Popis: | Features of the change in strength and deformation properties of coal during the action of adsorption-active media, especially under the conditions of a complex stress state, are not always evident and, consequently, cannot be taken adequately into account when performing work utilizing the physicochemical treatment of rock masses and coal in order to increase the safety and efficiency of mining production processes. Taking into account the importance of such data for intensification of the change in properties and state of the host rock during mining, including even finding the optimal conditions for coal destruction, they studied the singularities of adsorption-active fluid interaction with coal under complex stress state conditions. The deformation curves for brown coal and coal of grade T obtained under simple uniaxial compression conditions are represented. |
