Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.

Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
The open pit coal mines production system consist mainly in a string of equipment starting with winning equipment (bucket wheel excavator), on board hauling equipment, conveying equipment, transfer devices, spreaders or stackers, used alternatively for overburden removal conveying disposal and for coal winning conveying stacking. This
Reduced Production Raises Cash Costs There is an inverse relation between the level of production and the per ounce cash cost. Higher production helps reduce the fixed cost components. Lower production can result from: • Safety related production stoppages • Technical problems • Lower grades
A large proportion of openpit mining is explained by its advantages over underground mining such as higher labor productivity (1011 times in coal mines), lower production costs (34 tim es) and shorter terms of mine construction (23 times) [1]. In Russia, the proportion of openpit mining in the total coal production currently stands at about
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US.
