  • Paper Practical waste rock dump and stockpile management

    Open pit mine slopes are designed with a serviceable life of no more than 10 to 20 years. As such predicted and well-managed failures or landslides are usually considered acceptable. Waste rock and low-grade ore are often placed in constructed rockfill dumps and stockpiles which range in heights from 50 to over 300 m.
