  • Numerical simulation of quarry wall stability considering the fault location in the bottom part
    Asangiz Moldabayev, Dmytro Babets, Serik Moldabayev, Olena Sdvyzhkova, Atac Bascetin, et al.
    Mining of Mineral Deposits, 2026
    Purpose. The research aims to assess the impact of geological disturbances located in the bottom part of the super-deep Kacharsky Ore Quarry on the stress-strain state (SSS) of its walls and to determine the safety factor of the walls, taking into account the complex geological situation. Methods. Fault plane modelling methodology is based on 3D finite-element analysis using the RS3 Rocscience software. Fault zone is represented by a medium with a system of fractures. Fracture characteristics, such as openness, contact filler type, and surface quality are achieved by selecting the normal and shear stiffness of the contact. The strength and deformation properties of rock inside the fault zone are defined by low geological index values (GSI = 20), corresponding to the “poor” quality mass according to the Hoek-Brown classification. The main mass outside the fault zone is represented by elastic-plastic medium, where the transition to inelastic deformation stage is determined by the Mohr-Coulomb failure criterion. Findings. FEM-analysis of the stress-strain state of the Kacharsky quarry walls at various stages of mining, taking into account faults in its bottom part, provides a safety factor (FoS) that is 28-30% lower than that obtained without considering the faults. Parametric analysis shows that for normal stiffness values of the fracture-filling material up to 2.5 GPa/m, the difference in the realized shear strains is most significant. When the Er index, which characterizes the ratio of material stiffness inside and outside the fault zone, decreases from Er = 0.2 to Er = 0.05, the maximum shear strains in the bottom part of the quarry increase from 0.05 to 0.075, that is, by 50%. Thus, a weaker and more disintegrated medium in the fault zone provokes the development of shear strains and causes a decrease in the stability of the walls. Originality. For the first time, under real mining-geological conditions of deep ore quarry, a pattern of change in safety factor of steeply sloping walls has been identified, taking into account geological faults in the bottom part of the quarry. A dependence of shear strains on the normal stiffness index of fractures and the ratio of stress-strain modules of the rock medium inside and outside the fault zone has been found. Practical implications. The wall safety factor (FoS) value at each stage of mining is a key parameter for adoption of technological decisions and regulations. The established fact that the stability of the walls has decreased to a critical level (FoS = 1.1) at the final stage of mining due to the presence of faults may serve as a basis for revising the technological scheme of ore mining at the final stage, in particular, to reduce the slope angle of the benches.

  • FEATURES OF OPTIMIZING THE CALENDAR SCHEDULE OF OPEN-PIT MINING BY STEEPLY INCLINED LAYERS
    Serik Moldabayev, Zhanat Sultanbekova, Madiyar Sarybayev, Tolegen Adil, Madinur Akhmetova
    International Multidisciplinary Scientific Geoconference Surveying Geology and Mining Ecology Management Sgem, 2022
    The transition to mining benches with transverse panels from top to bottom within the boundaries of steeply inclined layers does not allow transforming the results of mininggeometric analysis sequentially for each individual stage of mining into a calendar schedule of mining operations. Therefore, a model is offered for converting the results of mining-geometric analysis into a calendar schedule of mining operations with sequential mining of benches from top to bottom using phased volumes of overburden rocks and ore reserves of adjacent steeply inclined layers. Each next stage of mining includes ore reserves of the previous steeply inclined layer and volumes of overburden rocks of the adjacent steeply inclined layer. In this case, the time of simultaneous mining of ore reserves and overburden in adjacent steeply inclined layers is assumed to be equal and should ensure the fulfillment of the annual design volumes of ore extraction. A reduction of overburden excavation, due to a significant increase in the slope angle of the pit walls of the steeply inclined layers, is achieved with the provision of independent high-rhythmic overburden and mining operations even on round shaped open pit fields. The studied technology of mining benches transverse panels in steeply inclined layers below the thickness of loose overburden rocks could improve technological development of deep and ultra-deep open pit mines, especially with combined motor-conveyor transport. Optimization of the calendar schedule of mining operations when mining rock overburden and ore with transverse panels in steeply inclined layers was performed at the ultra-deep Kacharsky open pit mine.

