The supply of nonferrous metals is increasingly tense, while resources with simple shallow and geological conditions are gradually reduced, and the development of resources with complex and deep geological conditions is imperative. The construction amount of the vertical shaft is only less than 10 percent of the total mine construction amount, but the construction period of the vertical shaft is 30 to 40 percent of the total mine, and the vertical shaft is a throat project for mine construction, so that the improvement of the construction speed of the vertical shaft is the key for accelerating the mine construction speed.
In the process of building the shaft of the vertical shaft, the probability of karst cave, large crack, fault fracture zone, fine crack and pore exposed from the shaft of the vertical shaft is high, so that the water inflow quantity often exposed from the shaft of the vertical shaft is high, and once sudden water inflow occurs, the water inflow quantity is larger than the drainage capacity of a water pump, the accident of flooding is caused[5]. Therefore, for the shaft of the deep vertical shaft, the shaft must be pre-grouted to ensure safe and rapid tunneling of the shaft, so that the effects of saving the construction period and reducing the cost are achieved.
The lowest underground mineral exploitation elevation of the lead-zinc mining area of the hair terrace of Yi-Jing-hong mining company Limited is at the middle section of 610 meters, and the mineral reserve with abundant reserves is still found below the middle section of 610 meters. The depth of a shaft of a blind shaft of the 112-line blank plumbum-zincite 112 line of the rough terrace is 960m, the elevation ranges from +910m to-50 m, the shaft is a circular shaft, the diameter of the shaft is 5.7m, the excavation diameter of the shaft is 6.5m, when the shaft of the shaft is excavated to the elevation of +481m, after grouting of a working face and grouting of a wall, the residual water inflow of the shaft is about 50m3H is used as the reference value. The wellbore water inflow is expected to increase substantially in the deep zone. In order to ensure the smooth tunneling of the engineering and eliminate the water trouble of the shaft, the Yi-nations macromining limited company decides to arrange an operation platform at the +670m middle section in the well for shaft pre-grouting.And the pre-grouting engineering needs to convey the equipment to an underground working platform, and the condition that whether large-scale equipment can be smoothly transferred and transported becomes the premise that whether the engineering can be smoothly implemented or not.
