Mineable reserve determination is one of the important parameters in economic profitability and the safety of underground mining production. The fluctuations in the metal prices will lead to a change in the cut-off grade, and as a result, the mine la

Solving the stope boundary optimization problem is the primary step that should be taken after selecting an underground mining method. Obviously, this solution should be optimal because suboptimal boundaries may lead to wasting both mining capital an

It is very difficult to predict the emission of coal gas before the extraction, because it depends on various geological, geographical and operational factors. Gas content is a very important parameter for assessing gas emission in the coal seam duri

Gas emission in underground coal mines is of crucial importance. It is the potential cause of several health and safety issues such as gas explosion and gas poisoning. The emission of toxic and explosive gases in underground workings creates an unsaf

Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not consideri

Optimizing level intervals is one of the main issues in underground mining operations with steeply-dipping deposits. Specifically, it has a direct effect on the economy, as well as, the technical decisions of a mining project. Any deviation of the le

Design process for open-pit mines starts with determining ultimate pit limit (UPL) that includes the maximum profit. There are different methods to determine the UPL, including manual and computer methods. Computer-based methods are categorized to in
