation is intended to ensure sufficient air flow rates in working areas at any time to assure safe and normal duty of mining processes. Mine ventilation control consists in design and implementation of long-term (one-time) arrangements for the stable topology and gas dynamics conditions, and for the quick-look re-distribution of air flows in ventilation network branches subject to deviation of test parameters of mine air from the technologybased standards of mine safety and operational regulations. This research aims to analyze and estimate aerodynamic parameters of air distribution control in coal mines. The research uses the methods of statistical dynamics, correlation functions of random variables, theory of sets, basic laws of mine air dynamics, theory of graphs and discrete mathematics. A proper choice of the method to determine dynamic characteristics using the normal duty data requires checking additivity of gas-dynamic processes, i.e., it is required to find out whether the gas-dynamic processes contain components which give rise to correlation function tails. An approach is proposed to the air distribution control improvement in mine roadways with regard to ventilation network details.
