Open Pit Slope Design

Home | Services | Mining | Open Pit Slope Design

With our multidisciplinary approach and expertise in geotechnical engineering, we ensure the successful slope design and implementation of open cut mining projects. We work across the globe on projects from scoping level to detailed design phases, through to operational support, audits and mine closure. Our team of experienced professionals are dedicated to delivering innovative solutions tailored to meet the specific needs of each client.

Our approach

At PSM we understand that successful open cut mining ultimately relies on the knowledge and management of geotechnical risks. With our multidisciplinary approach to open pit mine slope design and management, we integrate geological, geotechnical, and hydrogeological considerations to develop innovative design based on sound practical approach.

The prime emphasis of services provided by PSM is on design, review and audit supported by appropriate modelling and analysis. Our fundamental tenet is that accurate engineering geological and hydrogeological models must be established for any analytical work to be meaningful. Even following detailed investigation and design studies, there remains uncertainty as to the likely performance of rock, soil and water.  Therefore, probabilistic and risk-based considerations are an important part of our design and review processes. 

OUR MAIN CAPABILITIES INCLUDE:

Site Investigations: We conduct detailed site investigations to gather critical data for pit slope design and analysis. This includes geological mapping, rock and soil characterisation, and ground water assessment.

Development of Accurate Geotechnical Models: Using advanced software and modelling techniques, we develop geotechnical models that provide valuable insights into slope stability and potential risks. The models also set out the key engineering parameters for the project.  Our wide engineering geology knowledge and project experience provides an invaluable resource in ensuring the "model is right".

Soil and Rock Engineering: Our expertise in soil and rock mechanics allows us to assess the properties and behaviour of different materials present in the mining area. This knowledge is critical  in the design of stable and safe pit slopes.

Stability Analyses and Slope Design: We perform appropriate stability analyses to assess the stability of pit slopes under various conditions. Based on these analyses, we develop optimised slope designs that maximise safety and productivity.

Assessment of Probability and Risk: Our team evaluates the probability and risk associated with slope failures, considering factors such as geological conditions, weather patterns, and mining operations. This enables us to implement effective risk management strategies.

Open Pit and Underground Void Interaction : Understanding the interaction between open pit mines and underground voids is crucial for ensuring the safety, stability, and economic viability of mining operations. PSM’s extensive experience in ground-structure interaction ensures that appropriate analysis tools are used.

Slope Management and Remediation: In the event of slope instability, we provide effective management and remediation solutions, including slope stabilisation techniques, monitoring recommendations and control measures.

Monitoring of Pit Slope: Our extensive experience in open pit slope behaviour and interpretation of monitoring data help in the early detection of slope movements, allowing for timely interventions and risk mitigation.

Design, Monitoring, and Remediation of Waste Dumps: The effective design, operation and maintenance of waste dumps is critical to efficient mining operations and mine closure considerations. We have undertaken the design of waste dumps across the globe and understand the importance of material characterisation, foundation conditions, hydrology and hydraulics on stability. .

Dewatering and Depressurisation of Pit Slope: We develop strategies for dewatering and depressurising pit slopes to improve their stability and facilitate safe mining operations.

Mine Infrastructure: Our geotechnical iservices extend to site investigations and foundation design for mine infrastructure . Our expert team provides services that include geotechnical site investigations, foundation assessments, haul road design, risk assessments and monitoring plans.

Pit slope management

A critical aspect of open pit mining is the monitoring and management of pit slopes. Our team is experienced in modern monitoring techniques and how to identify various failure mechanisms. We understand the importance of early detection in slope movements for safety and optimal slope management.

Rockfall is a key focus for geotechnical risk management and operational safety in the current mining environment. PSM have substantial experience in rockfall risk management, including conducting field trials, 2D and 3D modelling, development of qualatative 

Managing moving slopes is one of the most risk laden activities in open pit mining. At PSM, we understand that the stability of pit slopes is crucial for the safety and productivity of mining operations. Our experienced team employ advanced techniques to assess failure mechanisms, identify potential risks, and undertake appropriate slope stability analyses.

In the event of slope instability, our team provides expert remediation solutions to manage risk and retain productivity. We employ a range of techniques, including cutback design, reinforcement measures and drainage improvements, tailored to the specific site conditions.

Our engineers and engineering geologists have worked across the globe to deliver comprehensive strategic advice on geotechnical engineering and water for open cut mining projects of all sizes. While working alongside your organisation, PSM’s team of specialists can actively optimise the return on investment for your project by employing sophisticated technologies, current research and industry insights. From independent audits to design services, our open cut mining consultants offer a knowledgeable perspective that organisations can use to ensure safety and maximise outcomes for your site.
