METHOD TO PROCESS INFORMATION ON CONCENTRATION OF METHANE IN DEVELOPING ENTRY Russian patent published in 2014 - IPC E21F7/00 

FIELD: mining.

SUBSTANCE: invention relates to current forecast of methane release into developing entries and may find wide application during automated current forecast of methane-bearing capacity as linked to data of remote supervision of content in an entry. The method is proposed to process remote measurements of methane concentration for current forecast of air flow during entry ventilation, including separate definition of methane concentration in periods of combine operation and with absence of coal extraction with a conveyor being unloaded. The current forecast is carried out on the basis of measurements of dynamics of methane concentration and air flow for ventilation of the mine with account of mathematical dependence including actual air flows during measurements of methane concentration and coefficients of proportionality of methane release by sources for actual and design lengths of the entry.

EFFECT: increased validity of air flow forecast for ventilation of an entry as its length increases.
