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...

| Summary: | 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 % reduces axial stresses by 3.2 times, and the modulus of elasticity - by 2.5 times with the same deformation. |
