Recent changes in the fossil-fuel energy sector require coal mining industries to plan for future, including developing procedures decommissioning and closure associated with mines. In surface mining, geotechnical issues of include long-term stability pit slopes, particularly as is gradually filled water. This paper investigates such slope issues, emphasis on conditions prevailing Amyntaion lig...

Historically, tailings facilities have been designed primarily with consideration of the mine’s active life. This is problematic, as lifespan a dam may far exceed life mine. Over time, it expected that these structures will transform into mine waste structure and then eventually landform. In Alberta, Canada, owners can submit decommissioning, closure, abandonment (DCA) plan completion reports t...

Given a short term mining plan, the task for an operational mine planner is to determine how the equipment in the mine should be used each day. That is, how crushers, loaders and trucks should be used to realise the short term plan. It is important to achieve both grade targets (by blending) and maximise the utilisation (i.e., throughput) of the mine. The resulting problem is a non-linear sched...

It is well recognized that software tools for strategic underground mine planning are lacking, and that the demand for these tools will increase as deeper deposits amenable to underground mining continue to grow in value. While a number of optimization techniques have been developed for stope layout design and progress continues to be made in the area of production scheduling, both of these min...

Mining operations have a big environmental impact wherever they are located. Unsuccessful operation and/ or inadequate planning for closure has in several cases increased the impact, causing costly liabilities without finance. The consequence is, generalized, difficulties to get permits, some countries more less impossible. Metals and minerals are, however, necessary our society even so with “g...

Mining causes changes to the environment and rehabilitation is necessary at mine closure. There is a lack of appropriate frameworks for mine site rehabilitation. In most cases, restoring the mine to previous conditions is challenging. Alternatively, mining companies can engineer ecosystems to suit new site conditions and aim for a self-sustaining and resilient ecosystem. In ecosystem design the...

The preservation of ecosystems surrounding mine sites and the rehabilitation disturbed due to activities is a key responsibility operators. In Canada, federal provincial regulations are established control mining assist operators in developing successful management system for tailings facilities, through planning, construction, operation closure. A Closure Rehabilitation Plan has been prepared ...
