Two auxilliary mine shafts in Zhuxianzhuang and Taoyuan Coal Mines were equipped with a metal rigid installation equipment by a single operation and a four-deck platform. Due to the permanent headframe built after the installation of shaft equipment in Zhuxianzhuang Mine, it used a shaft sinking headframe for the operations of stabilizer, hoister and deck platform. In Taoyuan Mine, the auxilliary mine shaft was equipped after the installation of a permanent headframe, A multi-rope drum was equipped for hoisting and resin bolts were uesd to fix the guide beams. The drilling and setting of resin bolts were operated on the first deck of the multi-deck platform and the installations of bearing beams, guide beam and walk way were operated on the second deck of the multi-deck platform. The beams for walk way, cable and guide were installed at the same time. The steel combined guide was fixed with the beam by bolts. The compressed air pipeline, water drainage pipeline and water supply pipeline were installed from the bottom of the shaft to the surface. In the shaft, two power cables, one communication line and one signal line were installed with two stabilizers and wire ropes.
