An Optimized Open Pit Mine Application for Limestone Quarry Production Scheduling to Maximize Net Present Value
The limestone production is a very important economic sector in Jordan [2] . The limestone production in Jordan is shown in Figure 2. Many of the limestones belong to the quarries that are located near to urban territories in the Irbid district (Sammad area), north of Jordan. Most of the mining operation is mainly open cast mining.
The limestone production scheduling for an open pit mine can be described as determining the order in which 'blocks' should be extracted to achieve a specific goal, while taking into account a range of physical and resource restrictions [].The availability of high-quality raw materials in sufficient quantities is critical to the success of a cement plant's operation.

cast mining from the Adanakurichi limestone mines in Tamil Nadu India for cement manufacturing. Mining of Limestone from the Adanakurichi limestone mines is facing a complex hydrological problem due to the seepage of water from the limestone aquifer and it causes ooding in that areas, which disrupts the mining operations. To control the groundwater
Drilling and blasting control is interpreted as a first category of control [i]. It is viewed as a stabilization system maintaining at a desired level the lump size of the exploded rock mass and the content of valuable component in it, taking into account the stochastic
An efficient dewatering scheme helps the management authority of mines in decision-making on the minimum quantity of withdrawal of groundwater from open-cast mines to avoid excessive groundwater withdrawal from the mines. Karst aquifers are characterized by a dual flow system consisting of Darcy flow and non-Darcy flow in the Matrix and conduits …
