Abstract
The article considers the developed unit for investigations of interaction between coal and gas, and gas outflow from the coal surface by gravimetric method under gas pressure up to 6 MPa. Relationship between the sorption ability and metamorphism stage is explained by the microstructure of coal. The adsorption increment indices of volume V and velocity of changes in pressure P – during adsorption may be used for prediction of outburst-hazard of coal and gas.
