Supporting practice of Great cross section chamber under the soft aquifer
Abstract:In order to deal with the difficult of soft aquifer supporting large cross section chamber at the Lingdong coal mine, deformation and stability of the chamber were analyzed by FLAC based on the initial supporting design, on this basis the supporting design and optimization program were put forward. In the course of practice aimed at supporting the emergence of some problems and technical difficulties, the corresponding solution was given. The scientific and technological superiority of the above-mentioned technology were verified through the final construction effect.………..(10 Points, Times New Roman)
