| Mine Closure and Reclamation |
Protecting the environment and transitioning properties to new land uses
The combination of our internationally recognised experience in all aspects of mining with our knowledge of local requirements makes us the partner of choice for many clients embarking on mine closure projects.
We recognised the increasing importance of mine closure to the industry in the early 1990s. We made it a central focus and have since worked closely with industry and governments to develop the current state-of-the-art practices that meet today’s necessary requirements and standards.
Mine closure planning is necessary at all stages of a mining operation. Current best practice dictates that all mines should be ‘designed for closure’. Closure plans and related financial securities are also required for permitting in many jurisdictions. Recent changes to standards for accounting of “asset retirement obligations” have created an additional need for mine closure planning and cost estimation. We routinely develop appropriate mine closure plans to meet these, and your, needs.
Implementation of closure plans begins with the engineering studies, testing and monitoring that translate plans into construction drawings. Our experience in these stages includes detailed closure designs for mines throughout the world. Implementation then continues through procurement and construction. Our knowledge here ranges from assistance with tendering and construction QA/QC, to delivery of complete design-build packages.
The importance of mine closure to our business has led to a high awareness of closure requirements by all of our technical specialists. Reclamation and closure planning is routinely incorporated into feasibility studies, operating plans, due diligence assessments and many other areas of our work.

| Environmental Geochemistry and Acid Rock Drainage |
Predicting, controlling and managing mine drainage chemistry
Managing mine drainage water quality is a critical concern for all mining operations because discharges must typically meet stringent water quality standards set by local, regional and national governments. Acidic drainage remains the most significant issue due to high concentrations of metals, and costs of treatment to achieve acceptable levels. However, in the past decade or so, awareness of leaching under non-acidic conditions has greatly increased.
Accurate prediction of leaching effects, and design of practical and proven control measures, is often critical to the feasibility of your projects. These issues are encountered during permitting of new mines, optimisation of existing operations, development of closure plans and remediation of abandoned mines.
The cornerstone of our approach is that the release of ARD (acid rock drainage) is controlled by geological conditions. We therefore work with your geologists to understand how the geology of your property affects drainage chemistry, and how it can be used to limit potential impacts and engineering costs.
ARD potential is also affected by local climatic conditions. We have experience in the full range of global climates including permafrost in the high arctic, temperate regions, and both wet and dry regions of the tropics.
Our global team of experienced engineers and geoscientists will assist you to develop cost-effective solutions to mine drainage issues ranging from severe acidity to dealing with unusual trace elements. Our experience includes addressing drainage chemistry at all stages of the mining cycle.

| Contaminated Sites |
Approach
Aditya Coal Consulting has extensive experience with the assessment and remediation of contaminated sites (including metals, hydrocarbons, chlorinated solvents, and a range of hazardous wastes) for clients from the petrochemical, real estate, manufacturing, transportation, metal processing and port industries.
Aditya Coal’s strengths in this area lie in our extensive knowledge of statutes, regulations and guidelines in the jurisdictions in which we work, and our proven ability to collect high-quality legally-defensible data applicable to remediation or demonstration of the absence of any contamination in soil, air or water. Our geochemists and hydrogeologists have a thorough understanding of sampling protocols, and we sub-contract reputable drillers and analytical testing laboratories.
Aditya Coal’s engineers develop remedial alternatives and rank them according to criteria appropriate to the particular objectives for the site. Aditya Coal works closely with the client and the other members of the professional team to ensure that remediation objectives are clearly defined and integrated with engineering, development and management goals to achieve a cost-effective solution.

- Phase I and phase 2 assessments
- Remediation design and costing
- Implementation and monitoring of remedial solutions

| Environmental and Social Services |
Facilitating decisions: permitting, risk management and social license
Whether planning a mine, staying on course, suspending operations or closing a facility, mining companies need to satisfy numerous and often complex regulatory requirements while simultaneously addressing community expectations. The complexity can be compounded by a need to prove to investors that risks are handled appropriately. We can assist you in achieving your ultimate goals, whether they are an environmental permit, an investment decision, a “social license” to operate or a closure certificate.
Our practical experience with a wide range of mining projects assures the identification of environmental and social issues critical to a venture’s success. To this end, we work with mining companies to overcome any challenges; with financial institutions to identify and manage risk; and with environmental regulators to provide relevant assurances and solutions.
Environmental and social studies often require a multi-specialist approach. Technical knowledge combined with project management expertise ensures the appropriate level of study is undertaken. Our professionals have the skills and experience to reduce your risks whilst meeting project objectives in a cost and time-efficient manner.
We can assist you with monitoring programs, audits and reviews to evaluate the effectiveness of existing management systems, and identify weaknesses and risk areas in terms of potential environmental failures and community grievances. Audits also provide a forum for the exchange of technical knowledge and identification of cost reductions.
Our environmental and social data management skills can turn your data into information, enabling you to make decisions in real time. Combining appropriate technical skills and experience with available computer technologies enables the processing and integration of large and varied spatial data sets of environmental, socio-economic, mining, hydrological and geotechnical information. Outputs can be analysed and compared, allowing for multi-disciplinary decision support and implementation of unique and cost-effective solutions.
