Prediction of the stress-strain state and stability of the front of tunnel face at the intersection of disturbed zones of the soil mass

Article preview

The article presents a numerical solution of the spatial elastic-plastic problem of determining the stability of the tunnel face soils at the intersection of disturbed zones of the soil mass. The relevance of the study is related to the need to take into account the zones of disturbed soils when assessing the face stability to calculate the parameters of the support. Based on the finite element method implemented in the PLAXIS 3D software package, the construction of a finite element system "soil mass-disturbance-face support" and modeling of the intersection of the disturbed zones of the soil mass were performed. To assess the condition of soils, deformation and strength criteria are taken. The deformation criterion is expressed by the value of the calculated displacement of the tunnel contour in the face, and the strength criterion - by the safety coefficient until the maximum values of the stress state are reached according to the Coulomb–Mohr criterion. The results of the study are presented in the form of histograms of the safety coefficient dependences on the distance to the disturbance at different bending stiffness of the face support structure, as well as the isofields of deformation development. The parameters of rockfall formation in the face zone at the intersection of zones of disturbed soils were determined. The local decrease in strength and deformation properties in the rock mass along the tunnel track should be taken into account when assessing the stability of the tunnel face and calculating the parameters of the support. Within the framework of the constructed closed system, a qualitative agreement of the simulation results with the case of a collapse in the face during the construction of the Vladimirskaya-2 station of the St. Petersburg Metro was obtained.

Modeling of geomechanical processes in ore mass using physically nonlinear model

Article preview

The aim of the article is to develop a method of forecasting the state of stress of the ore mass around excavations for ores of weak and medium strength. The paper presents experimental studies on the deformation of ore samples of low and medium strength in the forging equipment in conditions of volume stress state. A physically nonlinear model is used to describe the deformation process of ore mass. The study of the stress state of physically nonlinear ore mass around excavations of round and valuated cross-sections is performed. Values of coefficients of tangential stress concentrations on excavation contour are found for different types of ore. Solutions to physically nonlinear problems in preparatory excavations in the development of the Yakovlevskiy deposit of rich iron ore using a slicing method are considered. Methods for forecasting the stress state in rock mass around mine excavations can be used to assess their stability in the mining of ore of low and medium strength at the Yakovlevskiy iron ore deposit and in the rock and soil masses.

Problems of development of raw material base of aluminum industry of Russia and organization of production in conditions of market economy

Article preview

The main ore base of the Russian aluminum industry is the deposits of the North Urals bauxite basin. The deposits are developed at depths of 900-1000 meters, and the design and opening of new horizons is planned at depths of 1500-2000 meters. The mining and geological conditions of deposit development become sharply more complicated at greater depths. To ensure the required volumes of bauxite production under such conditions, it is necessary to solve the problem of safe mining operations at deep horizons of mines.

Earthquake-proof structures of mine workings during the development of shock-hazardous deposits

Article preview

On the basis of the laws of changing the parameters of the dynamic stress field during the interaction of seismic waves with the mine workings the requirements to the seismic resistant armoring of mine workings in the zones of rock bumps and mass explosions are formulated. The operability of traditional types of anchors under dynamic loads is evaluated. The optimum design of fortification of excavations in the shock-hazardous areas is a combined support from steel-polymer or reinforced concrete anchors with a solid filling of the boreholes with a fortifying composition enhanced by piles of long (up to 3.5 m) reinforced concrete anchors in the place of wave exit on the contour of the excavation. The length of the anchors is chosen according to the tensile stress zone overlap.

Problems of developing deep deposits of rich KMA iron ores

Article preview

On the example of Mikhailovsky and Yakovlevsky deposits the problems of development of rich iron ores of KMA related to their deep occurrence, taking into account difficult engineering-geological conditions of construction of underground mines and harmful consequences of ore mining by open pit for the natural environment are considered. The results of complex tests of physical-mechanical properties of loose rich ores, which have not been sufficiently studied yet, are presented. Forecast of land alienation and soil contamination caused by an increase in the volume of overburden during further exploitation of Mikhailovsky open pit is given. For the Yakovlevsky mine, the most effective layered systems of development of the ore body with stowing of the mined-out space were studied. The descending order of mining of blocks with the device on the top layer of protective overlap to prevent subsidence of the overlying strata with the formation of channels of hydraulic connection with the coal aquifer is recommended.

