Exploration of Driving Construction Technology for Vertical Blind Shaft under Complex Geological Conditions
Under complex geological conditions, unclear understanding of the geological conditions of vertical blind shafts, difficult driving and masonry construction techniques, and long construction period have significant impacts on the infrastructure construction of underground mines. The vertical blind shaft of the infrastructure mine is analyzed through the construction data of raise-boring machine, and the distribution of the fractured zone of the vertical blind shaft is preliminarily inferred. Based on the geological conditions of the vertical blind shaft, targeted lifting and blasting technical parameters and effective technical measures are formulated, and the rock fracture zone is successfully passed through during the driving construction.
