IN-SITU LEACHING OF ORE DEPOSITS LOCATED IN IMPERMEABLE UNDERGROUND FORMATIONS

摘要

A method and system of in-situ leaching of ore deposits located within underground formations comprising non-porous and impermeable rock. The method includes hydraulically fracturing the impermeable formation containing an ore deposit to create a fractured zone within the formation. Then a flowable explosive is introduced into the fractured zone and detonated to rubblize the fractured zone to create a permeable zone within the formation that is suitable for in-situ leaching of the ore deposit.

1. A method of forming an in-situ mine comprising the steps of:
hydraulically fracturing a non-porous, impermeable formation containing an ore deposit, thereby creating a fractured zone; introducing an flowable explosive into said fractured zone; and detonating said explosive, thereby causing rubblization of at least a portion said fractured zone.
