The future success of Navy-Marine Corps operations in the extended littoral battlespace will depend critically on organic mine countermeasure capabilities. A battlegroup commander will require tools to rapidly detect, classify, and identify mines and form a tactical picture of mined areas, so a decision can be made to punch through the minefield, avoid it, or wait for dedicated mine countermeas...

Mine planning is a typical engineering design function which integrate the disciplines of geology, metallurgy, geotechnics, mining and economics. The numerous uncertainties associated with geological understanding, the exposure of people to potential hazards in the work place and the need to provide a specific dollar outcome, requires a proper assessment of the risk. This paper identifies the s...

Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

Short-term production plans are the basis for operational mine production schedules. They concentrate on making long-term mine plans operationally feasible. Furthermore, some variables such as ore grade and tonnage govern mine production systems and cause uncertainty in the supply of raw materials to the mills. Due to the quality variation of material, short-term production optimization is an u...

There are many reasons to mine landfills. For example, metals are increasingly shifting location from the Earth’s crust through human society into landfills. These new mines are located closer to the market, in contrast to traditional mines in the countryside where the metals are deep inside the crust requiring huge amounts of energy to be extracted. In addition, metals in the landfill pose a p...

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 determination of the “optimum pit limit” of a mine is considered to be a fundamental problem in mine planning as it provides information which is essential in the evaluation of the economic potential of a mineral deposit, and in the formulation of long-, intermediate-, and short-range mine plans. A number of mathematical techniques have been proposed to solve this problem, some of the more ...

production planning of an open-pit mine is a procedure during which the rock blocks are assigned to different production periods in a way that leads to the highest net present value (npv) subject to some operational and technical constraints. this process becomes much more complicated by incorporation of the uncertainty existing in the input parameters. the commodity price uncertainty is among ...

Geometallurgical mapping is a new team-based approach that documents variability within an orebody and quantifies the impact of geology (host rocks, alteration and structure) and mineralogy on grinding, metallurgical response and metal recovery processes. The quantitative, spatially constrained database that results can be readily integrated into 3-D block models and mine planning activities. T...

Mine planning, permitting and operation require reliable water technology in all its aspects: water inflow, water use, water disposal and discharge, and water impact. Mine water evaluations are relied upon by mining companies, mine regulators and the public to determine whether the mine is technically feasible, optimally designed, financially sound, socially acceptable, and environmentally beni...
