Modelling of the stress-strain state of block rock mass of ore deposits during development by caving mining systems

Article preview

The article is devoted to the analysis of approaches to modeling the stress-strain state of a block rock mass in the vicinity of a single mine workings and in the area of rock cantilever influence during the development of the Khibiny apatite-nepheline deposits. The analysis of the existing in international engineering practice ideas about tectonic disturbances as a geomechanical element and the experience of predicting the stress-strain state of a block rock mass was carried out. On the basis of the analysis, the formulation of the basic modeling tasks is carried out and its main results are presented. Methodological recommendations for solving similar problems were developed.

The development of prediction method of earth-pressure balance and earth surface settlement during tunneling with mechanized tunnel boring machines

Article preview

The development of prediction method of earth surface settlement during the tunneling in heavy geological conditions of megalopolises was the purpose of the article.   The experimental-analytical and numerical prediction methods of earth surface settlement during tunneling by mechanized tunnel boring machines are proposed and justified.   The volume balance of earth surface settlement and volume of additionally excavated soil during tunneling are accepted as initial condition for experimental-analytical prediction method. The comparison of predicted and experimental data of earth surface settlement in different countries is performed. The prediction with numerical methods is produced in 3D with application of elastic-plastic soil body model. The matching of numerical calculations data and data of experiments and analytical calculation is revealed. The proposed prediction methods may be used for geotechnical substantiation of projects of tunneling in heavy geological conditions.

The prediction technics of tunnel sets with complex three dimensional configuration stress state with allowance for relative influence and building sequence

Article preview

The three dimensional stress distribution in tunnel set with allowance for relative influence and building sequence is investigated. To complete the task the finite  elements analysis was  used. The values of stress concentration factor and conformities of stress distribution in the «lining – mass» system are estimated. The relative influence of each tunnel in tunnel set with allowance for building sequence is identified.

The designing of the constructions of the pillar underground station with applying of the low-settle building technology

Article preview

The intelligent technology of designing of the constructions of pillar  underground  station is adduced. Station is building with applying of low-settle technology, which takes into consideration main stages of the building process. The scheme of interaction of the system «support lining-soil massif» was accepted as basic scheme of calculations. The calculations of the stress-strain condition of constructions was performed with applying of finite-elements method.

The determination of the volume stress-strain conditions of the soil massif in the face area of the tunnel in conditions of drafting with using of contledge of the face

Article preview

In this learned article the analysis of reinforcing effect, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in tunnel boring machines, is adduced. By applying of the finite-elements method the family of graphical relations, which reflects the processes of the development of displacements, is approached. For the reason of analysis of these relations the optimal value of contledge of the face if maximum permissible displacements of the earth surface are known have been suggested. The influence of the main strength characteristics of Couloumb – Mohrs’s theory of strength on stability of the face of the tunnel and the necessary value of contledge of the tunnel’s face are defined.

Article preview

The article presents the rationale of temporary supports used in the drilling of new mines, which provides for the construction of model projects of reconstruction of old tunnels. Finite-element method analyzed the changes of stress-strain state containing tunnel complex array during the drilling of new mines. Based on the analysis, a number of findings to explore the possibility of reducing the thickness of the permanent support of new mines in tunnel complex - the new tunnel, and transport and drainage culvert.
