Below you can find a brief description of example projects from recent years, showcasing our competence and expertise in our main fields. This is just a small excerpt.

2D Finite Element Model, Kazakhstan

To secure a a US$ 260 million loan for restructuring and development of the Vozkhod chromite mine in Kazakhstan, Yildirim Group selected DMT for the preparation of a geotechnical model to prove that the selected mining method and the intended dimensions of the mine layout were viable. The bank’s engineer had requested additional engineering and reporting work for the investment in the expansion of facilities and intensive mine development works, including evaluation of deformations and proof of stability of underground workings. DMT also reviewed documentation regarding geological/geotechnical parameters, mine layout and applied rock support systems. After collecting the relevant data, DMT produced a 2D Finite Element model for the mine which was judged to be of a “high standard” by the bank’s engineer.

Technical Due Diligence, Australia

NMDC Limited, India awarded DMT a contract for carrying out Technical Due Diligence of an iron ore project in Australia, which resulted in NMDC successfully acquiring a stake in Legacy Iron Ore. DMT assessed the following:

  •  Analysis of licenses and approvals critical to the viability of the mineral assets
  • Geology, resources & reserves and the estimation methodologies employed
  • Description of the mineral resource i.e. estimated inferred/indicated, mining dilution factors, mining recovery factors etc.
  • Evaluation of project utilities including Water/Power, infrastructure and logistics.
  • Environmental and social impacts.
  • Financial assessment- CAPEX & OPEX
  • Risk assessment

Geotechnical study for a new potash mine, Russia

In 2016 DMT carried out a number of analyses for K-Potash Services for their planned multi-seam potassium mining. This included determination of the relevant rock mechanical parameters for the salt rock (e.g. creep behavior) and stress analysis via large-scale numerical models for the examination of the mutual interaction with host rock. DMT also performed a stability and deformation analysis as well as the expansion design for the planned underground mine workings (main roadways, longwall, room and pillar mining system). Based on the results of our studies and our mining Expertise, we were also able to provide recommendations for the adaptation of the originally planned design.

Exploration of a Lignite Mine, Turkey

POLYAK EyÜretim Madencilik nez Enerji San. ve Tic. A.S. contracted DMT for the Exploration of the Kınık sub-bituminous coal deposit in the Soma coalfield, Turkey. DMT recommended an exploration programme according to international standards, including hydrogeological investigations, geophysical borehole measurements, methane measurements and geotechnics. Within the scope of the investigation DMT was responsible for the planning and supervision of the exploration and of the drilling campaign. Furthermore, we undertook a 2D seismic survey and produced a JORC compliant 3D deposit model to interpret the structure of the intensively faulted deposit, which enabled us to reduce both exploration period and costs.

Resource estimate for a graphite deposit, Tanzania

DMT was appointed to prepare a Mineral Resource estimate in accordance to NI 43-101 and prepare a Competent Persons Report for a graphite deposit. DMT oversaw and guided the exploration project, evaluated the borehole data and trench data and developed a geological model using DATAMINE. DMT liaised closely with the laboratory to ensure ISO 17025 accredited methods were being used for the analysis. Finally, DMT prepared a CPR on the project.

Bankable Feasibility Study for Construction and Operation of Inaglinsky GOK, Coal, Yakutia

Preparation of a Bankable Feasibility Study (TEO Study) for Construction and Operation of Inaglinsky GOK. This study was preceded by the work stage in a Scoping Study format involving preliminary decisions on viability of construction of the GOK. The Scoping Study included analysis and subsequent techno-economic assessment of different options. The second stage of elaboration with development of the Bankable Feasibility Study involved further increase in the level of detail of Inaglinsky GOK’s construction concept. The work outcomes included development of an economic model on the basis of precise calculations made for various phases and construction facilities, thus enabling determination of final costs of the project.

Potash Gravity & Magnetic Survey, India

Mineral Exploration Corporation Limited (MECL) appointed DMT for carrying out a Gravity & Magnetic survey for potash in the Bharusari block, Rajasthan, India. Within the scope of work, DMT recorded 4475 Gravity-Magnetic-DGPS stations in a 500m X 500m grid, then processed and interpreted the data. The report was successfully completed within the given timeframe.

Feasibility study for expansion of iron ore open pit and processing plant, Peru

Feasibility study for the expansion of mine production and mineral processing from 10 Mt/a to 20 Mt/a at the Shougang Hierro mine. DMT's tasks included supervision of sampling for metallurgical test work, the preparation of a test work program addressing different ore types, lab and batch scale test work and pilot plant tests. DMT was also responsible for the detailed technological scheme development of this large-scale project, which took four years to complete.

Conceptual design of a high pressure underground water dam for a coal mine, Turkey

DMT was contracted by TTK Genel Müdürlüğü to determine the optimal location and optimal design for a high pressure water dam based on geological, geotechnical and operational conditions. The project involved a stability analysis for the designed dam for different water pressures as well as design of the temporary ground support for the dam construction stage. Our experts were also on hand to give recommendations on technical implementation during construction.

Production increase by improved rock burst prevention and gas Drainage, Russia

DMT was contracted by SUEK for the assessment of rock burst risk according to the DMT System. With professional numerical modelling we were able to determine potential critical stress zones during development and extraction. Furthermore, numerical modelling of loosing zones caused by extraction was used to optimize the location of surface gas drainage holes. We assisted the client when dealing with authorities for measures which were not in line with the mining regulations and also gave recommendations on a mandatory control system.

Water model concept, South Africa

DMT was contracted for a Model Concept of the East Rand Basin, South Africa. We produced a holistic model including:

  • groundwater,
  • water run-off dumps,
  • river water,
  • surface water
  • and mine water. 

Feasibility study for pumped storage power plants in old coal mines, Germany

DMT was a key member of a publicly funded research project with the goal of transforming a German coal mine into a pumped storage power plant to store energy from regenerative sources. Together with University Duisburg-Essen, Ruhr University Bochum, RAG and RISP we undertook the task of developing the idea into a sound project proposal. DMT collected data and evaluated all aspects of the project, from safety during construction and operation to post-mining effects and costs. The positive feasibility study will lead to construction of a prototype.

Mine Waste Management, Serbia

DMT is involved in a four-year project to improve the mining waste management system in the Republic of Serbia. The project is funded by the European Union (90%) and by the Government of the Republic of Serbia (10%) and is being carried out by DMT together with PLEJADES GmbH. To bring Serbia's national legislation in line with EU directives, a cadastre of mining waste facilities is to be implemented. This cadastre will cover some 200 active and 200 to 250 abandoned mining waste sites and contain risk assessment, characterization of mining waste and its classification. Scope includes preparation of guidance documents, site inspections and data collection, geotechnical analyses, preparation of case studies for mining waste sites with hazardous waste, non-hazardous waste and inert waste and provision of training. 

From its long history of working in the mining industry, the DMT group also offers a number of specialist services for the mining sector. These include: underground gas ventilation systems; fire prevention; rock mechanics; conveyor systems; hydrogeology and water management; component and wire rope testing as well as coke processing technology and radiation protection.
