The vertical
discharge is a difficulty during construction of shaft boring machine, hence,
the technology of vertical discharge for fullface
shaft boring machine is proposed. First, the technical principle and discharge
capacity of the vertical discharge system are introduced. And then some
technologies such as slag particle size control, slag scraping of scraper
conveyor, slag removal at blind area and slag transfer of bucket elevator are
analyzed. Finally, the boring tests under various conditions with different
thrust forces and torques are carried out. The results show that the vertical
discharge technology is feasible, the particle size is controllable and the
discharge system runs normally. The vertical discharge of fullface shaft boring machine is a feasible method for mechanized
continuous discharge, which helps to advance the construction technology of
shaft boring.
