ABSTRACT In-Pit Crushing and Conveying (IPCC) systems are receiving more attention today due to current characteristics of open-pit mining operations and what is expected to occur in the future. Today, it has become more necessary than ever to reduce the cost of truck haulage, which accounts for roughly half the operating costs of …

In open pit quarry operations the loading of the blasted rock for transportation to the primary crusher house involves either power-shovels. Any size of primary crusher may be used for hand-loaded rock; it all depends upon how much secondary shooting, and hand sledging, the operator feels he can afford. So called "one …

Mining - Strip, Open-Pit, Quarrying: It has been estimated that more than two-thirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, …

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture …

We know that open-pit mining operations mainly include drilling, blasting, mining, transportation and dumping. Blasting is a very important part of it. Blasting costs account for 15% to 20% of the total cost of open pit mining. Moreover, the quality of blasting directly affects the working efficiency and total cost of the mining process.
