Abstract:

Briefly introduced the installation methods of large and medium-sized skip，details of the application after the disintegration of piecewise installation scheme in blind shaft，Linglong gold mine.In view of the large and medium-sized skip need to collapse to implement the segmentation assembled by wellhead roadway and cage to transport the blind shaft，through the site condition and equipment force analysis，integrated with high strength flange connection，reaming bolt positioning and stagger the collapse location method and process，designed the scheme of  skip disintegration.The scheme of  skip disintegration overcome the skip size，disassembly and assembly of large deformation，the connection strength is low，making detailed and reasonable skip sorting scheme，successfully resolved the problem of  the installation of large and medium-sized skip in blind shaft after the disintegration.

Key words: skip, disintegration, blind shaft
