The Gorsko Shaft was excavated to the depth of Level I in the first half of the seventeenth century, and was probably completed in 1622. in the nineteenth century, the shaft was extended. in 1954, the Gorsko Shaft was filled up to a depth of approximately 6 meters below the ground. Inflows out of the Gorsko Shaft were first observed in the shaft bottom and in Fryderyk August chamber. Through suffusion and leaching salt formations, migratory waters caused soil settling and structural damage to the shaft top building. In February 2011, a technical design for the sealing of the Gorsko Shaft was developed, which calls for cementing work and the elimination of surface water inflow through the shaft into the mine workings. Engineering work related to the restriction of the flow of water into the Gorsko Shaft began in December 2011.