    Purpose. To establish the feasibility of refining deep open-pit mines below the boundary of the use of combined motor-conveyor transport with an increased slope angles of the pit walls using the developed transport unit for reloading rocks to overlying horizons during the reactivation of pillars under transport berms. Methodology. Preparation of a digital block model of the deposit, the elaboration of 3D geomechanical models for the dynamics of mining, 2D and 3D numerical simulation of the rock stress-strain state of the outcrops of opencast workings, mathematical modeling of stepwise ore reserves and mining schedule, patent research and feasibility study. Findings. It is advisable to carry out mining in terms of the marginal rock state with an increase in the slope of the pit sides below the limit of application of the cyclic and continuous method in ultra-deep open pits. Such design of pit sides is achieved when benches are mined from top to bottom within the boundaries of steeply inclined layers with the use of inter-bench loaders of the developed designed in the completion zone. Provisions for the selection and feasibility of using the loader in the deep zone are formulated based on demarcation of application zones of cyclic (road transport) and cyclic-flow (combined road-conveyor transport) technologies. Originality. Schematization of the mining operation was performed based on the calculated values of safety factor of sides, which allows increasing the slope angles of the pit walls of even ultra-deep open pits in the completion zone. It was found that with deepening of mining, the zones of potential sliding move away from the loose overburden to lower ore benches closer to the final depth of the Kacharsky open pit (760 m), but the safety factor corresponds to the required value according to the design standards. Practical value. An increase in the slope of the pit walls in the completion zone can be achieved using the developed loading installation, the main difference of which is that it can be moved without dismantling under conditions of reactivation of transport pillars (with an increase in lifting height by 1.54.5 times compared to the known equipment).
  • Probabilistic assessment of slope stability at ore mining with steep layers in deep open pits
    Olena Sdvyzhkova, Serik Moldabayev, Atac Bascetin, Dmytro Babets, Erzhan Kuldeyev, et al.
    Mining of Mineral Deposits, 2022
    Purpose. A methodology development for predicting the geomechanical situation when mining an ore deposit with steep-dipping layers, taking into account the uncertainty in determining the rock properties, which is a consequence of the rock mass heterogeneity. Methods. The assessment of the open-pit wall stability is based on a combination of numerical simulation of the rock stress-strain state (SSS) and probabilistic analysis. The finite element method is used to determine the changes in the SSS that occur at various stages of mining operations due to design changes in the overall open-pit slope angle. The elastic-plastic model of the medium and the Mohr-Coulomb failure criterion are implemented in the codes of the 3D finite element analysis program RS3 (Rocscience). Stochastic simulation is used to assess random risks associated with natural object state variations. Findings. The distribution of maximum shear strains, which localizes the real or potential sliding surfaces in the open-pit wall at various stages of ore mining, has been identified. Based on the Shear Strength Reduction procedure, the open-pit wall Strength Reduction Factor (SRF) has been determined. The probabilities of open-pit wall stability loss, as well as the decrease in the strength reduction factor below the standard level at all stages of the ore body mining, have been revealed. Originality. For the first time, for real mining-geological conditions of a deep ore open pit, the dependence of the strength reduction factor on the overall wall slope angle, which changes during mining of each steep layer, has been determined. For each stage of mining operations, for the first time, the probability of a decrease in the open-pit wall stability below the standard level has been determined based on stochastic simulation. Practical implications. The ratio between the open-pit contour characteristic (overall slope angle) and the probabilistic safety factor is the basis for practical solutions to ensure the efficiency and safety of mining at various stages of friable and hard overburden excavation, ore extraction, as well as for the subsequent optimization of the open-pit design contours.

    E3s Web of Conferences, 2019
    A 3D model of optimal contours phased development of oval-shaped open pit mines is proposed in the article. It is assumed that with enough accuracy the volumetric contour of the open pit mine is interpolated by an elongated elliptic hyperboloid. The calculation formulas for mineral resources are derived and optimal volumes of overburden are determined depending on the mining phase. In this case, the total number of mining phases is set in advance. The stripping ratio is used as a quality criterion of the optimization task. The problem of optimal control is solved using the Bellman function in dynamic programming. All the necessary calculation formulas are obtained in the final form by solving the optimization problem. Their simplicity and substantiation of each conclusion ensure that the results of this study can be successfully applied in practical calculations of the design and planning of mining operations in open pit mining.
