Investigation of the deformation characteristics of water-saturated coal samples with a hole for estimating the discharge of the reservoir during hydrolysis

Investigation of the deformation characteristics of water-saturated coal samples with a hole for estimating the discharge of the reservoir during hydrolysis

The deformation characteristics of the uniaxial compression of the same sample with a central hole at different humidity are presented. The sample was saturated with water under pressure through the hole. The deformation curve has the form of a one-term power dependence. Increasing the humidity by 2...
