Technology improvement of large dip downhill fully-mechanized excavation in rock roadway
The ability of the fully-mechanized excavator to"retreat"in the excavation of the rock roadway of the large dip downhill is limited,and the operation failure of the belt conveyor affects the excavation efficiency.In order to address the problems of insufficient"grip"ability of the track of the fully-mechanized excavator,upstream water accumulation during excavation,dumping,breaking of the secondary conveyor belt,sliding of gangue,and difficulty in material transportation,the contact area between the track and the floor of the fully-mechanized excavator was increased.The use of extended oil cylinders to drive and improve its walking ability,as well as the addition of anti slip and anti fly debris belt breaking devices for the tape conveyor,has reduced its operational failures and achieved good results,improving construction quality and excavation efficiency.
