Abstract: In article the algorithm of calculation of gas methane emission out from loose and transported coal on the basis of modern representations about properties and conditions of coal- and- methane layer is resulted. Possibility of definition of maximum permissible speed of the extracting combine movement for an exception of methane concentration excess of an air flow is shown.
Key words: coal layer production face combine gas methane emission transportation time
