A comprehensive investigation of the relationship between propulsion speed and water influx in coal mine TBM inclined shaft projects

Abstract To explore the influence of water inflow on the safe and efficient tunneling construction of TBM in water-rich Luohe Formation sandstone. Based on the tunneling data at the main inclined shaft TBM construction site of Kekegai Coal Mine, a relationship model between tunneling speed and water...
