Hydraulic mining uses water to erode surface material to expose minerals. Fracking (hydraulic fracturing) injects high-pressure fluid deep underground to fracture rock and release oil or gas.
It caused catastrophic erosion, buried agricultural land and towns under silt, and destroyed river ecosystems for miles downstream.
It was the contemporary verb (now archaic) meaning 'to engage in hydraulic mining' or 'to extract using hydraulic mining methods'.
