Coal Ash Usage, Germany
SENES prepared a literature review which examined research studies and field applications on the use of coal ash as an alkaline amendment for amelioration of acidic drainage from waste rock, and for treatment of acidic mine water. SENES subsequently performed geochemical modelling of the flooding of an historic mining region, to assess the effects of alkaline coal ash on mine water quality which had been used as sealant material in the underground drifts and as an alkaline backfill within caved zones throughout the mines. The assessment included evaluation of data on the geochemical characteristics of coal ash and the simulation of mine water quality in a vast area of mine workings affected by AMD.

Coal Mining, North America
SENES completed a comprehensive study in 1996 on the North American practices associated with coal mine waste management. The study included both state-of-the-art literature searches and direct correspondence with mining industry sources. (Confidential Client)

Coal Mining, Nova Scotia
SENES conducted a strategic management workshop for the Cape Breton Development Corporation, Nova Scotia - a coal mining company - titled "Strategic Planning Session for the Environment". The objective of the workshop was to help the top management of the company identify, prioritize and draw up an action plans for effective environmental management of the company's operations including potential closure liabilities.

Coal Mining, Poland
SENES has recently been retained by Industry Canada to develop an environmental joint industry/government workshop to be held in Poland to address the environmental issues related to coal mining operations, rehabilitation, decommissioning and closure. (Industrial Canada)

Coal Discard Dumps, South Africa
In association with Pulles Howard and DeLange (PHD), SENES completed a geochemical modelling assessment of decommissioning options for three large coal discard piles in South Africa. The modelling performed by SENES included: physical modelling of the transport of heat and air in the piles; geochemical modelling of the generation of acid and the production of contaminated seepage from the piles over the short-term and long-term, for several pile rehabilitation options; and, hydrological modelling of an ideal engineered soil cover that was proposed for remediation of the piles. (PHD)

Coal Refuse Piles, North America
SENES performed a geochemical modelling study of the effects of various treatment options (e.g. compaction, alkali addition, bactericide) on the generation of acidic drainage from coal refuse piles. This study included simulation of several small coal refuse test piles, as well as a large acid-generating pile, and comparison of the model predictions to monitoring data collected from the site.

Coalspur Project, Alberta
SENES provided expertise for the assessment of the environmental effects of developing an open pit coal mining operation in the Albertan foothills. Tasks undertaken included the development of estimates of air and water emissions to evaluate the potential atmospheric and aquatic impacts. (Dentherm Resources Limited)

Quintette Coal Mine, British Columbia
SENES was lead consultant on the preparation of a comprehensive environmental impact assessment for the largest coal mine in Canada - Quintette Coal. The assessment involved all aspects of the environment, including: air quality, water quality, land use, and biological studies. The environmental permit applications were completed under the direction of SENES and following extensive regulatory review, the necessary approvals were received. (Quintette Coal Limited)
