Location: All real estate value depends on location. In case of mining the location is predetermined by nature. Also, unlike housing, quarry locations in relation to the m arkets determine how much transportation cost will have to be paid by the customer. Transportation costs can double the delivered price of stone within 20 miles from the quarry.

The EX1 excavator will remain in a stationary position for most of its use, feeding blasted rock into a mobile crusher before it's transported to the secondary crusher and then processed. The two machines will work together, moving a few meters once or twice a day as the excavator works its way through the blasted rock, Müller explains.

Blockage occurs when a rock, because of size or shape, bridges across the crusher feed opening so that the crusher forces cannot be applied. This blockage can also prevent empty. This is a beneficial condition for blasting in that the existing air space acts as a cushion and therefore reduces excessive shock transfer to the crusher.

Truck transport adds an additional 12 to 15 cents per ton-mile to the delivered cost of the stone [2]. For example, if the plant is 20 miles from the job site, the cost of transportation will be about $2.40 to $3.00 per ton. Rail and barge transport have lowered costs per ton-mile; however, very few quarries are on rail lines or rivers.
