FIELD: controllable methane extraction from coal beds.
SUBSTANCE: method involves measuring methane concentration at different distances from well and at different ground depths with the use of gas sampling pipe; determining coal-methane hole efficiency from measured methane concentration before and after hydraulic fracturing of coal bed.
EFFECT: possibility of indirectly efficiency estimation.
