METHOD FOR FORECASTING GAS DYNAMICS INITIATION IN DRIVING DEVELOPMENT WORKINGS ON OUTBURST AND GAS BEARING SEAMS

摘要

FIELD: mining. SUBSTANCE: method includes drilling boreholes in coal block, measuring of coal fines output, initial rate of gas release along borehole length. Background methane concentration is measured additionally. Methane concentration in mine face is measured additionally. Methane concentration in working face just before working cycle initiation is admitted. EFFECT: higher accuracy in forecasting. 2 cl, 1 tbl
