ABSTRACT:
Disclosed is a method of connecting two or more subterranean cavities in a deposit having a potassium chloride-rich stratum which contains sodium chloride and which is disposed above a potassium chloride-lean, sodium chloride-rich stratum. The method comprises drilling at least two adjacent wells into the sodium chloride-rich stratum, establishing a chimney filled with insulating fluid at the bottom of at least one of the wells, extracting ore from the potassium chloride-lean stratum with solvent, raising the roof of the cavities by incrementally raising the insulating fluid level and allowing the cavities to grow laterally until the cavities connect.
