Calculation of pillars at underground dissolution of salt deposits
Authors:
Abstract
At domestic brine fields deposits of rock salt of various thickness (from 40 to 700 m) and depth (from 300 to 1400 m) are developed by underground dissolution, through wells. As a rule, cylindrical chambers of 100 m diameter are used. The chambers are arranged on a 200x200 m grid, and the width of inter-chamber pillars is 100 m. Such sizes of pillars are insufficiently justified due to limited experience of underground dissolution and lack of tested solutions. As a result, there is a danger of pillars destruction and surface shifts.
