摘要
A method of solution mining a subterranean mineral ore deposit such as trona ore in which a borehole is drilled from a subterranean mechanically-worked mineral ore mining operation to connect a mineral ore bed to be solution mined, using subterranean drilling apparatus located proximate to the mechanically-worked mineral ore mining operation. The mineral ore bed is isolated from the mechanically-worked mineral ore mining operation by passage of the drilled borehole through an impermeable layer adjacent to the mineral ore bed to be solution mined. The mineral ore bed is then solution-mined using a mining solvent introduced into the mineral ore bed to solubilize the mineral and form a mining solution, and the resulting mining solution is withdrawn from the mineral ore bed.
