Selecting the ‘Optimum’ Pit”
Selecting the optimum pit shell as the basis for design is often not as straightforward as it appears, with a number of pitfalls for the unwary. This discussion covers aspects related to risk and return, the ‘hill of value’, value and size plateaux, incremental and average strip ratios, inflexions in value versus shell size. The process is not simply the case of selecting the optimum value shell. The choice inherently involves consideration of corporate objectives, risk minimisation, variance on translation to design, optimising value and/or mine life and leaving open optionality for future exploration and underground development. Case study examples will be highlighted that illustrate what to do and what not to do.

“Sorting the Chaff from the Wheat – Mining Dilution and Loss – Misconceptions, Miscalculations and Lies”
Mining projects often assume nominal or benchmark estimates for dilution and loss that turn out to be quite different in practice, often obscured by either a lack or inaccuracy in mine reconciliation. This discussion focuses on some of the modern techniques adopted for more reliable evaluation of these modifying factors, supported by case study examples. It will cover a variety of aspects including techniques; industry benchmarks; halo and mixing zones; block regularisation and the selective mining unit (SMU); equipment size considerations; ore contact surface roughness/amplitude; mining accuracy; orebody dip/geometry, continuity, style of mineralization (eg. vein, stockwork, seam); modelling techniques (regularisation, dilution halo, perimeter to area and volume to surface area ratios), assessing dilutant grades; modern mineable resource optimisation and mineable shape optimisation (MRO/MSO) techniques for open pit and underground; internal/external or planned/unplanned or planned/operational dilution and loss; and, the mine reconciliation interface. Case studies will be presented highlighting modern techniques and industry faux pas.

“Adding Value through Appropriate Integration of Hydrogeology and Rock Mechanics Studies”
Pit slope optimisation, and through this the pit design, should be treated as an optimisation cycle in which iterative processes and data exchange between the mine design team, geotechnical engineers and hydrogeologists should take place to try and achieve the best pit design for a project, in accordance with corporate objectives. Often this combines consideration of aspects such as pit value, mine life and further exploration potential. The project risks increase with pit depth, such that minor changes in slope angles can be the difference between make or break for a project. Nowadays, new technologies are available for adding value to integrated studies and the benefits of early stage geotechnical and hydrogeological data capture can help identify areas of risk in the early stages of project development and allow a more focused and detailed investigation to be undertaken to maximise the reliability of the data, minimise the risk and optimise the overall project returns.

Senior Geotechnical Engineer
Current trends in information technologies have not surpassed mining industry, bringing a variety of options to collect, process and analyze different kinds of data generated at all development stages of the projects. The presentation will concentrate on some recent achievements in assessing geotechnical risk factors in underground mines and visualizing hazards in 4 D format (spacial and temporal representation) as well as monitoring possible influence of mining operations on the surface infrastructure in order to reduce possible impact and make stakeholders aware of the actions needed. Underground part will cover possible applications of state-of-the art geotechnical hazard management system developed by Mira Geoscience (Canada) and applied successfully in major underground mines to produce quantitative forecast of possible geotechnical risk. Surface part will be based on DMT own development allowing timely recognition of changes in the surface environment around the mine and reacting in appropriate manner.
