world.
Concept of Geotechnical engineering & application in construction
Geotechnical engineering is the branch of civil engineering concerned with the engineering
behavior of earth materials. Geotechnical engineering is important in civil engineering, but also
has applications in military, mining, petroleum and other engineering disciplines that are
concerned with construction occurring on the surface or within the ground. Geotechnical
engineering uses principles of soil mechanics and rock mechanics to investigate subsurface
conditions and materials; determine the relevant physical/mechanical and chemical properties of
these materials; evaluate stability of natural slopes and man-made soil deposits; assess risks
posed by site conditions; design earthworks and structure foundations; and monitor site
conditions, earthwork and foundation construction.
A typical geotechnical engineering project begins with a review of project needs to define the
required material properties. Then follows a site investigation of soil, rock, fault distribution and
bedrock properties on and below an area of interest to determine their engineering properties
including how they will interact with, on or in a proposed construction. Site investigations are
needed to gain an understanding of the area in or on which the engineering will take place.
Investigations can include the assessment of the risk to humans, property and the environment
from natural hazards such as earthquakes, landslides, sinkholes, soil liquefaction, debris flows
and rock falls.
An engineer then determines and designs the type of foundations, earthworks, and/or pavement
sub grades required for t.

INTRODUCTION_AND_geotechnical_activities(2).pptx
Geotechnical engineering is concerned with engineering behavior of earth materials. It uses principles of soil and rock mechanics to investigate subsurface conditions, determine material properties, evaluate stability, assess risks, design foundations and earthworks, and monitor sites. A typical project involves reviewing needs, investigating the site through borings, laboratory testing, and assessing risks from natural hazards. Geotechnical engineers then design appropriate foundations and earthworks. Subsurface investigations characterize subsurface conditions and allow engineers to evaluate how earth will behave under structural loads.

Main objective of the executed researches was assessment of the strain-stress
condition of regional parts of pillar for definition of a possibility of formation of coal
congestions, prone to spontaneous ignition, in goafs of extraction longwall panels.
Analytical researches were carried out for the wide range of geological and mining
conditions of mining of flat coal seams by longwall. When performing researches
equations for definition of the strain-stress condition of regional parts of the coal
pillar were used. As a result of researches the sizes of zones of critical condition for
various conditions are determined and the conclusion is drawn on need of accounting
of a condition of regional parts of coal pillars for an exception of conditions for
emergence of the endogenous fires. The novelty of research consists in taking note of a
condition of regional parts of coal pillar and establishment of dependence of the
strain-stress condition of regional parts of coal pillars on the major mining-andgeological
factors.

GMEX Introduction
Dr. John McLellan established GMEX in 2012 to provide geomechanical modelling services to the mining industry. GMEX uses finite element and discrete element modelling techniques to better understand geological deformation events and fluid flow patterns to enable predictive mineral exploration targeting. These modelling techniques simulate crustal deformation and analyze resulting stress, strain, and fluid flow patterns to identify favorable areas for structurally-controlled mineral deposits. GMEX has successfully applied these methods in validation case studies to define new exploration targets at mines like Sunrise Dam and prioritize regional targets in areas like the Eastern Fold Belt in Mount Isa.

