Stability Analysis

The software system is designed to assess stability of open pit benches and walls, as well as dump lifts in homogeneous, quasihomogeneous and heterogeneous rock mass.

Stability Analysis
Main Feature

Simulating preparation of geomechanical state on the grounds of the evidence base on mining and geological terms of deposit and rock mass

Assessment of the actual state of the pit edges and dumps on different sections of the pit walls

Graph-analytic, geomechanical calculations of sustainability assessment of the current state of the rock mass

Development of the computational models of:

maximum permissible angles of the ledge slopes and the pit wall inclinations (with random width interval of positioning of the tested cambers)

geomechanical conditions and state of the rock mass

assurance factor for current mining and geological conditions

Methodology as the basis of the work

Constructing schemes of the width and sliding surface of the prism of the eventual failure for the estimation of the degree of stability of the ledges and sections of the temporarily non-working pit edges as well as steady state of ledges and sections of the pit edges according to the mathematical and vector composition of forces

Deformation schemes of the near edge dumps on the weak base of different capacity

Computational sustainability schemes of the ledge slopes and the pit edge inclinations and dumps.

Study of chemical composition and physical and mechanical properties

Processing tests of rocks’ strength,shift,compression, layering, cleavage, porosity, lumpiness, dislodgement, solidness, abrasivity, etc.

Research of mining and geological conditions and modeling

Modeling of terrain surface and properties of overburden rocks, strength of the mineral bodies, presence of tectonic disturbances and surface weakness zones, consideration of region seismicity and other factors that lay the foundations of the model development

Calculation methods

Method of algebraic addition of forces

With foundation uplift (on loose powerful base)

Force polygon method for homogeneous environment

Force polygon method for homogeneous environment

Geological and structural mapping of the rock mass

Visual observation of ledge slopes, photographing of the sections of the slopes and pit walls, description of stratifications and fracturing, morphological determination of geological bodies, measurements of fracturing, recording of data for the development of the models for the geomechanical condition of the rock mass.

Reconstruction of the fracturing systems of various masses for the developed models.

Computation of sustainability

Estimation of sustainability of the ledges, pit edges and the dumps in homogeneous,quasi homogeneous and heterogeneous rock masses
