| Abstract | The article deals with the selection of the composition of cement slurries for the construction of mine workings with concrete lining and high-precision segment lining. When using cement slurries to fill the space between the lining and the rock containing the mining output, the solution prepared from locally available materials may not meet the requirements, and the use of imported ready-mixed mixtures will be unacceptably expensive. Optimization of application modes of cement slurries in the construction of tunnels with a segment lining to increase the reliability of powerful and high-performance equipment. Systematization of the theory and practice of building tunnels with high-precision lining using mechanized tunneling complexes. Mathematical descriptions of the processes, experimental modeling of the obtained dependencies, and emergencies associated with the preparation of cement slurries are systematized. A description of the rheology of the cement slurry in the process of lining and the mechanism of the solution-rock mass system is given. The results of the experiment on the reinforcement of cement and lime cement slurries are given. The expediency of the solution reinforcement was confirmed not only for the formation of thixotropic properties but also for the maintenance of suspension. The results of a critical assessment of the components of cement slurries in relation to their use in mechanized tunnel complexes are given. The parameters for the preparation and use of mixtures should be selected on the basis of the results of comprehensive studies in specific conditions. The quality of preparation of the cement mixture in a complex increases the efficiency of the use of mechanized tunnel complexes. |
