METHOD FOR MONITORING AIR CONSUMPTION IN NETWORK OF MINES AND SYSTEM THEREFOR Russian patent published in 2016 - IPC E21F1/00 

FIELD: mining.

SUBSTANCE: invention can be used for rapid determination of air distribution in mine workings in standard and emergency modes of ventilation of mines. Method involves installation of air flow rate sensors in separate mine workings, which data are transmitted in real time to server. At that, air flow rate data transmitted from sensors in openings in channels of data transmission via controller to automated workstation of specialist, where with help of computer program calculates distribution of measured flow rate in all branches of ventilation system. Mine ventilation network aerodynamic model is installed on server containing network topology of mine workings, their aerodynamic resistance and location of ventilation units, wherein aerodynamic resistance of ventilation network branches is set on projected data both in case of data loss from one of fixed flow rate absence sensors, and by results of operating measurements. During operation of monitoring system efficiently solving task of distribution of air consumption in all branches of ventilation network based on model of ventilation and air flow sensors data, thereby forecasting consumption in all mine workings.

EFFECT: high information content and reliability of determining air flow rates in each production in mine workings.
