Estimation of bearing capacity of supporting pillars during in-situ leaching of thick salt deposits (in conditions of Yar-Bishkadak brine field).
Abstract
The Yar-Bishkadak field, which supplies brine to a number of chemical enterprises in Bashkiria, extracts a section of salt deposit with a thickness of 200-700 m, with the thickness of overlying rocks being 400-500 meters. Development is carried out by isolated chambers, which are created by salt leaching through wells drilled from the surface. The adopted technology - stepwise leaching - ensures the creation of chambers of approximately cylindrical shape with a diameter of 80-100 m and height at the end of mining equal to the thickness of the salt deposit (the height of individual chambers currently reaches 100-150 m) ....