Regularities of mine workings deformation at dynamic forms of rock pressure manifestations

Article preview

Field observations of the displacement of rocks around the preparatory and cleaning workings (operations) of SUBR mines (shafts) establish the effect of stratification of the roof of workings (operations) and cleaning chambers under the action of seismic waves. The shifts are traced to a depth of up to 4 m, and almost instantaneously, at the moment of the rock impact. When modeling the process of interaction of a flat straight wave with workings (production) of rectangular, vaulted and shapes of cross-section, it is shown that the probability of reaching the limit state of the host rocks due to the maximum difference in the main pressure (stress) is higher in workings (production) of rectangular and more shapes. Based on the revealed dynamics (changes) of seismic pressure (stress) and regularities of deformation of the host rocks, the design of reinforcement (strengthening) of the roof of chambers and joints of excavations (workings) with deep reinforced concrete anchors was developed.

Use of underground space to improve safety and environmental friendliness of nuclear power plants

Article preview

One of the drastic measures to increase environmental safety and safety in operation of nuclear power plants is to use underground space for their location. Operating experience of underground nuclear power plants (UNPP) has shown high levels of their safety and reliability of the reactor and processing equipment as well as environmental protection. The rise in UNPP safety is secured by the rock massif strength, its insignificant penetration properties, reactor opening impermeability and system of gas gathering and outgassing through lining and drainage. To reduce long-term exposure of the walls of the reactor opening to high temperatures in case of a failure, a water sprinkling system is provided. In case of an emergency increase in pressure in the reactor opening, the gas-vapour mixture will pass through the rack massif and, due to its low temperature, gas condensation will occur and the wave front propagation will decrease in speed. Quantitative assessment of security arrangement demonstrates that the highest level of security is achieved at UNPPs with double casing and UNPPs with pressure release. One of the drawbacks of UNPPs is an increase in their cost and construction time. According to various estimates, the increase in the cost of UNPP construction relative to the construction of a land-based NPP is 15-25%, and the construction period increases by 1.5-2.5 years. An effective way of reducing construction costs for UNPP is to combine it with burial grounds for radioactive waste, that are adopted for recycling and storing waste both produced by the UNPP and brought from other nuclear enterprises of the region.

Causes of rock deformations on the contours of mine workings under the action of blast waves

Article preview

Blast wave influence on rock stability in mine openings is given an account of. Results of mathematical modelling of a dynamic stress field created in the massif due to wave interaction with the mine opening have been analysed. A stress field influenced by short wave blasts has been studied. Equations of dynamic balance for theoretically elastic environment, supplemented with boundary and initial conditions for the corresponding components of stress tensor, serve as the basis of a mathematical model developed by V.V. Karpenko and G.A. KoIton. The set of 5 equations was solved using S.K. Godunov numerical technique. Input data are assumed on the basis of the mining conditions at the Severniy (Northern) mine (blast hole diameter - 76 mm; blast type - granulite AC-8). A particular case of blast influence at 10 m range between the charge and the gallery roof (r =370) has been studied. Distribution diagram parameters of the forward-moving elastic wave compression phase have been determined using analytical dependence for a cylinder-shaped charge blast (amplitude σ o = 9.6 MPa, period of time t - 1.2 ms, speed C 1 - 4500 m/s). It has been demonstrated, that form the direction of the forward-moving wave, refracted and diffracted waves create in the massif an extensive zone of radial tension stress, peaking at 1.6 at the distance of 0.8-1.0 R from the contour. In lateral areas, the blast wave produces concentration of tangential compression stresses up to 1.6 σ o . An estimation of mine destruction caused by the energy of dynamic development has been given. Besides dynamic compression and tension stresses, repeated blasts and impulse stress load and relief on the massif also influence stability of the mine openings. An estimation of rock stability criteria at the entry contour during joint action of static and dynamic stresses has also been given.
