Pilot Long Distance Large Pipe Shield Support Applied to Construction of Mine Inclined Shaft in Deep Overburden Soil
Abstract：In order to successfully pass through the deep overburden soil and quicksand section for the mine inclined shaft construction, two construction plans of a pilot long distance pipe shield support and ground freezing method were provided for the design. With the plan verification as well as the technical and economic comparison, the gnidenee long distance large pipe shield support plan was applied. A gnidence pipe drilling technology was successfully applied to conduct the pilot long distance large pipe shield support and the slip-form construction in Jingfang Mine. The project practices showed that the pilot pipe drilling technology was applied to make the once support length of the pilot pipe shield reached to 160 m. In comparison with the ground freezing method, the pilot pipe shield support could make the construction period reduced by 77% and the cost could be reduced by 83%. Meanwhile, the construction method was successfully promoted to Zhuangzihe Mine.
