Surface mining with scraper/slusher
I'm trying to determine the feasability of using a scraper/slusher
for stripping and moving material to my placer washplant.
The quota is approx 250cu.yd in under 4 hours.
Since the washplant, oversize conveyor, and ore pipeline take a day to move, the dragline distance can be optimised. The max depth to bedrock is approx. 35'
Selection of equipment remains obscure. Is there a rule of thumb or standard formula that I could refer to? Most information I come accross is aimed at monster machines in the coal patch and large scale gravel operations. The equipment used in underground applications seems simple enough. But the volumes seems a little low.
If there's any literature you can recomend?
