Abstract
Solution mining method particularly adapted for recovery of potash and the like from relatively thin, inclined strata at substantial depths and involving the dissolution of ore strata, overlain by insoluble strata, while leaving the remainder of the formation in place. Water is injected down a bore hole at a predetermined rate and, being much less dense than present brine, flows in an updip direction along the top of the cavity to a forward mining face remote from the drill hole. Loaded, heavy brine flows downdip along the bottom of the stratum to an outflow pipe communicating with the bottom of the bore hole.