The role and importance of geotechnical engineering for a mining operation (1)
1. Geotechnical engineering has become an integral part of mining operations over the past few decades due to safety regulations and recognition of its value in optimizing mine design and managing risks.
2. Geotechnical engineers provide ground support to mining operations by designing stable pit slopes and underground excavations to maximize ore extraction while identifying design improvements or changes needed to address risks.
3. Continuous geotechnical data collection and analysis are needed to ensure mine design remains optimal as operations progress, and ground control risk management plans help prevent failures that can cause delays, shutdowns, or even mine closure.
Application of Drones for Mining Ooperations
Drones are increasingly being used in mining operations to help improve safety, efficiency and planning. They can conduct surveys of pits, stockpiles, tailings dams and other areas to produce 3D spatial data and maps. This data helps with tasks like short-term mine planning, production blast reconciliation, and monitoring geological or stability conditions. Drones allow remote access to hazardous or hard to reach areas, helping streamline workflows. While drone technology is advancing rapidly, their use in mining still faces some limitations from regulations, operating constraints, and the need for careful risk analysis when flying near equipment and personnel. As drones get smaller, cheaper and more integrated with autonomous systems, their applications in mining are expected to continue growing significantly.
MASc thesis: NUMERICAL MODELLING OF TIME DEPENDENT PORE PRESSURE RESPONSE IND...
This document presents a numerical modelling study of pore pressure changes induced during helical pile installation into fine-grained soil. The study uses the NorSandBiot modelling framework to simulate pile installation as a series of cavity expansions and contractions representing the helical pile shaft and helices. Model predictions are compared to field measurements of pore pressure during and after installation of test helical piles at a site in Surrey, BC with soft silty clay soil. The modelling aims to better understand pore pressure behavior observed in the field and provide a simplified technique for predicting stresses and pore pressures during and after helical pile installation.
Phd Thesis: Numerical modelling of surface subsidence associated with block c...
Through the use of an integrated FEM/DEM-DFN modelling technique this thesis presents a new approach to simulation of block caving induced surface subsidence allowing physically realistic simulation of subsidence development from caving initiation to final subsidence deformation. As part of the current research, a fundamental issue in modelling, the selection of representative equivalent continuum rock mass modelling parameters, is investigated and a procedure for calibration of modelling parameters devised. Utilizing a series of conceptual numerical experiments our fundamental understanding of the mechanisms and the role of the factors controlling block caving subsidence development is investigated. Valuable insights gained from this work are summarized in a preliminary subsidence classification and an influence assessment matrix of the governing factors. These are intended as an aid to engineering judgment for decision makers at the pre-feasibility and mine design stages.
This study also addresses one of the most challenging problems in mining rock engineering - the interaction between block cave mining and a large overlying open pit, focusing on caving induced step-path failure initialization. Using a novel approach to modelling data analysis a clear link between caving propagation, step-path failure development within the slope, and the resultant surface subsidence is established. In addition, FEM/DEM-DFN modelling is applied to the preliminary analysis of the block caving triggered slope failure at Palabora open pit.
This research represents a valuable contribution to block caving geomechanics and is a major step forward in the understanding of complex block caving subsidence phenomena, paving the way to more reliable assessment of caving induced subsidence deformations.
Role of rock mass fabric and faulting in the development of block caving indu...
Extraction of a large volume of ore during block caving can lead to the formation of significant surface subsidence. Current knowledge of the mechanisms that control subsidence development is limited as are our subsidence prediction capabilities. Mining experience suggests that, among other contributing factors, geological structures play a particularly important role in subsidence development. A conceptual modeling study has been undertaken to evaluate the significance of geological structure on surface subsidence. A hybrid finite/discrete element technique incorporating a coupled elasto-plastic fracture mechanics constitutive criterion is adopted; this allows physically realistic modeling of block caving through simulation of the transition from a continuum to a discontinuum. Numerical experiments presented emphasize the importance of joint orientation and fault location on mechanisms of subsidence development and the governing role of geological structure in defining the degree of surface subsidence asymmetry.
Numerical analysis of block caving induced instability in large open pit slopes
This paper addresses one of the most challenging problems in mining rock engineering - the interaction between block cave mining and a large overlying open pit. The FEM/DEM modelling approach was utilized in the analysis of block caving-induced step-path failure development in a large open pit slope. Analysis indicated that there is a threshold percentage of critical intact rock bridges along a step-path failure plane that may ensure stability of an open pit throughout caving operations. Transition from open pit to underground mining at Palabora mine presents an important example of a pit wall instability triggered by caving. Using combined FEM/DEM-DFN modelling it was possible to investigate the formation of a basal failure surface within an open pit slope as a direct result of cave mining. The modelling of Palabora highlighted the importance of rock mass tensile strength and its influence on caving-induced slope response.

Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

Hierarchical Digital Twin of a Naval Power System
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Geotechnical or Geomechanical?
- 1. 1 GEOTECHNICAL OR GEOMECHANICAL? Author: Dr. Alex Vyazmensky https://www.linkedin.com/in/vyazmensky/ Quite often, I hear a question: “Why the term Geotechnical Engineering is used in Mining?” Let’s investigate! There are five major specialty areas that deal with engineering in soil and/or rock: 1. Civil Geotechnics: design of foundations for urban construction and civil infrastructure, tunnels engineering, design of dams and large underground openings for civil applications (hydropower stations, nuclear storage facilities and etc.). 2. Engineering Geology: assessment and management of geohazards, forestry geotechnics, route selection for roads and pipelines, ground water management. 3. Mining Geomechanics: design of stable excavations and management of rock mass behavior under various stress conditions for the purpose of extraction of metals and minerals, input for selection of optimum mining method and its parameters, assessment of the extent of surface disturbance related to mining activities.
- 2. 2 4. Geoenvironmental Engineering: environment pollution management, landfill engineering and environmental reclamation. 5. Oil and Gas Geomechanics: wellbore stability and reservoir performance engineering. The boundaries between the first three specialties are blurred, given a largely common theoretical basis and a similarity of the problems solved (e.g. slope stability assessment for natural slopes vs. man-made slopes for road construction or open pit mining). Definition of Geotechnical Engineering continues to evolve, here is one which appears the most comprehensive: Geotechnical Engineering uses principles of Soil Mechanics, Rock Mechanics and Geology to: > investigate subsurface conditions and materials; > determine the relevant physical/mechanical properties of these materials; > evaluate stability of natural slopes, design stable man-made slopes and underground excavations; > assess risks posed by site conditions; > design earthworks and structure foundations; > and monitor and manage risks related to site conditions and earthworks. If we accept this definition, then Geomechanics and Geotechnics become interchangeable terms for Mining. As of now, major Mining companies by and large have adopted the term Geotechnical Engineering and the specialists practicing this discipline are referred to as (Mine) Geotechnical Engineers. It should be noted that the term Geotechnical Engineering is not universally accepted. In some countries/companies rock engineering specialists are referred to as Geomechanical Engineers, Rock Engineers, Strata Control Engineers and etc.
- 3. 3 A web search for Geomechanical Engineering jobs will lead to a major Oil and Gas operator or a reservoir engineering services provider. In the Oil and Gas Industry Geomechanics is becoming increasingly important (read more on this here). Rock and soil engineering specialities will continue to evolve, and, perhaps, in few years we will group them differently and under the new names! image source: LTU website
